ESO 373-8

ESO 373-8 is a spiral galaxy located about 25 million light years away and is part of the NGC 2997 group, along with at least 7 other nearby galaxies. From Earth, it is seen as only a thin disk, its spiral shape facing an angle away from us.

When galaxies form, they spin more slowly, but as they collapse in on themselves this rotation speeds up due to the conservation of angular momentum. Think about spinning in a chair- if you pull your arms in, you spin faster. This is the same for galaxies- as they condense, their rotation increases. As they rotate faster, material is pulled into a flat disk, like spinning pizza dough. This causes spiral galaxies to form the thin, flat disks we are familiar with.
