In visible light, this galaxy looks like a jellyfish with blue "tentacles" of young stars dangling from its disk. In X-ray light, a giant tail of hot gas streams behind the galaxy. Infrared will study this tail of gas & the stars forming in it.
The spiral galaxy ESO 137-001 is an example of a “jellyfish” galaxy, because blue tendrils of star formation stream away from it like jellyfish tentacles. NASA’s Webb Space Telescope will study those sites of star formation to learn more about conditions there. Credits: NASA, ESA
