NGC 253 – Galaxy in Sculptor (30th Aug 2024)

NGC 253 is the brightest member of the Sculptor Group of galaxies.

NGC 253 is the brightest member of the Sculptor Group of galaxies, which includes luminaries such as NGC 247, NGC 300, and NGC 55. The galaxy was discovered by Caroline Herschel in 1783 during one of her systematic comet searches.

Located 11.4 million light years away, it is classified as a starburst galaxy, which means that it is currently undergoing a period of intense star formation. The central 10,000 light years of this galaxy shows evidence of a violent burst of star formation that began some 30 million ago.

Research suggests the presence of a supermassive black hole in the centre of this galaxy with a mass estimated to be 5 million times that of the Sun, which is slightly heavier than Sagittarius A*, our Milky Way’s central black hole.
