Bubble Nebula region

The Bubble Nebula (NGC7635) is seen here with Messier 52 "the Scorpion" open cluster. Also shown are S 158 (left) and NGC7538 (lower left).

The entire region is part of a large macro cloud showing strong HII emissions. The Bubble itself is formed by the strong solar winds of a large star within the bubble. These winds apply a force against the surrounding dust & gases forming a bubble like structure.
