Description: The central object in this image is aptly nicknamed 'The Bubble Nebula'. The hot, young central star (Wolf-Rayet type) is ejecting a stellar wind which has carved out a roughly spherical cavity in the surrounding ionized hydrogen. The Bubble contains several solar masses of ionized gas. The larger surrounding emission region is known as Sharpless 162.

Close-up views of The Bubble Nebula are available on this site in color and Ha.
