Arp 273 is a group of galaxies which interact with each other. The constellation is 300 million light years away from Earth in the constellation Andromeda. The Andromeda galaxy is also located in the Andromeda constellation. The larger of the spiral galaxies, known as UGC 1810, is about five times more massive than the smaller galaxy, known as UGC 1813. The force of gravity has shaped the larger galaxy into a rose-like shape by the gravitational pull of its smaller companion galaxy below it. It is believed the smaller galaxy has actually passed through the larger galaxy at a distant point in our universe’s past. The smaller galaxy also shows signs of active star formation at its nucleus.
