Arp 271

Arp 271 is a pair of similarly sized interacting spiral galaxies, NGC 5426 and NGC 5427. It is not certain whether the galaxies are going to eventually collide or not. They will continue interacting for tens of millions of years, creating new stars as a result of the mutual gravitational attraction between the galaxies, a pull seen in the bridge of stars already connecting the two. Located about 130 million light-years away, the Arp 271 pair is about 130,000 light-years across. It was originally discovered in 1785 by William Herschel. It is speculated,[3] [4] that the Milky Way will undergo a similar collision in about five billion years with the neighbouring Andromeda Galaxy, which is currently located about 2.6 million light-years away.[5]

gollark: Heavpoot == tux1 confirmed?
gollark: It's suspiciously similar to the heavpoot aesthetic.
gollark: I'm sure you'd like to think so.
gollark: This is incorrect, as all wikis are in fact mere projections or slices of WE.
gollark: False! gh0.pw is merely a subset of wiki encyclopaedia.
