A "jellyfish galaxy" with trailing tentacles of stars hangs in inky blackness in this image from the NASA/ESA Hubble Space Telescope. As jellyfish galaxies move through intergalactic space, gas is slowly stripped away forming trails that resemble tendrils illuminated by clumps of star formation. These blue tendrils are visible below the core of this galaxy, giving it a jellyfish-like appearance. This particular jellyfish galaxy—known as JO201—lies in the constellation Cetus, which is named after a sea monster from ancient Greek mythology. This sea-monster-themed constellation adds to the nautical theme of this image.
