Black holes grow in two ways. They accrete matter over time, and they merge. Astrophysicists believe that it takes a galaxy ...

The study, published in the journal Nature Astronomy, is based on recent observations from the Event Horizon Telescope (EHT), which captured the first direct image of Sgr A* in 2022. The EHT, a ...

Supermassive black holes, with masses more than a million times that of our sun, are among the most fascinating and ...

Researchers have discovered compelling evidence suggesting that the supermassive black hole at the center of our Milky Way galaxy, known as Sagittarius A* (Sgr A*), is likely the result of a past ...

According to the researchers, Sagittarius A* is like a powerful engine that sucks matter now and then and spits it out at ...

For Sgr A*, we'd only have to wait one night. In one evening, you'd see many orbits of matter and light around the black hole. But for that to work, the EHT would need a lot more telescopes.

6 in the journal Nature Astronomy, builds on recent observations from the Event Horizon Telescope (EHT), which captured the first direct image of Sgr A* in 2022. The EHT, the result of a global ...

The Event Horizon Telescope (EHT) Collaboration has conducted test ... images of supermassive black holes at the hearts of M87 and Sgr A at the lower frequency of 230 GHz, these new results ...
