The Bubble Nebula

The Bubble Nebula (aka NGC 7635) is an ]emission nebula in the constellation Cassiopeia. The “bubble” is created by the stellar wind from a massive, hot, young central star. Because the nebula is near a giant molecular cloud which contains its expansion, the bubble glows as a result of radiation from its central star.
