A “jellyfish galaxy” with trailing tentacles of stars hangs in inky blackness on this picture from the NASA/ESA Hubble Area Telescope. As jellyfish galaxies transfer by means of intergalactic space, gasoline is slowly stripped away forming trails that resemble tendrils illuminated by clumps of star formation. These blue tendrils are seen under the core of this galaxy, giving it a jellyfish-like look. This specific jellyfish galaxy—referred to as JO201—lies within the constellation Cetus, which is known as after a sea monster from historical Greek mythology. This sea-monster-themed constellation provides to the nautical theme of this picture.
The tendrils of jellyfish galaxies lengthen past the intense disk of the galaxy’s core. This specific commentary comes from an investigation into the sizes, lots, and ages of clumps of star formation within the tendrils of jellyfish galaxies. Astronomers hope it will present a greater understanding of the connection between ram-pressure stripping—the method that creates the tendrils of jellyfish galaxies—and star formation.
Hubble’s Huge Discipline Digital camera 3 (WFC3) captured this galactic seascape. A flexible instrument that captures photographs at ultraviolet, infrared, and visible wavelengths, WFC3 is the supply of a few of Hubble’s most spectacular photographs.
