—via cwnl

Distance: 7,800 Light Years

Imagine a star 40 times as massive and several hundred thousand times more luminous than our sun? Well, BD +60°2522 is such a star. It’s enormous energy output and powerful stellar winds have blown a titanic bubble of ionized gas measuring 6 light years in diameter. Popularly known as the Bubble Nebula, the strange symmetrically round nebula is the outcome of the prodigious energy output and fierce stellar winds of an unusually powerful star known as a Wolf-Rayet star. Named after the French astronomers Charles Wolf and Georges Rayet
