CGE 1100 with .63 focal reducerDeveloped with IP3 and PS CS3 The nebula is 6 light-years wide and is expanding at 4 million miles per hour (7 million kilometers per hour). The nebula is 7,100 light-years from Earth in the constellation Cassiopeia.
Blown by the wind from a star, this tantalizing, ghostly apparition is cataloged as NGC 7635, but known simply as
The Bubble Nebula.
A fierce stellar wind and intense radiation from the star, which likely has a mass 10 to 20 times that of
the Sun, has blasted out the
structure of glowing gas against denser material in a surrounding molecular cloud. The intriguing Bubble Nebula lies a mere 11,000 light-years away toward the boastful constellation
Cassiopeia.
