This is a younge star cluster only some 4 million years old.
Since they formed they are pushing the gas and dust from the
Rosette Nebula away, hence the clear 'hole'. They are in the
constellation Monoceros, not far from the Orion complex.
The name Rosette comes naturaly from the the shape of this nebula, that
of rose petals. Some 4,900 light years from earth, they are
considerably farther away from earth than M42 - almost 3 times as far!
We chose to bring out the different colors of red that this nebula has.
