Rosette Nebula Widefield

The Rosette Nebula (NGC 2237) is an emission nebula located near one end of a giant molecular cloud in the constellation of Monoceros. It spans a distance of 100 ly and is located 5,000 ly from Earth.
At the centre of the nebula is NGC 2244, a group of stars that form a gravitationally bound open cluster thought to be about 4 million years old. These stars are emitting streams of charged particles carving out the gas and dust at the centre of the nebula.
