The Bubble Nebula is a beautiful example
of gas being expelled into space by a giant star (center) about 40
times the mass of our sun. The bubble is not uniform, likely due to
its encounter with existing gas and dust of differing density. The gas
is expanding at 4 million miles per hour and is about 4 light years (24
trillion miles) across. The Bubble Nebula is in the constellation
Cassiopeia NGC 7635 and has the following statistics: RA: 23h 20m
40.0s, Dec: +61° 12' 00", Size: 16.0'x6.0', Class: E.
