| Designation | NGC 2997, Bennett 41b |
| Object type | SBc class spiral galaxy |
| Coordinates | 09h46min -31°12' (Antlia) |
| Description | This highly enlarged field of 10 x 15 arcminutes - about one third the size of a first quarter moon - shows NGC 2997, a very nice mag 10.0 southern galaxy reminiscent of M 83 but with a disk that is inclined 45 degrees to our line of sight. The spiral arms are peppered with bright red blobs of ionized hydrogen where the bright blue stars are born that generate most of the light there. The nucleus shows interesting structure and concentrates an older population of yellowish stars. |
