NGC 1300 is a barred spiral galaxy located about 65 million light-years away in the constellation Eridanus. The galaxy is about 110,000 light-years across. It is a member of the Eridanus Cluster, a cluster of 200 galaxies, [3] [4] [5] in a subgroup of 2-4 galaxies in the cluster known as the NGC 1300 Group. [6] [7] [8] It was discovered by John Herschel in 1835. [9]
In the core of the larger spiral structure of NGC 1300, the nucleus shows a "grand-design" spiral structure that is about 3,300 light-years long. Only galaxies with large-scale bars appear to have these grand-design inner disks — a spiral within a spiral. Models suggest that the gas in a bar can be funneled inwards, and then spiral into the center through the grand-design disk, where it can potentially fuel a central supermassive black hole (SMBH). NGC 1300 is not known to have an active nucleus, indicating that its central black hole is not accreting matter. The SMBH has a mass of 7.3+6.9
−3.5×107 M☉ . [10] [11]
One supernova has been observed in NGC 1300: SN 2022acko (type IIP, mag. 15.8). [12] [13]
