描述

Also known as M90 or Messier 90, this spiral galaxy exhibits less star formation than usual due to a phenomenon called ram pressure stripping. Gas that could have collapsed to form stars was instead stripped away as the galaxy moved through the intracluster medium between galaxies. Space may be mostly empty, but a galaxy moving fast enough through it can feel it.

This galaxy was observed as part of the wonderful PHANGS-HST. archive.stsci.edu/proposal_search.php?mission=hst&id=...
