Amazingly powerful stellar winds created by Wolf-Rayet star BD +60°2522 have helped create this most beautiful bubble of compressed gas. This star
is estimated to be at least 40 times more massive than our sun and hundreds of thousands of times more luminous. Less than 300 of these stars are known to exist in our galaxy. They are capable of
producing stellar winds in excess of 1500 kilometers/second.
NGC 7635, otherwise known as the Bubble Nebula, can be found midway between the constellations of Cepheus and Cassiopeia in the northern skies and lies embedded in the surrounding HII region
Sharpless 162. This gas bubble is one of the most photographed targets in the evening sky. The bubble is estimated to be about 6 light years in diameter.
