M27: The Dumbbell Nebula!
M27 is one of the brightest planetary nebulae on the sky, and can be seen toward the constellation of the Fox with binoculars. Spotted by Charles Messier in 1764, M27 was the first planetary nebula ever discovered .
The nebula forms as the star's outer layers are expelled into space, with a visible glow generated by atoms excited by the dying star's intense but invisible ultraviolet light. - 3 hours ago
