The orbiting spot could be a bubble of hot gas whipping around Sagittarius A* at around 30% of the speed of light.
, released in 2019, which depicted the supermassive black hole at the heart of the galaxy Messier 87 . Earlier this year, the same collaboration unveiled the first image of Sgr A*.
The discovery comes because ALMA collected some of its data after a burst, or flare, of X-rays from the heart of the Milky Way detected by NASA's. Scientists have previously linked flares like this to magnetic interactions in hot gas bubbles that orbit close to Sgr A* at rapid speeds. The team suggests that the hot spots detected at infrared wavelengths could be the result of gas bubbles that become visible at longer wavelengths of light when they cool down.
Using ALMA, astronomers and astrophysicists can study polarized radio wave emissions from Sgr A*, which they can use to investigate the magnetic field surrounding the supermassive black hole. The new research could help in this investigation by better constraining the shape of this magnetic field and details of the surroundings of Sgr A*, the scientists hope.

“Mind-Blowing” Hot Gas Bubble Detected Zipping Around the Milky Way’s Supermassive Black HoleAstronomers have spotted signs of a ‘hot spot’ orbiting Sagittarius A*, the black hole at the center of our galaxy, using the Atacama Large Millimeter/submillimeter Array (ALMA). The finding helps us better understand the enigmatic and dynamic environment of our supermassive black hole. “We think
