| Notes | The Bubble Nebula, NGC 7635, marks the boundary between material propelled outward by intense stellar winds from a hot, massive star buried within the bubble meeting the denser and cooler gas of the surrounding nebula. The stellar wind, with a velocity of about 4 million miles per hour, has formed this 6 light year diameter structure we know as the Bubble Nebula, which lies abut 7100 light years from earth. M 52 is the rich, open cluster in the upper left corner of the image. Its estimated distance from earth is 5000 light years, spanning some 19 light years from end to end. |
