Astronomers have made a surprising discovery that challenges current theories of galaxy formation. A colossal disk-shaped galaxy, nicknamed the "Big Wheel," has been found just two billion years after ...

Sgr A* at the heart of the Milky Way has a mass 4.3 million times that of the sun, while the supermassive black hole in the galaxy Messier 87 (M87) has a mass around 5 billion times that of our star! ...

It's about 6.5 billion times as massive as our Sun — that's enormous even compared to other supermassive black holes and lives in the center of the Messier 87 galaxy. And as far as experts can ...

Sgr A*, in turn, is dwarfed by some supermassive black holes detected in other large galaxies such as one with a mass 6.5 billion times greater than that of the sun in a galaxy called Messier 87.

Metsähovi Radio Telescope, located in the forests outside Greater Helsinki in Finland, is one of the telescopes used to take the first image of the M87 black hole together with its powerful jet.

The latest achievement was the team’s second since April 2019, when it released the first image of a black hole from the Messier 87 galaxy, which is about 55 million light years from Earth.
