M-27, The Dumbell Nebula in Vulpecula

Dave O'Toole M-27 image, binned (320x240)

M-27 is one of the more well known examples of a planetary nebula. A planetary nebula is formed when a dying star throws off its outermost layers due to internal force imbalances. The gas extends outward into space and is illuminated by the slowly-cooling remains of the star. It is thought that our sun will form a planetary nebula like this at end of its days. M-27 is estimated to be 812 light years away.
