NGC7319 HSTWFC3

Stephan's Quintet This grouping of galaxies is located in the constellation Pegasus, about 280 million light-years from the Solar System. It was the first such compact group discovered and is also called Hickson Compact Group 92. 4 galaxies are physically connected and interacting: NGC 7318 A and B, NGC7319, and NGC7317 (and possibly NGC7320c). The brightest member of the group, NGC7320 is actually in the foreground closer to the Solar System The arms of NGC7319 spiral galaxy, at first seem well organized but in detail the spiral arms, dust and gas are disrupted, due to interaction with the other galaxies in the group. NGC7319 has had much neutral hydrogen stripped out of it into a long tail maybe due to a collision with NGC7320c (see Wide Field image above). Notice it exhibits little active star formation compared with the other members of the group
