The bubble nebula is an emission nebula located in the constellation Cassiopeia.  At the center of the nebula is quite literally a bubble of gas being blown by the solar winds of bright star BD+60 2522 within the bubble and born from the gas of the nebula.  The growing bubble is currently about 10 light years across and is somewhat contained by the surrounding molecular cloud.  The nebula and molecular cloud are about 11,000 light years distant.
