NGC 7319 is a highly distorted barred spiral galaxy that is a member of the compact Stephan's Quintet[5] group located in the constellation Pegasus, some 311 megalight-years distant from the Milky Way.[1] The galaxy's arms, dust and gas have been highly disturbed as a result of the interaction with the other members of the Quintet. Nearly all of the neutral hydrogen has been stripped from this galaxy, most likely as a result of a collision with NGC 7320c some 100 million years ago.[6] A pair of long, parallel tidal tails extend southward from NGC 7319 in the direction of NGC 7320c, and is undergoing star formation.[7]
This is a type 2
One supernova has been observed in NGC 7319: On 19 August 1971, Leonida Rosino discovered SN 1971P (type unknown, mag. 16.8).[9]
