Globular Clusters
A spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers. The name of this category of star cluster is derived from the Latin globulus—a small sphere. A globular cluster is sometimes known more simply as a globular.
Bubble Nebula NGC 7635

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
