Notes on the historic rise of the far right in Britain


Saturday 22 November 2025, by Thierry Labica


Against the backdrop of the bankruptcy of the historic two-party system, continued social brutalization, and after years of state racism and complicity in genocide, various shades of the British far right are now securing an unprecedented mass audience, which crystallized during a demonstration in London that brought together 150,000 demonstrators in London at the call of an avowed Islamophobic fascist. Fossil fuel interests, armaments, tax evasion and Israelism: the first benchmarks for understanding this evolution.


On 13 September 2025, a demonstration called by a notorious figure of the English fascist far right, Tommy Robinson (Stephen Yaxley-Lennon, his real name) brought together between 110,000 and 150,000 people in London. By its scale, unprecedented in Britain, this event marks a threshold of the audience of the far right — its mobilizing themes and affects — and of the fascist resurgence on an international scale.

Among the various factors and temporalities to be taken into account, one thinks of the historical trajectory of some twenty years in which the episode is part and comes to be a milestone: the racist focus on immigration owes little to the representatives of the far right itself and much to the violence of political and media discourse and to an ever more aggressively “hostile” legislative inflation for about fifteen years. It should be made clear from the outset that Labour’s responsibilities in this area from the end of the 2000s onwards were immense. Then we think of the political situation, both national and international, of which the demonstration of 13 September is a crystallisation: the deep crisis of the forces of the historic two-party system (Labour and the Conservatives), the audience for the far-right Reform UK led by Nigel Farage and Richard Tice, and the centrality of the Palestinian question and the genocide, against a backdrop of uninterrupted social degradation.

But to begin with, an overview of the personnel assembled and its main themes — as predictable as they may be — seems necessary. We will then draw attention to some, at least, of the material conditions of the event; the forces and resources which determine its possibility, the figures, and which define its content and expression.

Placed under the banner of “freedom of expression,” in other words, pluralist and democratic common sense, the event brought together a number of factions of the British far right, but also European, Australian, and American. The participants were able to hear speeches by Elon Musk and Éric Zemmour (accompanied by Jean Messiha), but also Petr Bystron for the AfD, and the Dutch Christian far rightist Eva Vlaardingerbroek (one million followers on X, more than 390,000 on Instagram and present on Fox news, GB news, and the online outlets of the far-right Sweden Democrats party, among others).

Also invited were the New Zealand Pentecostal Christian fundamentalist Brian Tamaki, convinced that the pandemic of 2020-22 or Hurricane Gabrielle were so many divine punishments for our wanderings away from God, between pornography, gay rights and abortion; the Israeli-Australian Avi Yemini, a former member of the Israeli army, a notorious provocateur who during a demonstration against the imprisonment of Robinson in 2018, declared himself “the world’s proudest Jewish Nazi”, Ezra Levant, founder of the Rebel News website and known as the “Canadian Steve Bannon”, and the British Katie Hopkins, regularly spotted alongside Robinson, a once-familiar mainstream media personality for whom asylum seekers are “cockroaches” while “our towns are festering sores, plagued by swarms of migrants and asylum seekers, shelling out benefits like Monopoly money”. Other characters of a similar kind, from Spain, Belgium, Ireland, or Denmark, were invited to offer their contribution.
The ideological matrix of the far right

Tommy Robinson, who initiated the 13 September demonstration, has become the focal point of this vast ultra-conservative and fascist movement nourished by a powerful victimhood imaginary whose martyrology now reserves a central place for him. Far from having been disqualified and marginalised by his past as a hooligan, a member of a notorious neo-Nazi organisation (British National Party from 2004 to 2005) and then the founder of an ultra-nationalist and Islamophobic organisation (English Defence League, EDL, from 2009 to 2013), Robinson has achieved the status of an exemplary incarnation of a victim of the system. A cheeky character of modest origins, abandoned by his father at the age of two, he has seen his rich career as a repeat offender (between expulsion from social networks for incitement to hatred and five prison stays for passport fraud, obstruction of justice, assaults, possession of drugs, mortgage fraud) turn into a title of bravery and glory in the face of the evil that is both oppressive and occult of a “system” whose crimes he is now revealing.

According to this version of things, the government is repressing freedom of expression (“free speech”) in order to prevent its role in the “great replacement,” “uncontrolled immigration” and the extinction of “Western civilization,” “the Islamization of our societies” and the threat of generalized “jihad.” A nightmarish vision concentrates the horror of this secret exterminatory logic of which “we” are the despised and ignored victims: “the rape of our daughters” by migrants accused not only of sexual assault on minors, but even worse, of organizing networks (grooming gangs) for the sexual exploitation of minors.

It is worth dwelling, even if too briefly, on this motif of “rape” (“of our daughters”). To begin with, there is an old panic in the face of racial mixing propagated by the non-white, savage and insatiable foreigner — many women, many children — who are incompletely civilized and, in fact, have remained in a more or less anomic state of nature and destructive of our norms. This fantastical character of the most classic racist imagination, proto-animal and presumed to be chronically overnumbered, would supposedly migrate to enjoy without limit or scruple the largesse of a national-social state to which he would never have contributed. While the brave and loyal taxpayer accepts various privations (and must be content with the distant promise of enjoyment dangled by a huge pornographic industry, from the front pages of the daily press with a large circulation), the migrant profiteer is then guilty of the general “civilizational collapse.”

It should be noted that neither Robinson nor Musk, nor Zemmour, nor Bystron, manage to refer, even in a cosmetic and opportunistic way, to which concrete social dimension of the problem could be displaced on the “civilizational” terrain. Typically, this is a case of fantastical avoidance and recoding of a truly terrible reality; the systemic neglect and abuse of millions of children in the United Kingdom, most often suffering in the silence of words they do not have, the impoverishment of all protection, care and follow-up structures, and exposed to a whole repertoire of sexual abuse and violence, a dark continent of which the dedicated organizations claim to perceive only the small emergent area. [1]

This imaginary of “rape” (and all its dark charge of repressed appetites) is thus that of a primitive jouissance at the origin of the “civilizational” collapse to which “multiculturalism” is working. It goes without saying that it remains — and must remain — disconnected from any issue of male domination, criticism of patriarchy and gender violence in order to be recoded against critical feminist thought (domestic, sexual and sexist violence — including rape — feminicide, socio-sexual relegation or the violence of child poverty that befalls millions of “our daughters” never seem to have the same rank as a mobilizer of affects here – and in truth, here do not exist, or no longer exist, at the end of what bears the features of a sadistic voyeuristic erotic reconfiguration that also seems to presume a certain fatality of rape in the last instance).

In this perspective, the “multiculturalist” left, feminists and anti-racists, as soon as they question the protective authority of fathers, brothers and husbands (over “our daughters”), and as soon as they defend the rights of migrants, are attributed a direct responsibility in the “social, moral and civilizational disaster”. Or, to quote Robinson in his video “The Rape of Britain: Part One”: “No country in the world is unaware that our government, our social services, and our police forces are sacrificing a generation of our daughters at the hands [sic] of the altar of multiculturalism [...]; There are still young girls, in every city and every big city, who are taken from us, taken from their mothers, as sex slaves at the hands of Islamic gangs.” This same motif can be found almost word for word in the intervention of Petr Bystron, of the AfD, and his defence of “our struggle” in Europe “for 2000 years”: “We don’t want our daughters, our sisters, to be raped. We don’t want our brothers, our friends, to be stabbed when they defend them.”

Elon Musk, in giant screen version, “clarified” the fundamental problem in his own way: “what I see happening here is a destruction of Britain, initially a slow erosion but rapidly increasing erosion of Britain with massive uncontrolled migration. A failure by the government to protect innocent people, including children who are getting gang raped. It’s unreal.”

For Musk, “there’s so many on the left that want to just crush debate and put people in prison just for talking, as you [Robinson] were, just for speaking their mind.” And in addition to how “the government did nothing and tried to hide it – they tried to hide these horrific crimes” there’s the violence of the left, designated as responsible for the assassination of Charlie Kirk three days earlier in the United States: “The left is the party of murder and celebrating murder. I mean, let that sink in for a minute. That’s who we’re dealing with here.”

We understand then, if it were not clear enough, that it is against the “woke mind virus” and its logic of “cancelling” terror (to “prevent debate and put people in prison”) that the banner of “free speech” has been unfurled, as a perfect This is evident after several years of generalized anti-woke political and media moral panic, and three days after the assassination of Charlie Kirk, attributed to this same “murder party”.

In the conclusion of this exchange, Musk confirms Robinson’s idea that the left is the occult force capable of controlling governments, and of organizing mass migrations from which it would then draw electorates that it would otherwise be unable to gather among the “authentically” national populations. “There’s a massive incentive on the left to import voters. So, if they can’t convince their nation to vote for them, they’re going to import people from other nations to vote for them… thus depriving the citizens of their democratic power. It’s really a voter importation thing.”

Here, more or less term for term, we find the classically anti-Semitic conspiracy imputations – but for someone who uses the Nazi salute, this cannot really be surprising – directed by the Hungarian far right against George Soros in 2017: Soros, the liberal “Jewish financier” supposedly working for the dissolution of national identities by putting his fortune at the service of a vast manipulation of migrants to Europe. This same motive, always accompanied by the quick but explicit reference to George Soros, is at the heart of a long interview offered on the far right and ardently pro-Israel GB News channel.

It should be remembered that this same victimhood of the “invasion” is the one that animated the neo-Nazi perpetrator of the Pittsburgh synagogue massacre in October 2018 (eleven dead). For the killer, Robert Bowers, the Hebrew Immigrant Aid Society (HIAS) was responsible for the arrival of Central American migrants and “evil Muslims,” which “likes to bring in invaders who kill people from here. I’m not going to stand by and watch my people being slaughtered.” The delusional justifications for the mass killings perpetrated by Anders Brevik in Norway in 2011 on young left-wing activists (71 dead) and by Brenton Tarrant in a mosque in New Zealand in 2019 (51 dead), were no different.
The origins of British racism

We can remain brief on the origin of these rhetorical figures and motifs. They have a long tradition in the history of ethno-nationalist paranoias. But above all, they have a history of recent and incessant activation by the political forces of the British two-party system over the last twenty years. In this respect, and as has already been indicated, Labour social democracy has left behind a uniformly toxic legacy since the 2000s, between the validation of the neo-Nazi British National Party’s “just concerns” in terms of the allocation of social housing and the lexicon of the “invasion” and “submersion” of the schools by the children of migrants and asylum seekers. This language has been promoted by ministers (Labour Home Secretaries) in office. In 2010, Labour’s election programme devoted a section to “crime and immigration: strengthening our territories, protecting our borders” to prepare “the next stage of national renewal”. In 2015, the merchandizing of the party’s conference offered mugs with the inscription: “Controls on immigration: I’m voting labour”.

This endless catalogue of nationalist and racist one-upmanship reached a new critical threshold when the Labour prime minister since June 2024, Sir Keir Starmer, a staunch Zionist and avowed supporter of the Palestinian genocide, hastened to express the first tribute to the American racist ideologue, Charlie Kirk. It should be noted that the condolences of Starmer and Kemi Badenoch (leader of the conservative opposition) also focused on the question of “freedom of expression” in the name of which openly racist and sexist remarks and the obscurantism that inspires them must have their place in the public debate (which cannot be applied to denunciations of the genocide and Palestinian solidarity, as we have had ample opportunity to understand).

In the aftermath of Kirk’s death, and on the eve of the “freedom of speech” demonstration called by Tommy Robinson, Badenoch declared: “The murder of Charlie Kirk is a blow to everything that Western civilization stands for: open, vigorous debate and peaceful protest.” For Boris Johnson, Kirk was nothing less than “a shining martyr for freedom of expression.”

Three weeks later, Badenoch announced the “hardest border closure plan Britain has ever seen,” which included withdrawal from the European Convention on Human Rights (ECHR) and the repeal of the Human Rights Act of 1998.

In this way, in Britain, the various shades of the far right can continue to content themselves with continuing and prospering the work of political formations that have long been hegemonic and are now both in the grip of a crisis of legitimacy of unprecedented gravity. The debt is therefore great to the Labour-Tory tandem, its multi-recidivist anti-foreigner legislation, its attacks on civil liberties, its “anti-woke” moral panic, its genocidal complicity and normalization.

This is perfectly reflected, among other things, in the mediocrity of these far-right propagandists. The exchange between Robinson and Musk, the interventions of Zemmour or Bystron have no rhetorical charm, not even the slightest danger, even, of any rhetorical charm. In this respect, 13 September carries with it the possibility of a pleasure in a nullity of which the imaginary of the “rape of our daughters and our sisters” could be an attempt at correction as sordid as it is desperate. At this point, perhaps it should be admitted, rhetorical brutality devoid of the slightest sophistication, of skill, is sufficient as a manifestation of the sheer desire for the use of force, while the Trumpist ICE militias, the fascist exaltation of Israeli genocidal power, or the giant riots and rabbles in Britain and now Ireland, show the future.
Tech, fossilism, armaments, Israelism and the heyday of neofascism

The rise of the British far right manifests itself in two obvious ways. The demonstration of 13 September is one of them; the considerable lead in opinion polls for Nigel Farage’s anti-immigration Reform UK party is another. Between Robinson and Farage is the false contradiction and the real complementarity that can exist between a delinquent-martyr who has long had no party other than his own online brand, and a notable determined to fit into an institutional framework within which he can claim to embody a majority succession.

The first, Robinson, won the support of Musk, who himself broke with Trump, to the detriment of the second, the billionaire having judged Farage too “weak” on the issue of immigration.

The official far right is now divided between Reform UK (Farage) and Advance UK, a split from Reform UK led by Ben Habib, joined by Robinson since August 2025. But at this stage, their nuances can be considered minor in view of the scale and continuity of the forces now engaged in supporting this new political configuration.

Robinson, whose audience and wealth are linked to social networks and his sales of “manifest” books, owes Musk for having regained his “freedom of expression” on a new X account, owned by Musk, whom he also thanked for the payment of legal costs (not confirmed by Musk himself).

But it is to Israelism, among the most fanatical, that the former British neo-Nazi, converted into a “free speech martyr”, frenzied Islamophobe and unconditional admirer of Israel (for which he has declared himself ready to fight in the event of war), owes a large part of his prosperity.

His sentence to thirteen months in prison for illegally filming and posting on Facebook the trial of Muslims accused of sexual assault (hence the banner of “free speech” against a woke justice system won over to the “migratory invasion”), earned Robinson an international far-right campaign “Free Tommy” (relayed by many Russian accounts as well as by Trump himself), with the support of the pro-Russian right,

Israeli-American Daniel Pipes’ ultra-Zionist Middle East Forum (MEF) paid for the legal costs and the organization of three demonstrations in support of Robinson at a cost of $60,000.

The Gatestone Institute, a pro-Israel think tank, and the David Horowitz Freedom Center, a far-right organization that describes itself as a “school of political warfare” against “the fifth column,” have published articles in defence of Robinson. In addition, the Gatestone Institute and the MEF both benefit from the largesse of Nina Rosenwald, co-president of a financial investment firm (American Securities Management), who claims to be an “ardent Zionist” and is known as the “sugar mama of anti-Muslim hate.”

Earlier, tech billionaire Robert Shillman, a regular donor to pro-Israel institutions, hired Robinson by the Canadian far-right organization Rebel Media in 2017-2018, awarding him a scholarship estimated at around $85,000 per year. This position was also accompanied by three assistant posts, each paid $2,500 per month. Robinson’s personal estate is estimated to be somewhere between £1 million and £3 million.

In October 2025, the verdict of a new trial was postponed following the official invitation extended to Robinson by the Israeli minister in charge of the diaspora and speaker of the Knesset, Amichai Chikli. There are many precedents of this kind, dating back to 2003 and the reception given by Ariel Sharon, then Prime Minister, to the neo-fascist Gianfranco Fini, an admirer of Mussolini and the apartheid wall then being built around the West Bank. However, the arrival of an influencer with no other title than that of an ex-Islamophobic hooligan is clearly a departure from the diplomatic decorum that was once de rigueur. The initiative, however, has sparked anger and incomprehension in Israel itself, and even in British Jewish community organizations, which are usually so loyal to Israel.
What place for Reform UK?

What about Reform UK and its leading figures? Farage, honorary chair, and Richard Tice, leader of Reform UK (which, unlike the other parties, has private company status), have distanced themselves from the “thug” Robinson. But like Robinson, Farage and Tice are the devoted and utterly servile relays of forces more determined than ever to do without standards and constraints that are far too cumbersome (fiscal, legal, environmental and so on), however weak or cosmetic they may be.

Farage (wealth estimated at between £3 million and £5 million) and Tice (£40 million and a tax-avoiding patriot), two authentic men of the people, both have their own programme on the conservative and Islamophobic channel, GB News, launched in 2021. In this context, both had plenty of time to challenge the reality of climate change, “absolute garbage,” according to Tice.

With this deep conviction, and for the good of all, the leaders of Reform UK defend the exploitation of Britain’s gas potential, knowing that “we’ve got potentially hundreds of billions of energy treasure in the form of shale gas,” according to Tice. It would then be “grossly financially negligent to a criminal degree to leave that value underground and not to extract it.”

Combining actions with words, Reform UK MPs, in council assemblies where they have won a number of majority positions since the last local elections, decided to repeal carbon neutrality targets and eliminate references to the “climate emergency” that have been integrated into the orientations of such assemblies in recent years. Budgets were then reallocated to other priorities, while continuing to receive subsidies earmarked for energy transition policies. Recently initiated guidelines and policies in the counties of Durham, Staffordshire, Kent, Derbyshire, and West Northamptonshire have been annulled.

But this determination in the denial of climate change and the derailment of the few existing efforts in terms of energy transition corresponds strictly to what could be expected from a “party” almost entirely in the hands of the fossil fuel industry. An investigation published in the New York Times in March 2025 showed that of the £4.75 million obtained in 2024 by Reform UK, 40% came from individuals known to have “openly disputed the reality of climate change, or from holders of investments in fossil fuels and other polluting industries”.

Other researchers have shown, for the DeSmog website, that between December 2019 and June 2024, Reform UK collected more than £2.3 million from oil and gas interests and climate sceptic figures, including, for example, Terence Mordaunt, director of the Global Warming Policy Foundation, an organization at the forefront of challenging work on climate science. This amount corresponded to 92% of total donations to the Reform UK business party. Most of these contributions also come from accounts registered in tax havens.

But the conflict of interest can be even more caricatural; Tice and Farage are employees of a chain, GB News, whose owner, Paul Marshall, owns £1.8 billion in shares in the fossil fuel sector, including Shell, Chevron, Equinor (Norway) and more than a hundred others. The DeSmog investigation also showed that in 2022, a third of GB News anchors had openly questioned climate work and half had denounced climate initiatives.

Reform UK is also the recipient of donations from an arms company, QinetiQ, which is a major beneficiary of the increase in state spending in the defence sector. “80% of QinetiQ’s revenues related to armaments come from British taxpayers alone,” according to the Byline Times, a windfall of public money which the company’s main shareholder, Christopher Harborne, redirects in part to the benefit of Reform UK, of which he is the main financier. Harborne donated nearly £14 million to Reform UK between 2019 and 2024, and paid for Farage’s two recent visits to Trump, in 2024 and 2025 at a total cost of nearly £60,000.

Between Robinson and Farage-Tice, we understand the whole issue and the meaning of “freedom of expression”: to maintain anti-migrant moral panics, by disrupting legal procedures if necessary, and to spread the myth of Islamization and the “rape” of the West; to be able to challenge climate research for the benefit of the fossil fuel lobby in the context of manifest conflicts of interest, and to defend all logics of oppression, up to the point of genocidal horror, by continuing to present oneself as a victim of feminist, anti-racist, or pro-Palestinian censorship, all in the service of the “freedom” of extraction, escape, exploitation, pollution and manipulation, conditions for the “expression” of an absolute capital.

Various components of the British far right could therefore be able to take over from the discredited parties, those who have made their bed but who still intend to ensure their survival with new anti-refugee, Islamophobic one-upmanship, and reformist sadism as proof of managerial credibility: the hell of cruelty and indifference inflicted on the children of Gaza comes from afar.

These are undoubtedly the symptoms of the transition from a decrepit parliamentary neoliberalism to the oligarchic order which is now on the way to reaching its full political fulfilment. In which case, it must be admitted, defending this indefensible requires a very great “freedom of expression”, purely fabricated, unencumbered by a justice system that is still capable of independence, a media and a press that are still free, scientific research that still assumes its critical vocation, and by any political demand for equality.

There is some good news, however, to emerge from the ongoing shipwreck of the parties that have dominated British political life until now: the deep, right-wing and sectarian Labourism, inspiring an almost universal disgust, may finally give a real chance to the emergence of a left-wing, socialist force, this time no longer condemned to the kind of peripheral and ephemeral agitation in which so much enthusiasm and momentum have inevitably ended up running out of steam and withering away until now. It remains to be seen, and to follow, the social democratic revival represented by the British Greens and, even more, what could become of Your Party, launched by MPs Jeremy Corbyn and Zarah Sultana, whose announcement alone during the summer received nearly a million messages of support and membership requests. Enough to do. Well, maybe.

A crew of tiny worms will be heading on a mission to the International Space Station in 2026 that will help scientists understand how humans can travel through space safely, using a Leicester-built space pod.

A team of scientists and engineers at Space Park Leicester, the University of Leicester’s pioneering £100 million science and innovation park, have designed and built a miniature space laboratory called a Petri Pod, based around the principle of the biological culture petri dish invented in 1887 and based upon earlier development work by the University of Exeter and Leicester, that will allow scientists on Earth to study biological organisms in space.

There is a burgeoning global drive for humans to colonise space, the Moon and other planets of our Solar System, but one of the challenges is the harmful effects of extended exposure to the effects of the space environment on human physiology. This includes microgravity which can lead to bone and muscle loss, fluid shift and vision problems in humans as well as radiation induced effects genetic damage, increased cancer risk, etc.

Hence life sciences experiments that investigate these effects on biology are an essential precursor to safe human space travel. The Fluorescent Deep Space Petri-Pod (FDSPP) has been developed by the Space Park Leicester team with the scientific lead Tim Etheridge at the University of Exeter and is tailored to the unique constraints of the space-based biology research that is urgently needed.

The Petri Pod is a miniaturised hardware solution for performing remotely operated biological experimentation on multiple types of organisms, via fluorescent and white light imaging capabilities in deep space. It is a self-contained experiment within a housing measuring approximately 10x10x30cm and weighing around 3kg, containing 12 Petri-Pods for experiments, four of which can be actively imaged. Each Petri Pod maintains a trapped volume of air and a stable comfortable temperature for the organisms when the unit is exposed to the vacuum of space. The worms are provided with food and water by means of an Agar carrier and the trapped air is sufficient for the small organisms involved. A more advanced version with ‘life support’ for larger and more complex organisms or extended missions is planned for the future based around the existing system.

The flight system hardware, along with a spare, has been delivered to the USA and has successfully undergone acceptance testing during the last two weeks, prior to it being launched on a cargo flight to the International Space Station (ISS) in April 2026. Its first passengers will be C-Elegans Nematode Worms which have natural fluorescent markers in their heads. These will be installed just before launch. Initially, the experiment and worms will spend time inside the ISS before being deployed outside on an experimental platform to expose the Petri Pod to the vacuum and radiation of space along with the micro-gravity environment for at least a 15-week period. The eight non-imaged ‘Petri Pods’ will contain a variety of other biological test subjects e.g., micro-organisms, along with tests of various materials. The experiment will be returned to Earth from the ISS after exposure on a future cargo return flight.

During the experiment the health of the worms will be monitored using photographic stills and time-lapse video captured with miniature cameras and by exposure to white light, or by fluorescent stimulation using low powered lasers, under the control of onboard microcontroller units. The FDSPP will collect data on temperature and pressure inside and outside of the containment volumes (‘Petri Pods’), and characterise the background radiation by monitoring accumulated radiation dose. Data will be stored locally in the unit for download on its return to Earth and also relayed to the Earth ground station over the ISS downlink communication system. The mission is enabled by funding from the UK Space Agency and commercial launch and support by Voyager Technologies based in Houston USA.

Professor Mark Sims who acted a project manager for FDSPP at Leicester said: “The Fluorescent Deep Space Petri-Pod has been engineered using the electronic, engineering, software and science expertise of the Space Park Leicester team, based around the 65-year heritage of space experiments at Leicester. This mission to the International Space Station (ISS) will demonstrate the flight-readiness of FDSPP and we believe its success will help position the UK amongst the global leaders of life sciences research on future low Earth orbit, Lunar and Mars missions planned by Space Agencies and private companies.”

Professor Tim Etheridge, the principal investigator and science lead for the experiment from the University of Exeter said: “Performing biology research in space comes with many challenges but is vital to humans safely living in space. This hardware, made possible through strong collaboration between biologists around the world and engineers at Space Park Leicester, will offer scientists a new way to understand and prevent health changes in deep space on any launch vehicle.”

Scientists get a first look at the innermost region of a white dwarf system



X-ray observations reveal surprising features of the dying star’s most energetic environment

Some 200 light years from Earth, the core of a dead star is circling a larger star in a macabre cosmic dance. The dead star is a type of white dwarf that exerts a powerful magnetic field as it pulls material from the larger star into a swirling, accreting disk. The spiraling pair is what’s known as an “intermediate polar” — a type of star system that gives off a complex pattern of intense radiation, including X-rays, as gas from the larger star falls onto the other one. 

Now, MIT astronomers have used an X-ray telescope in space to identify key features in the system’s innermost region — an extremely energetic environment that has been inaccessible to most telescopes until now. In an open-access study published in the Astrophysical Journal, the team reports using NASA’s Imaging X-ray Polarimetry Explorer (IXPE) to observe the intermediate polar, known as EX Hydrae. 

The team found a surprisingly high degree of X-ray polarization, which describes the direction of an X-ray wave’s electric field, as well as an unexpected direction of polarization in the X-rays coming from EX Hydrae. From these measurements, the researchers traced the X-rays back to their source in the system’s innermost region, close to the surface of the white dwarf. 

What’s more, they determined that the system’s X-rays were emitted from a column of white-hot material that the white dwarf was pulling in from its companion star. They estimate that this column is about 2,000 miles high — about half the radius of the white dwarf itself and much taller than what physicists had predicted for such a system. They also determined that the X-rays are reflected off the white dwarf’s surface before scattering into space — an effect that physicists suspected but hadn’t confirmed until now. 

The team’s results demonstrate that X-ray polarimetry can be an effective way to study extreme stellar environments such as the most energetic regions of an accreting white dwarf. 

“We showed that X-ray polarimetry can be used to make detailed measurements of the white dwarf's accretion geometry,” says Sean Gunderson, a postdoc in MIT’s Kavli Institute for Astrophysics and Space Research, who is the study’s lead author. “It opens the window into the possibility of making similar measurements of other types of accreting white dwarfs that also have never had predicted X-ray polarization signals.”

Gunderson’s MIT Kavli co-authors include graduate student Swati Ravi and research scientists Herman Marshall and David Huenemoerder, along with Dustin Swarm of the University of Iowa, Richard Ignace of East Tennessee State University, Yael Nazé of the University of Liège, and Pragati Pradhan of Embry Riddle Aeronautical University. 

A high-energy fountain

All forms of light, including X-rays, are influenced by electric and magnetic fields. Light travels in waves that wiggle, or oscillate, at right angles to the direction in which the light is traveling. External electric and magnetic fields can pull these oscillations in random directions. But when light interacts and bounces off a surface, it can become polarized, meaning that its vibrations tighten up in one direction. Polarized light, then, can be a way for scientists to trace the source of the light and discern some details about the source’s geometry. 

The IXPE space observatory is NASA’s first mission designed to study polarized X-rays that are emitted by extreme astrophysical objects. The spacecraft, which launched in 2021, orbits the Earth and records these polarized X-rays. Since launch, it has primarily focused on supernovae, black holes, and neutron stars. 

The new MIT study is the first to use IXPE to measure polarized X-rays from an intermediate polar — a smaller system compared to black holes and supernovas, that nevertheless is known to be a strong emitter of X-rays. 

“We started talking about how much polarization would be useful to get an idea of what’s happening in these types of systems, which most telescopes see as just a dot in their field of view,” Marshall says. 

An intermediate polar gets its name from the strength of the central white dwarf’s magnetic field. When this field is strong, the material from the companion star is directly pulled toward the white dwarf’s magnetic poles. When the field is very weak, the stellar material instead swirls around the dwarf in an accretion disk that eventually deposits matter directly onto the dwarf’s surface. 

In the case of an intermediate polar, physicists predict that material should fall in a complex sort of in-between pattern, forming an accretion disk that also gets pulled toward the white dwarf’s poles. The magnetic field should lift the disk of incoming material far upward, like a high-energy fountain, before the stellar debris falls toward the white dwarf’s magnetic poles, at speeds of millions of miles per hour, in what astronomers refer to as an “accretion curtain.” Physicists suspect that this falling material should run up against previously lifted material that is still falling toward the poles, creating a sort of traffic jam of gas. This pile-up of matter forms a column of colliding gas that is tens of millions of degrees Fahrenheit and should emit high-energy X-rays. 

An innermost picture

By measuring any polarized X-rays emitted by EX Hydrae, the team aimed to test the picture of intermediate polars that physicists had hypothesized. In January 2025, IXPE took a total of about 600,000 seconds, or about seven days’ worth, of X-ray measurements from the system. 

“With every X-ray that comes in from the source, you can measure the polarization direction,” Marshall explains. “You collect a lot of these, and they’re all at different angles and directions which you can average to get a preferred degree and direction of the polarization.”

Their measurements revealed an 8 percent polarization degree that was much higher than what scientists had predicted according to some theoretical models. From there, the researchers were able to confirm that the X-rays were indeed coming from the system’s column, and that this column is about 2,000 miles high. 

“If you were able to stand somewhat close to the white dwarf’s pole, you would see a column of gas stretching 2,000 miles into the sky, and then fanning outward,” Gunderson says. 

The team also measured the direction of EX Hydrae’s X-ray polarization, which they determined to be perpendicular to the white dwarf’s column of incoming gas. This was a sign that the X-rays emitted by the column were then bouncing off the white dwarf’s surface before traveling into space, and eventually into IXPE’s telescopes. 

“The thing that’s helpful about X-ray polarization is that it’s giving you a picture of the innermost, most energetic portion of this entire system,” Ravi says. “When we look through other telescopes, we don’t see any of this detail.” 

The team plans to apply X-ray polarization to study other accreting white dwarf systems, which could help scientists get a grasp on much larger cosmic phenomena. 

“There comes a point where so much material is falling onto the white dwarf from a companion star that the white dwarf can’t hold it anymore, the whole thing collapses and produces a type of supernova that’s observable throughout the universe, which can be used to figure out the size of the universe,” Marshall offers. “So understanding these white dwarf systems helps scientists understand the sources of those supernovae, and tells you about the ecology of the galaxy.”

This research was supported, in part, by NASA.

Comet sparks scientific fascination, online furor over ‘alien’ origins

A flying piece of cosmic rock or an alien threat? Comet 3I/ATLAS is hurtling through our solar system and captivating scientists and internet users alike, even prompting Kim Kardashian to ask NASA for answers.

Questions on whether the comet could actually be an alien spacecraft are coming from sources as varied as the reality TV star, a member of US Congress and a Harvard researcher, as well as from prominent conspiracy theorists.

But that theory has been shot down by NASA, which released new images of the comet on Wednesday after the speculation gained traction online.

“It’s amazing to see how people are really engaged in the discussion,” said Thomas Puzia, an astrophysicist who led the team at the Chilean observatory that made the discovery.

But, “it’s very dangerous and to a certain degree misleading to put speculations ahead of scientific process,” he told AFP in a thinly veiled criticism of another researcher who has been insisting for weeks that the extraterrestrial spacecraft hypothesis cannot be ruled out.

“The facts, all of them without exception, point to a normal object that is coming from the interstellar space to us,” he said.

He added the comet was “very exceptional in its nature, but it’s nothing that we cannot explain with physics.”

– Seeking signs of life –

Since its detection in July, the comet has generated intense speculation — unsurprisingly so, given it is only the third interstellar object foreign to our solar system ever discovered to be passing through.

The first was the Oumuamua comet, which sparked similar ripples of excitement and debate in 2017.

Even then, Harvard Professor Avi Loeb supported the theory that Oumuamua could be a spacecraft, a controversial position he later defended in a book.

He has now accused his scientific peers of lacking open-mindedness when it comes to Comet 3I/ATLAS.

“Obviously, it could be natural,” he told AFP. “But I said: we have to consider the possibility that it’s technological because if it is then the implications for humanity will be huge.”

NASA, however, did not agree.

“We want very much to find signs of life in the universe… but 3I/ATLAS is a comet,” said Amit Kshatriya, a senior NASA official, at a press conference on Wednesday.

The debate risked overshadowing the very real wonder that 3I/ATLAS represents, according to Puzia who said it offered “an unprecedented insight into an extrasolar system, potentially billions of years older than our own solar system.”

– ‘Goosebumps’ –

If there is one thing everyone agrees on, it is that 3I/ATLAS is anything but ordinary.

The comet holds many mysteries, particularly regarding its origin and exact composition, which scientists hope to unravel through close observation in the coming weeks as it gets closer to Earth.

This small, solid body composed of rock and ice from the far reaches of space could help us better understand how “planets might form” or even “how life might form around other stars in the Milky Way Galaxy in different times of the evolutionary history of the galaxy,” according to Puzia.

NASA scientist Tom Statler described having “goosebumps” when thinking about the comet’s origins.

“We can’t say this for sure, but the likelihood is it came from a solar system older than our own solar system itself,” he said. “It’s a window into the deep past, and so deep in the past that it predates even the formation of our Earth and our Sun.”

Unlike the two interstellar objects detected previously and only briefly studied, astronomers have had months to observe 3I/ATLAS.

And they hope this is just the beginning, thanks to improving technology for observation and detection.

“We should be finding many, many more of them every year,” Darryl Seligman of Michigan State University told AFP.

Theia and Earth were neighbors



New research suggests that the body that collided with Earth 4.5 billion years ago, creating the Moon, originated in the inner Solar System.

About 4.5 billion years ago, the most momentous event in the history of our planet occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly happened afterwards has not been conclusively clarified. What is certain, however, is that the size, composition, and orbit of the Earth changed as a result – and that the impact marked the birth of our constant companion in space, the Moon.

What kind of body was it that so dramatically altered the course of our planet's development? How big was Theia? What was it made of? And from which part of the Solar System did it hurtle toward Earth? Finding answers to these questions is difficult. After all, Theia was completely destroyed in the collision. Nevertheless, traces of it can still be found today, for example in the composition of present-day Earth and Moon. In the current study, published on November 20, 2025, in the journal Science, researchers led by the Max Planck Institute for Solar System Research (MPS) and the University of Chicago use this information to deduce the possible “list of ingredients” of Theia – and thus its place of origin.

The ratios in which certain metal isotopes are present in a body are particularly revealing. Isotopes are variants of the same element that differ only in the number of neutrons in their atomic nucleus – and thus in their weight. In the early Solar System, the isotopes of a given element were probably not evenly distributed: At the outer edge of the Solar System, for example, the isotopes occurred in a slightly different ratio than near the Sun. Information about the origin of its original building blocks is thus stored in the isotopic composition of a body.

Searching for traces of Theia in Earth and Moon

In the current study, the research team determined the ratio of different iron isotopes in Earth and Moon rocks with unprecedented precision. To this end, they examined 15 terrestrial rocks and six lunar samples that astronauts from the Apollo missions brought back to Earth. The result is hardly surprising: as earlier measurements of the isotope ratios of chromium, calcium, titanium, and zirconium had already shown, Earth and Moon are indistinguishable in this respect.

However, the great similarity does not allow any direct conclusions about Theia. There are simply too many possible collision scenarios. Although most models assume that the Moon was formed almost exclusively from material from Theia, it is also possible that it consists primarily of material from the early Earth's mantle or that the rocks from Earth and Theia mixed inseparably.

Reverse engineering of a planet

In order to learn more about Theia, the researchers applied a kind of reverse engineering for planets. Based on the matching isotope ratios in today's terrestrial and lunar rocks, the team played through which compositions and sizes of Theia and which composition of the early Earth could have led to this final state.

In their investigations, the researchers looked not only at iron isotopes, but also at those of chromium, molybdenum, and zirconium. The different elements give access to different phases of planetary formation.

Long before the devastating encounter with Theia, a kind of sorting process had taken place inside the early Earth. With the formation of the iron core, some elements such as iron and molybdenum accumulated there; they were afterwards largely absent from the rocky mantle. The iron found in the Earth's mantle today can therefore only have arrived after the core was formed, for example on board of Theia. Other elements such as zirconium, which did not sink into the core, document the entire history of our planet's formation.

Meteorites as a reference

Of the mathematically possible compositions of Theia and the early Earth that result from the calculations, some can be ruled out as implausible.

While the composition of the early Earth can be represented predominantly as a mixture of known meteorite classes, this is not the case with Theia. Different meteorite classes originated in different areas of the outer Solar System. They therefore serve as reference material for the building material that was available during the formation of the early Earth and Theia. In the case of Theia, however, previously unknown material may also have been involved. Researchers believe this material’s origin to be closer to the Sun than Earth. The calculations therefore suggest that Theia originated closer to the Sun than our planet.
