Cep OB 3b
Cep OB 3b is a cluster in the northern constellation of Cepheus. It is similar in some ways to the famous cluster found in the Orion Nebula. But unlike the Orion Nebula, there is relatively little dust and gas obscuring our view of Cep OB 3b. Its massive, hot stars have blown out cavities in the gaseous cloud with their intense ultraviolet radiation which mercilessly destroys everything in its path. Cep OB 3b may show us what the Orion Nebular Cluster will look like in the future.
