Object Wikipedia information

The Rosette Nebula is a large region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The cluster and nebula lie at a distance of some 5,200 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excite the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.
