This picture is the central part of what is populary called the Heart Nebula. IC 1805 is an emmision nebula, and you can see emmisions from hydrogen (green), sulfer (red), and oxygen (blue). Also shown are hot star clusters also known as Melotte 15. The shape of the nebula is shaped by stellar winds and radiation from its star clusters.
The view spans about 15 light-years while the whole nebula is about 180 light-years across. The nebulae is found in the constellation Cassiopeia, which is about 7,500 light-years away in the Perseus arm of the galaxy.
