Caldwell 49 The Rosette Nebula

Image Of The Rosette Nebula

Caldwell 49 Rosette Nebula

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.

The image was captured on a very cold night ( 0 C, 32 F) camping at the Tierra Del Sol observatory site of the San Diego Astronomy Association.
