πΈ UGC 1810: Wildly Interacting Galaxy from Hubble
Spiral galaxy UGC 1810 is colliding with a smaller companion, forming the interacting pair Arp 273. The bright blue outer ring is filled with young, massive stars triggered by gravitational forces. Located 300 million light-years away in Andromeda, UGC 1810 may one day absorb its partner.
