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.
