Messier 56 (also known as M56 or NGC 6779) is a globular cluster in the constellation Lyra. [a] It was discovered by Charles Messier in 1779.[b] It is angularly found about midway between Albireo (Beta (β) Cygni) and Sulafat (Gamma (γ) Lyrae).
NGC 6355 is a globular cluster located in the constellation Ophiuchus. [5] It is at a distance of 28,000 light years away from Earth, and is currently part of the Galactic bulge. [3] NGC was discovered by the German-born British astronomer William Herschel on 24 May 1784. [6]
It contains several hundred thousand stars, and ranks among the densest globular clusters in the Milky Way. [9] It is at more than twice the distance of the Galactic Center in regions considered the Galactic halo. It hosts relatively many blue stragglers, stars that appear to be much younger than the cluster. It is thought these have lost part ...
This globular cluster is located at a distance of 114,000 light-years (35,000 pc) from the Sun and 96,000 light-years (29,000 pc) from the Galactic Center [4] and is one of the oldest known globular clusters in the Milky Way Galaxy, forming nearly 12 billion years ago.

The location of NGC 5466 (circled in red) NGC 5466 imaged with a 32-inch telescope NGC 5466 is a class XII globular cluster in the constellation Boötes.Located 51,800 light years from Earth and 52,800 light years from the Galactic Center, it was discovered by William Herschel on May 17, 1784, as H VI.9.
NGC 2808 is a globular cluster [6] in the constellation Carina. The cluster currently belongs to the Milky Way, although it was likely stolen from a dwarf galaxy that collided with the Milky Way. NGC 2808 is one of the Milky Way's most massive clusters, containing more than a million stars. It is estimated to be 12.5 billion years old.
The first known globular cluster, now called M 22, was discovered in 1665 by Abraham Ihle, a German amateur astronomer. [4] [5] [6] The cluster Omega Centauri, easily visible in the southern sky with the naked eye, was known to ancient astronomers like Ptolemy as a star, but was reclassified as a nebula by Edmond Halley in 1677, [7] then finally as a globular cluster in the early 19th century ...
