Description and Details:
A magnificent emission nebula located in the constellation Cassiopeia.
Situated approximately 6,500 to 7,500 light-years from Earth, it spans about 200 light-years in diameter. At the center of the nebula lies the open cluster Melotte 15, which contains young, massive, and very hot stars. Their intense radiation and stellar winds sculpt the surrounding clouds of gas and dust.
