Nearest active black hole, 12 million light years away from Earth, the size of 16 moons

Space is an ocean of wonders where many amazing things reside. In this ‘black hole’ has its own importance, about which many mysteries still remain intact. Astronomers at Curtin University as part of an international team have captured the “largest” yet ever-so-largest yet ever-so-ever yet active black hole ever seen near Earth, scientists said. This research is published in the journal Nature Astronomy. The discovery was released publicly on Thursday, thanks to which scientists have taken a deep dive into the black hole at the center of the galaxy ‘Centaurus A’, about 12 million light-years away.

News agency Xinhua gave this information in its report. Despite the galaxy’s considerable distance from Earth, this black hole appears to be spread out to the extent of 16 full moons. Although it is not possible to see it with the naked eye. The images were captured using the Murchison Widefield Array (MWA) telescope in Western Australia. This telescope is capable of detecting and photographing the emitted radio waves.

55 million times more mass than the Sun
Study lead author Benjamin McKinley said these radio waves come from the ‘supermassive black’ hole in the center of the galaxy. When a black hole 55 million times the mass of the Sun explodes, gas and material are released from it at the speed of light. This causes the ‘radio bubble’ to expand outwards. McKinley said it forms a disk around the black hole. As material gets closer to the black hole, powerful jets form on either side of the disk, ejecting most of the material back into space.

McKinley said this is why the center of the photos appears brighter. Earlier this month, in a new research published in the Astrophysical Journal Letters, scientists proposed that black holes could become more massive as the universe expanded. Black holes absorb the light coming towards them, so they cannot be seen with the naked eye. Some black holes can be 50 to 100 times larger than the Sun.
