Known as Sgr A* – pronounced “Sagittarius A star” – the supermassive black hole is four million times the mass of the sun and is known to exhibit flares that can be observed in multiple wavelengths, ...

In the past, astronomers have estimated Sgr A*’s rotation speed but reported that the supermassive black hole either wasn’t spinning at all or that it was spinning at almost the maximum rate ...

The image reveals the swirling magnetic fields around Sagittarius A* (Sgr A* ... are the bedrock of all of this. Anything which gives us more insight into how black holes and magnetic fields ...

Scientists have been actively observing Sagittarius A* (Sgr A*)— a supermassive black hole roughly 4 million times the mass ... “Sgr A*’s flare evolves and changes quickly, in a matter of hours, and ...

inflowing gas can sometimes find its way into the supermassive black hole at the very center. When Sgr A* feeds on this material, it emits X-ray flares that propagate outwards in all directions.
