Object data of Ced111

Object type: Reflection nebula
Size: 10'
Magnitude: -
Constellation: Cha
Distance: 500 Ly
Notes: Cederblad 111 is a blue reflection nebula embedded in Chamaeleon I, a nearby region of low mass star formation, located at a distance of 500 light years. The entire Chamaeleon I cloud covers an area of 5 square degrees and, at this distance, is one of the closest regions of star formation to the Earth.

The above image shows besides the blue reflection nebula also two deeply red Herbig-Haro objects: HH 49 and HH 50. These small patches of nebulosity are associated with newly born stars, and are formed when narrow jets of gas ejected by young stars collide with clouds of gas and dust nearby at speeds of several hundred kilometres per second.

The reddish nebula GN 11.07.3 can be found to the south east of Ced 111. This nebula is unusual in that it has no obvious illuminating star and its spectral energy distribution rises rapidly towards the infrared.
