| Designation | NGC 1313, Bennett 13 |
| Object type | Spiral galaxy |
| Coordinates | 03 h 18 min - 66° 30' Reticulum (Ret) |
| Description | In
visible light, NGC 1313 seems dominated by scattered patches of star
formation which give our picture a rather ragged appearance. The
clouds of bluish stars seem to have burst into existence at random,
without the normal trigger gravitational interaction or even a distinct
spiral to prompt them. Star formation seems to have occurred in a
series of irregular, self-sustaining bursts. However, a very
deep image shows that the outer parts of galaxy are also very
disturbed. Seen with a radio telescope, the galaxy is rich in hydrogen, the raw material of stars, and the gas circulates around the centre of the galaxy in a well ordered way, apparently hardly affected by the starburst activity or other irregularities that so colour our visual impression of this unusual galaxy. NGC 1313 is at a distance of about 15 million light years, close enough for some of its brightest stars to be seen as individuals. Entry from NGC 2000.0 (R.W.
