M52 and the Bubble Nebula ( NGC7635) in Cassiopeia

M52 and the Bubble Nebula ( NGC7635) in Cassiopeia

M52 in the upper left corner is an open star cluster and has about 200 members.
The nearby Bubble nebula is generated by a huge star, 40 times more massive than our sun. This star is so hot, that it sheds off its material very quickly. The dense gas surrounding the star shapes this material into a bubble. The nebula is approximatly 7100 light-years away.
