Melotte 15 is the open star cluster at the heart of IC 1805. It's radiation causes the surrounding nebula to glow.
The cluster contains very young, blue, hot supergiant stars about 1.5 million years old. It is located near the nebula’s centre and home to several bright stars with a mass almost 50
times that of the Sun, as well as many faint stars far less massive than the Sun. Melotte 15 once contained a microquasar, a radio emitting X-ray binary system, but the system was expelled
from the cluster millions of years ago.
