Another #JellyfishGalaxies image from the NASA/ESA Hubble Space Telescope, this time JO206 with a colourful star-forming disc surrounded by a pale, luminous cloud of dust: https://esahubble.org/images/potw2323a/ - jellyfish galaxies are so-called because of their resemblance to their aquatic namesakes; the tendrils of jellyfish galaxies are formed by the interaction between galaxies and the intra-cluster medium, a tenuous superheated plasma that pervades galaxy clusters.

"Star-forming, Hα-emitting clumps are found embedded in the gaseous tails of galaxies undergoing intense ram-pressure stripping in galaxy clusters, so-called #jellyfish #galaxies. [...] We obtained UVIS/HST data to observe the first statistical sample of clumps in the tails and disks of six #jellyfishgalaxies": https://arxiv.org/abs/2301.08279
