Another Early Universe Surprise From The JWST: A Jellyfish Galaxy

belaUniverse Today4 hours ago4 Views

This is the spiral galaxy ESO 137-001, the first Jellyfish Galaxy discovered. Ram pressure has stripped some of its gas and stretched into long filaments that dangle in one direction like jellyfish tentacles. Now astronomers have discovered another candidate jellyfish galaxy, but this one appears much earlier in the Universe, surprising astronomers.

Astronomers have found a candidate Jellyfish Galaxy only about 5 billion years after the Big Bang. This is earlier than expected, since the ram pressure stripping responsible for it wasn’t thought to be possible so early in the Universe’s history. The galaxy could explain the puzzling “Red Nugget” galaxies, but first it has to be confirmed.
