new photo of the supermassive black hole at the center of our galaxy. Sagittarius A* was captured in this image by the Event Horizon Telescope. Polarized light shows the black hole and the magnetic field surrounding it.
The first such photo of the black hole at the heart of the Milky Way,
For the first time, scientists were able to measure the polarization, or magnetic field signature, in such a close vicinity of the shore of Sagittarius A*. There are also many indications that such fields exist around all black holes.
Black holes are objects so massive that they absorb even light that comes into their vicinity. This is a region of space-time that nothing can leave. However, scientists have discovered that black holes not only absorb matter, but also sometimes release it. In a similar way to Sagittarius A*, a few years ago the light around the M87 black hole was examined, which revealed that the magnetic field surrounding it allows it to “spit” material back into the surrounding environment.
New photos of Sagittarius A* reveal that this mechanism may also be at work in its case. The polarization of both black holes is similar, and research has revealed that a strong and ordered magnetic field is crucial in understanding how gases and matter interact with these objects.
Black holes are not easy to capture in photos. We only managed to do this in two cases
Sagittarius A* was discovered by scientists back in 1974. Years of observations have identified the object in the center of the Milky Way as a black hole that swallows everything in its reach.
Although black holes have been known to astronomers for decades, Sagittarus A* is only the second such object that has been converted (in fact, these are dozens of images superimposed on each other and processed in post-production) into a photograph. The first image was also produced by the Event Horizon Telescope team. It was the black hole of the M87 galaxy, 55 million light-years away from Earth.
