Sharpless 308: Star Bubble

Sharpless 308: Star Bubble
Blown by fast winds from a hot, massive star, this cosmic bubble is huge. Cataloged as Sharpless 2-308 it lies some 5,200 light-years away toward the constellation of the Big Dog (Canis Major).That corresponds to a diameter of 60 light-years at its estimated distance. The massive star that created the bubble, a Wolf-Rayet star, is the bright one near the center of the nebula. Wolf-Rayet stars have over 20 times the mass of the Sun and are thought to be in a brief, pre-supernova phase of massive star evolution. Fast winds from this Wolf-Rayet star create the bubble-shaped nebula as they sweep up slower moving material from an earlier phase of evolution. The windblown nebula has an age of about 70,000 years. Relatively faint emission captured in the expansive image is dominated by the glow of ionized oxygen atoms mapped to a blue hue. This is what happen at the end of our Sun lifetime. But these stars Wolf-Rayet star do it when they are young.These massive star life bright and active lives and die young. These stars have lifespans of just of just few billion years compare to our Sun about 9 billion and red dwarf stars might last until the end of the universe.They would be the last stars to die and the universe is full of these low mass red stars.With solar wind that are fly off at great speed they mayn't be any earth size planet with atmosphere and the Jupiter size planet might look like a comet with some of its atmosphere being blow away but with the size of Jupiter it could hold up to 90% of its atmosphere.
