The Bubble Nebula, also known as NGC 7635, or Caldwell 11, is located in the constellation Cassiopeia. The "bubble" is created by the stellar wind from a massive hot, central star, SAO 20575. 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.
Size: 7 light-years across (A light year is roughly 6 trillion miles)
