About the Object

Located about 130 million light-years away in the constellation Cepheus, NGC2276 and NGC2300 showcase a fascinating examples of galactic interaction in the nearby universe. NGC 2276 is a distorted spiral galaxy of type SBc whose asymmetric appearance, compressed western arm, and enhanced star formation are thought to result from its close encounter with the massive elliptical galaxy NGC 2300, exhibiting shells in the outer regions. The system is cataloged twice in Chip Arp's famous Atlas of Peculiar Galaxies: Arp 25 highlights the unusual one-armed morphology of NGC 2276, while Arp 114 refers to the interacting pair as a whole. The image also reveal a rich background populated by a fair number of more distant galaxies.
