NGC253, THE SCULPTOR GALAXY on 2023-09-08,9
NGC253, The Sculptor Galaxy (also known as the Silver Dollar Galaxy and Caldwell 65) is an intermediate spiral galaxy in the constellation Sculptor. The Sculptor Galaxy is a starburst galaxy, which means that it is currently undergoing a period of intense star formation. NGC253's starburst has created several super star clusters near NGC253's center (discovered with the aid of the Hubble Space Telescope): One such star cluster has a mass of 1.5 million solar masses. An even more massive star cluster, heavily obscured by NGC253's interstellar dust, has a mass of about 14 million solar masses. The super star clusters are arranged in an ellipse around the center of NGC253, which from the Earth's perspective appears as a flat line. Star formation is also high in the northeast of NGC253's disk, where many red supergiant stars can be found. Other peculiarities found in NGC253 suggest that a gas-rich dwarf galaxy collided with it 200 million years ago, disturbing its disk and starting the present starburst. Research suggests the presence of a supermassive black hole in the center of the galaxy with a mass estimated to be about 5 million times that of our Sun. The Sculptor Galaxy is located about 10.89 million light-years from our Earth.
