NGC 7635 Bubble Nebula

The Bubble Nebula also known as NGC 7635 is located in the constellation Cassiopeia roughly 7,000 light-years from Earth. The nebula was discovered in 1787 by British astronomer William Herschel. The star responsible for the creation of this nebula is 45 times more massive than our sun and the gases from the star become extremely hot causing them to escape as stellar winds creating this bubble.
