ARP245 Colliding Galaxies

ARP245 Colliding Galaxies

This isn’t the prettiest picture, but one of the more interesting. The two galaxies (NGC2992 and NGC2993) collectively referred to as ARP245 are in the throws of an epic galactic scale collision. Both galaxies are about 125 million years distant in the constellation Hydra.

The time period that these types of galactic collisions involve are on the order of billions of years. If you look closely you can see material being shared between the two galaxies.

The following link is a Youtube video showing a simulation of galaxy collisions with actual Hubble Telescope observations interlaced:
