NGC 5139 Omega Centauri Globular Star Cluster
| Description |
Omega Centauri (ω Cen, Caldwell 80) is a globular cluster located in the constellation Centaurus. It was first identified as a non-stellar object by Edmond Halley in 1677. Situated approximately 17,090 light-years (5,240 parsecs) from Earth, Omega Centauri is the largest known globular cluster in the Milky Way, with a diameter of about 150 light-years. It is estimated to contain around 10 million stars and has a total mass of 4 million solar masses, making it the most massive globular cluster in our galaxy.
In contrast to most other galactic globular clusters, Omega Centauri is thought to have originated from the core remnant of a disrupted dwarf galaxy. |
