Arp 302 (also known as Exclamation Point Galaxy) is a galaxy in the constellation Boötes. Arp 302, also known as VV 340 or UGC 9618 consists of a pair of very gas-rich spiral galaxies in their early stages of interaction. An enormous amount of infrared light is radiated by the gas from massive stars that are forming at a rate similar to the most vigorous giant star-forming regions in our own Milky Way. Arp 302 is 450 million light-years away from Earth, and is the 302nd galaxy in Arp's Atlas of Peculiar Galaxies.
