THE BUBBLE NEBULA - NGC 7635

NGC 7635, also called the Bubble Nebula, is a H II region emission nebula in the constellation Cassiopeia .
The "bubble" is created by the stellar wind from a massive hot, 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.
It was discovered in 1787 by Friedrich Wilhelm Herschel
(FROM WIKIPEDIA)
