Hubble captures two interacting galaxies in Arp 91
Original: Hubble image of Arp 91, also known as NGC 5953 and NGC 5954. NGC 5953, the large galaxy at center, and its companion NGC
The Hubble Space Telescope has imaged Arp 91, a pair of interacting galaxies about 100 million light-years away made up of NGC 5953 and NGC 5954. The picture shows the smaller NGC 5954 extending a spiral arm or tidal tail that visibly connects to its larger companion, clear evidence of gravitational interaction as the two galaxies slowly merge. Space enthusiasts are sharing the striking image widely.
Why now: Striking new astronomy imagery of galaxies merging naturally draws public attention and sharing.
