NGC 2174 - The Rosette Nebula
The Rosette Nebula, also known as Caldwell 49, is an H II region
located near one end of a giant molecular cloud in the Monoceros
region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50)
is closely associated with the nebulosity, the stars of the cluster
having been formed from the nebula's matter.
The cluster and nebula lie at a distance of 5,000 light-years from
Earth and measure roughly 130 light years in diameter. The radiation
from the young stars excites 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.
