Rosette Nebula - NGC 2237
The Rosette Nebula is a faint emission nebula in the constellation Monoceros. It lies at a distance of approximately 5200 light years and is about 130 light years in diameter. This cloud of gas glows in the red light characteristic of ionized hydrogen as it recombines with lost electrons. The open star cluster NGC 2244 (Caldwell 50) is located at the center of the nebula.
