Globular cluster
A globular cluster is 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.
Globular clusters, which are found in the halo of a galaxy, contain considerably more stars and are much older than the less dense galactic, or open clusters, which are found in the disk. Globular clusters are fairly common; there are about 150 to 158 currently known globular clusters in the Milky Way, with perhaps 10 to 20 more still undiscovered. These globular clusters orbit the Galaxy at radii of 40 kiloparsecs (130,000 light-years) or more. Larger galaxies can have more: Andromeda, for instance, may have as many as 500. Some giant elliptical galaxies, particularly those at the centers of galaxy clusters, such as M87, have as many as 13,000 globular clusters.

by: Kelley PolarI found her sleeping
And bound her up with roses
Did I know I held her life in my hands
Did I know I held her life in my hands
I whispered and she woke
I spoke the rosy ribbons
Did I know she held my life in her hands
And all round us was Elysion
Elysion
Elysion
The sea has drowned the city
The skies are full of thunder
Still I know I held her life in my hands
I shivered and she spoke
The final words of summer
Still I know, she held my life in her hands
And all around us was Elysion
Elysion
Elysion

I need you to hold on, when the sky is falling
I need you to hold on, when the sky is falling
I need you to hold on, when the sky is falling
