NGC7635 - The Bubble Nebula
Wed Sep 20 2023
The Bubble Nebula is exactly what it sounds like, a nearly perfect sphere of gas about seven light-years across, blown into space by the fierce wind of a single massive, hot star. That star is many times more massive than our Sun, and its relentless outflow pushes against the surrounding cloud to inflate this delicate cosmic bubble.
