Bubble Nebula NGC 7635 My Beloved - Tumblr Posts

Sometimes, massive stars can blow bubbles. This image shows perhaps the most famous star-bubbles of all, NGC 7635, also known simply as The Bubble Nebula. Although it looks delicate, the 7-light-year diameter bubble offers evidence of violent processes at work. To the top left of the Bubble's center is a hot, O-type star, several hundred thousand times more luminous and 45-times more massive than the Sun. A fierce stellar wind and intense radiation from that star has blasted out the structure of glowing gas in a surrounding molecular cloud. The intriguing Bubble Nebula and associated cloud complex lie 7,100 light-years away toward the boastful constellation Cassiopeia. This sharp, tantalizing view of the cosmic bubble is a reprocessed composite of previously acquired Hubble Space Telescope image data.
