Arp 302 (also known asExclamation Point Galaxy) is agalaxy in the constellationBoötes. Arp 302, also known asVV 340 or UGC 9618 consists of a pair of very gas-richspiral galaxies in their early stages ofinteraction. An enormous amount ofinfrared light is radiated by the gas from massivestars that are forming at a rate similar to the most vigorous giantstar-forming regions in our ownMilky Way. Arp 302 is 450 million light-years away from Earth, and is the 302nd galaxy in Arp'sAtlas of Peculiar Galaxies.
