Name: Rosette Nebula - NGC 2237 -  Distance  5,200 Light Years  - In the Constellation  Monoceros.

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.
