OBJECT DESCRIPTION

The Rosetta Nebula is a complex of dust and gas that spans 50 light years across. It is quite big... more than 1 degree, and it covers the area of four Moons. The FOV in this picture is roughly 120 x 95 arcs minutes. We can see many NGC objects as 2237, 2238, 2239, and 2246. Inside the nebula, lies an open cluster of bright young stars designated as NGC 2244. The young stars recently formed from the nebula's material, and the brightest of which make the nebula shine by exciting its atoms to emit radiation. Star formation is still in progress in this vast cloud of interstellar matter.
