COMMENTS ON THE PHOTO:
NGC 7635, also known as the Bubble Nebula, is a nebula about 10 light-years across in the constellation Cassiopeia, near the open cluster Messier 52. It is formed by the stellar wind created by the star SAO 20575 (BD+60 2522) at a speed of more than 1,700 km/s. This star, which is eccentric to the cloud, is the brightest. It is very young (less than 4 million years), very hot (around 35,000 degrees) and massive (20 to 40 times the mass of the Sun). The star is not at the centre, as the expanding cloud encounters a denser and cooler region on one side. It is expected to explode as a supernova in 10 to 20 million years.
