Designation |
IC 2948 and part of IC 2944 (The
Running Chicken cluster) |
Constellation |
Centaurus (Cen) |
Description |
Dark clouds, like these Bok
Globules, were once thought to be holes in the sky. In fact, the
extinction caused by their dust particles blocks the light from the
emission nebula behind. A close-up of the group at center can be found here. The field of view of 45 x 30 arcmin is centered on the
intersection between the cluster IC 2944 and the very active nebula IC 2948 at declination - 63°20'. There is also a view
in color of the same field. |
