The Bubble Nebula is an emission Nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "Bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.
The Bubble Nebula was discovered in 1787 by William Herschel.
