The Rosette Nebula: NGC 2237 or Caldwell 49

 

The Rosette Nebula (NGC 2237) in our own Milky Way galaxy is about 100 light years wide and 5000 light years distant. Inside this beautiful emission nebula is an open cluster of bright young stars that formed about three million years ago from the nebular dust and gas; their stellar winds are clearing a hole in the nebula's center. The Rosette is part of a wider molecular cloud containing enough gas and dust to give birth to over 100,000 suns. Ultraviolet light from the hot stars in the center causes the nebula to glow. Robert Gendler: APOD Feb. 14, 2007; pg. 216 in You and the Universe.
