NASA / ESA’s Hubble Space Telescope observes a massive galactic sea creature located over 700 million light-years from Earth. JO206 is a colorful star-forming disk surrounded by a pale, luminous cloud of dust, while a cluster of bright stars with crisscross diffraction spikes stands out in the foreground against an blotchy black backdrop.
At the bottom right of this image, you can see long tendrils of bright star formation trail the disk of jellyfish galaxy JO206, similar to how their real-life counterpart trails tentacles behind them. Their tendrils are formed by the interaction between galaxies and the intra-cluster medium, a tenuous superheated plasma that pervades galaxy clusters.

Surprisingly, Hubble revealed that there are no striking differences between star formation in the disks of jellyfish galaxies and star formation in their tentacles, which suggests the environment of newly formed stars has only a minor influence on their formation,” according to NASA.
