NGC2237 The Rosette Nebula in Monoceros


The Rosette Nebula is a vast cloud of dust and gas. In the heart of the Rosette Nebula lies a bright open cluster (NGC 2244) of stars that lights up the nebula. These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula's center, insulated by a layer of dust and hot gas. High energy light from the bright young stars of NGC 2244 ionizes the surrounding hydrogen gas clouds to create the red emission nebula appearance.A true diameter of the nebula is about 130 light years and distance 5 500 ly. The nebula is a splendid object, especially for astrophotography.
