Arp 273

In this April 20, 2011 photo provided by NASA, the Hubble Space Telescope captures a group of interacting galaxies called Arp 273. The larger of the spiral galaxies, known as UGC 1810, has a disk that is tidally distorted into a rose-like shape by the gravitational tidal pull of the companion galaxy below it, known as UGC 1813. A swath of blue jewels across the top is the combined light from clusters of intensely bright and hot young blue stars. The smaller, nearly edge-on companion shows distinct signs of intense star formation at its nucleus, perhaps triggered by the encounter with the companion galaxy. A series of uncommon spiral patterns in the large galaxy is a tell-tale sign of interaction. Arp 273 lies in the constellation Andromeda and is roughly 300 million light-years away from Earth. Hubble was launched April 24, 1990, aboard Discovery's STS-31 mission. (AP Photo/NASA)
