Rosette Nebula NGC 2237

This rose-like cloud of cosmic dust is known as the Rosette Nebula. Its round shape has been sculpted by the winds and radiation coming from the cluster of hot young stars at its centre.

Clearly visible are various dark dust sculptures called Bok globules, silhouetted against the background nebulosity. Left alone long enough, they would likely form stars and planets.
