James Webb Telescope Discovers Distant Jellyfish Galaxy with Star Formation Astronomers using the James Webb Space Telescope (JWST) have identified the most distant jellyfish galaxy ever observed. This galaxy, located 8.5 billion light-years away, exhibits long, flowing trails of gas and newly formed stars, which is characteristic of jellyfish galaxies. These unusual galaxies move through galaxy clusters filled with hot gas, which causes their gas to be stripped off, forming long, tentacle-like trails. This phenomenon is called ram-pressure stripping. The galaxy was found in the COSMOS field, a region that has been extensively studied by multiple telescopes. This discovery offers a rare glimpse into the early universe, revealing a more violent and turbulent environment than previously thought. The discovery challenges earlier assumptions that galaxy clusters at this time were still forming and that such stripping was uncommon. The presence of young stars forming in the stripped gas also offers valuable insight into galaxy evolution. Researchers hope to observe this galaxy further with the JWST to deepen their understanding of galaxy transformations in the early universe.

A galaxy with a long tail (middle), as well as other galaxies and some lensed galaxies.

There is even a jellyfish galaxy. Those galaxy with long tail that move trough the cluster at higher speed, stripping the galaxy of gas. The tail then forms new stars. #jellyfishgalaxy

Jellyfish Galaxy Sheds Spiral Arms in “Bunny Ear” Tails Astronomers have imaged a "jellyfish" galaxy in detail, revealing that its spiral arms now drag behind it as a pair of tails.
