A central massive object (CMO) is a high mass object or cluster of objects at the centre of a large star system, such as a galaxy or globular cluster. In the case of the former, the CMO may be a supermassive black hole , a nuclear star cluster , or even both together.
Corundum is a crystalline form of aluminium oxide (Al 2 O 3) typically containing traces of iron, titanium, vanadium, and chromium. [3] [4] It is a rock-forming mineral.It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. [7]
Scientists at the Max Planck Institute for Extraterrestrial Physics in Germany using Chilean telescopes have confirmed the existence of a supermassive black hole at the Galactic Center, on the order of 4.3 million solar masses. [5] Later studies have estimated a mass of 3.7 million [34] [35] or 4.1 million solar masses. [24]

Deep underneath the flat plains of the Australian outback, a massive object lies buried. The hulking structure, which has “magnetic anomalies,” is likely a colossal asteroid crater, ...
This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most massive objects, volume, density, and surface gravity, if these values are available.
Researchers estimate that it could contain somewhere between 1,000 and 10,000 trillion stars.
