Astrophotography by Eddie Guscott
The Bubble Nebula gets it's name from the obvious bubble shape seen at the centre of the nebula. Located in the constellation of Cassiopeia, this emission nebula lies about a half degree from the open cluster M52. The central area (the bubble) is actually a massive outflow from a Wolf-Rayet star (the brightest star in the bubble) and is ionised by the energetic starlight. The bubble itself is estimated to be about 10 light years in diameter at a distance of 7100 light years.
