Rosette Nebula

In astronomy, the Rosette Nebula is a large, circular emission nebula located near one end of a giant molecular cloud in the Monoceros constellation.

It is believed that stellar winds from a group of O and B stars are exerting pressure on interstellar clouds to cause compression, followed by star formation in the nebula.

The Rosette Nebula has an angular diameter of 1.3° and lies some 900 parsecs or 3000 light years from Earth's Solar System.
