What is JO201?

 Feb 28, 2023   Admin

The Hubble Space Telescope recently captured an image of JO201, a jellyfish galaxy in the Abell 85 galaxy cluster.

About JO201:

  • It is a jellyfish galaxy which lies in Abell 85 galaxy cluster.
  • It is at a distance of about 700 million lightyears, in the constellation of Cetus or the Whale.
  • What are jellyfish galaxies?

  • They are a type of galaxy that exhibit long “tentacles” or “tails” of gas, dust, and stars that appear to be streaming away from the galaxy’s main body.
  • These tentacles are formed as the galaxy moves rapidly through the hot gas of a galaxy cluster, causing the gas to strip away from the galaxy and form a tail. This process is called ram-pressure stripping.
  • The tendrils of jellyfish galaxies extend beyond the bright disc of the galaxy's core.
  • What are Galaxy clusters?

  • They are the largest objects in the universe that are held together by their own gravity.
  • They contain hundreds or thousands of galaxies, lots of hot plasma, and a large amount of invisible dark matter.
  • Galaxy clusters are home to the biggest galaxies in the known universe and provide us with information about the structure of the universe on the largest scales.
