UGC 1810: Wildly Interacting Galaxy from Hubble

This spiral galaxy, UGC 1810, is in an ongoing gravitational battle with its smaller galactic neighbor, creating a wildly interacting pair known as Arp 273. The featured galaxy's overall shape, especially its blue outer ring, is a direct result of these violent interactions. The blue color comes from massive, hot stars that have recently formed in the ring.
