NGC 520: Colliding Galaxies from Hubble

Is this one galaxy or two? The jumble of stars, gasoline, and dirt that is NGC 520 is now thought to consist of the remains of two separate disk galaxies. A defining ingredient of NGC 520 — as seen in enormous detail within the featured image from the Hubble Arena telescope — is its band of intricately interlaced mud working vertically down the spine of the colliding galaxies. A identical taking a judge collision might be anticipated in just a few billion years when our disk Milky Methodology galaxy to collides with our pleasant-disk galactic neighbor Andromeda (M31). The collision that defines NGC 520 began about 300 million years ago. Also is named Arp 157, NGC 520 lies about 100 million gentle years far away, spans about 100 thousand gentle years, and is also seen with a minute telescope in the direction of the constellation of the Fish (Pisces). Even though the speeds of stars in NGC 520 are instant, the distances are so pleasant that the struggling with pair will on no myth change its shape noticeably for the length of our lifetimes.
