Colliding Galaxies in Pisces: NGC 520 | Victor Blanco Telescope

Colliding Galaxies in Pisces: NGC 520 | Victor Blanco Telescope

A collision of two galaxies that began over 300 million years ago, NGC 520 is actually made up of a pair of disk galaxies. They will eventually merge to form a larger, more massive system. NGC 520 was discovered by William Herschel in 1784 and is one of the largest and brightest galaxies in the Siena Galaxy Atlas.
