Bubble Nebula
Formed by the stellar wind from a massive, hot star plowing into denser surrounding material. Because the gaseous density is greater to the NE (top left) than the SW (bottom right), the wind progresses less to the NE and further to the SW, offsetting the location of the star within the bubble. It is located in the upper part of the bubble and slightly to the left in this image.
