The Cocoon Nebula (IC 5146) is a striking combination of emission, reflection, and dark nebulosity in the constellation Cygnus, sitting at the tip of a long dark dust lane (Barnard 168) that trails away from it across the sky. It surrounds and illuminates the young open cluster Collinder...

The Orion Nebula (M42, NGC 1976) is a diffuse emission nebula in the constellation Orion and the closest large region of massive star formation to Earth, at a distance of roughly 1,300-1,350 light-years. It is bright enough to be seen with the naked eye and spans about 25 light-years, powered by the intense ultraviolet radiation of the young Trapezium star cluster embedded at its heart. The nebula's...

The Heart Nebula is an emission nebula, 7,500 light-years (2,300 pc) away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. In 1958, it was identified as a radio source by Gart Westerhout and is therefore also referred to as Westerhout 4 . It displays glowing ionized hydrogen gas and darker dust lanes.
