The supermassive black gap on the coronary heart of our Milky Way galaxy has been photographed for the primary time, giving astronomers invaluable perception into how black holes work together with their environment.
The object, referred to as Sagittarius A*, was captured by the Event Horizon Telescope Collaboration, the identical world staff that took the well-known first-ever image of a black gap contained in the Messier 87 (M87) galaxy in 2019. Although the outlet itself is completely darkish, it’s encircled by a brilliant ring of glowing gasoline that’s been warped by its personal gravity.
While the staff acknowledged the visible similarities between the brand new image and 2019’s M87* picture, the plenty of the 2 black holes and the forms of galaxies surrounding them are very totally different. The researchers have been in a position to work out that Sagittarius A*, which sits on the middle of our small spiral galaxy, consumes gasoline at a a lot slower fee than M87*, which resides on the middle of an enormous elliptical galaxy and ejects a strong jet of plasma.
“If Sagittarius A* were the size of a doughnut, M87* would be the size of the Allianz Arena, the Munich football stadium just a few kilometers from where we are today,” Sara Issaoun, NASA Einstein fellow on the Harvard & Smithsonian Center for Astrophysics, advised a press convention on the European Southern Observatory in Germany. “This similarity reveals to us a key aspect of black holes no matter their size or the environment they live in. Once you arrive at the edge of a black hole, gravity takes over.”
