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

Researchers from the Nevada Center for Astrophysics at UNLV (NCfA) have found strong evidence in a study published in Nature ...

The EHT Collaboration released images of M87*, the supermassive black hole at the centre of the M87 galaxy, in 2019, and of Sgr A*, the black hole at the heart of our Milky Way galaxy, in 2022.

EHT researchers are already analyzing data from Sgr A* and M87 at the new frequencies that could be released within the next year. In addition, new observatories may be added to the telescope to ...

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.

Supermassive black holes, celestial objects with masses greater than a million times that of the Sun, remain one of the ...

EHT, D. Pesce, A. Chael "With the EHT ... These black holes—M87* and Sgr A*—are supermassive black holes found at the center of galaxies. These black holes are incredibly dense regions ...
