A Meteor That Lit Up Ontario Skies This Week Came All The Way From Beyond Mars (VIDEO)
It even changed colours as it streaked across the sky.

Parts of the province got an otherworldly visitor that flashed across the dark sky and it had a long journey to get there. A meteor over Ontario came all the way from the asteroid belt which is beyond Mars. Videos and pictures of the space object streaking through the night are spectacular.

If you were in southern Ontario on January 21 and looked up just before 9:00 p.m. you might have seen a bright light streak across the night sky.

That was a meteor fireball that was likely the size of a softball.

It flashed overhead just to the north of Goderich and was spotted by people from hundreds of kilometres away.

Reports about the fireball were sent in from southern Ontario, Michigan, Wisconsin, New York and Ohio.

Peter Brown, a meteor scientist from Western University, posted videos on Twitter of the celestial object lighting up the sky.

This visitor from outer space lit up about 80 kilometres above the ground and started just east of the Ontario town.

It eventually fizzled out north of the town, about 30 kilometres above Lake Huron.

Based on the path it took through the atmosphere, Brown was able to trace its origin back to the asteroid belt which is just beyond Mars.

If any small meteorites actually fell from the sky, they likely ended up in the lake

A meteor is a streak of light across the sky that happens when space rocks, known as "meteoroids" enter Earth's atmosphere.

Since this flash was intense enough to rival the brightness of Venus, it's called a fireball.

Usually, cameras set up to shoot events like this only capture black and white but two of them actually caught this streak changing colours as it flashed through the sky.

In both photos, you can see the fireball change from red to white to blue and back to red again.

The colour of the space rock could be based on what it's made of, the flow of air around it, the speed it travelled at or how it broke apart.

The asteroid belt is between 179.5 and 329 million kilometres away from Earth.

So this little guy travelled a long way to flash across the sky over southern Ontario.


Fireball ‘as bright as the moon’ lands in Lake Huron

A fast, bright burst of what were probably softball-size meteors caught the attention of our Canadian neighbors earlier this week, before likely arcing down to land in Lake Huron.

While it wasn’t seen by too many sky-watchers on the U.S. side of Lake Huron, observatories in Canada, including Western University in London, Ontario, captured an image of the fireball last Tuesday night. It likely was a collection of small meteors grouped together, researchers say, according to CTV News in Canada.,

Spotters say the fireballs looked “as bright as the moon” as they whizzed across the sky.

In a Reddit discussion titled “orange fireball in night sky," a handful of people talked about seeing the fireball overhead.

“Anyone see this incredible sight around 9:10 pm in the sky north of London? An orange fireball streaming across the sky," one person wrote.

“Yes!!! Saw it driving home a few minutes ago. I’ve never seen anything like it before!,” another person posted.

Others who saw it chimed in:

“Yes! Omg my husband and I saw this. We were near Masonville mall! It was so bright. I’ve never seen anything like that. With I had a dash cam to capture it.”

“Was sitting at Carey’s and I saw it for a split second. Buddies thought I was nuts. Was cool though.”

“Yeah we saw it on a walk last night. It was around 9. Wonderland and Oxford area. It was tracking north fairly slowly. Saw the white ball, orange tail, and even saw some bits breaking off of it.”

Peter Brown, a professor in Western University’s physics and astronomy department, tweeted a series of photos of the spectacle. He dubbed it the Kintail fireball, for the spot near the Canadian shoreline of Lake Huron where it was believed to have crossed over before going into the water. On a map, Kintail is directly across the lake from Michigan’s Thumb.

“Kintail fireball orbit from last night place origins firmly from the asteroid belt. The initial mass was somewhere between a few to ten kilograms - softball sized. Not quite as bright as the full moon," Brown posted on Twitter.

Fireballs are born when particles of meteors hit the Earth’s atmosphere and burn their way across the sky.

There were some reports of this particular fireball from U.S. sky watchers. These came from people in Port Huron, Flint and St. Clair Shores in Michigan, and other spots in Ohio and New York, as reported to the American Meteor Society.

Fireball recorded in Huron County

Video cameras from Western University captured a fireball in Huron County Thursday night.

UWO Meteor Scientist Peter Brown tweeted several images and videos of the fireball.

He reported that the fireball started near Brussels and ended just offshore over Lake Huron near Kintail.

He said a low velocity and an end height of 33 kilometres suggests small meteorites may have landed, likely in Lake Huron.

Bright meteor over southern Ontario traced back to the asteroid belt

Friday, January 24th 2020, 12:30 pm - Did you see this fireball?


At just before 9 p.m., on the night of Tuesday, January 21, 2020, southern Ontario had an unexpected visitor - a hunk of rock from space that blazed through the sky as a meteor fireball.


The meteor, which flashed overhead just to the north of Goderich, ON, was spotted from hundreds of kilometres around. The American Meteor Society received over 30 reports from various locations around southern Ontario and southern Michigan, and as far away as Sheboygan, Wisconsin, Rochester, New York, and Columbus, Ohio

According to Dr. Peter Brown, from the University of Western Ontario's Meteor Group, the meteoroid that caused this fireball was likely the size of a softball, so perhaps 10 centimetres wide, with a mass of up to 10 kilograms, and it was travelling at around 15 kilometres per second (54,000 km/h).

As Brown posted to Twitter, the fireball flared to life roughly 80 kilometres above the ground, starting about 50 kilometres east of Goderich, and it winked out around 30 kilometres above the ground, somewhere over the waters of Lake Huron, west of Kintail.

From the path it took during its steep plunge through the atmosphere, Brown was able to trace the meteoroid back to its origin in the asteroid belt, beyond Mars.

Given the speed of this meteoroid and the height where the fireball ended, Brown said that small meteorites may have landed from this event. Unfortunately, since the end point of the fireball was over the water, any meteorites that did reach the surface are now likely lying at the bottom of Lake Huron

Meteors are flashes of light, resulting from the passage of some object from space - a meteoroid - travelling at high speed through the atmosphere. As the meteoroid - whether it's a speck of dust, an ice crystal or a chunk of rock or iron - flies through the air, it compresses the air molecules directly in its path, causing them to heat up until they glow. 


Any meteor flash that is intense enough to rival the brightness of Venus is typically called a fireball. If the fireball includes a sudden, intense flash due to the meteoroid breaking apart, it is often called a bolide.

Although most meteor cameras simply capture in black and white, two cameras that caught the Kintail meteor managed to pick up colours as the meteor flashed overhead.

As shown above, the meteor camera at Elginfield Observatory caught the meteor flashing from red to white to blue and back to red.

According to Brown, it is possible to tell something about the composition of a meteoroid based on the colour of the meteor flash it produces. However, the meteor colour can also be influenced by the flow of air around the meteoroid, the speed at which it was travelling, and even how the meteoroid broke apart. So, without actually recovering pieces of it, or having a detailed spectrum from the light to examine, there's no telling exactly what is causing the colours.

Did you see this fireball? Submit a report to the American Meteor Society.
