NGC 5128 Centaurus A Galaxy

Centaurus A, also known as Caldwell 77 or NGC 5128, is a galaxy located in the constellation Centaurus. It was discovered in 1826 by Scottish astronomer James Dunlop from his home in Parramatta, New South Wales, Australia. There is ongoing debate in the scientific community regarding the galaxy’s fundamental properties, including its Hubble type—whether it is a lenticular galaxy or a giant elliptical galaxy—and its distance from Earth, which is estimated to be between 11 and 13 million light-years.

Centaurus A is the closest radio galaxy to Earth, as well as the nearest BL Lac object, making its active galactic nucleus a subject of extensive study among professional astronomers. It is also the fifth-brightest galaxy in the sky, making it an ideal target for amateur astronomers. However, it is only visible from the southern hemisphere and low northern latitudes.
