Bubble Nebula - NGC 7635

You'd be forgiven for thinking it's a planetary nebula, particularly given it's shape, neither is it a supernova remnant blasting a hole in a nebulous area, although that's a little closer.

In fact, this is an O type star blasting out a huge 7 light year wide bubble through it's stellar winds, you can see the star just offset from what appears to be the middle.

The structure is seen only because the UV light bombarding the gas and dust, making it glow, although the same effect is seen throughout the full structure of dust and gas, found almost 8,000 light years from us in the constellation of Cassiopia.

Ridges of glowing interstellar gas and dark dust clouds inhabit the turbulent Lagoon Nebula. Also known as M8, The bright star forming region is about 5,000 light-years away. It makes for a popular stop on telescopic tours of the constellation Sagittarius which lies toward the center of our Milky Way Galaxy. It is dominated by the red emission of ionized hydrogen atoms that are recombining with stripped electrons. This view of the Lagoon's central region reaches about 40 light-years across. The bright hourglass shape near the center of the frame is gas ionized by radiation and extreme stellar winds from a massive young star.
