Chinese scientists they discovered a mysterious barrier, which appears to prevent cosmic radiation from penetrating the center of the Milky Way. Even more strange, however, is that the area in question seems to be accelerating these rays.
The team used data collected by the Fermi Gamma-ray Space Telescope, a space observatory with the world’s largest gamma-ray detector.
While some rays were stopped by the aforementioned barrier, others first slowed and, after passing through, accelerated again. This has led researchers to believe that there is something like a particle accelerator at the center of our galaxy.
According to the server Phys.org perhaps the best explanation for this phenomenon would be the existence of a hypothetical supermassive black hole known as Sagittarius A *.
However, researchers have not been able to reach a definitive conclusion or rule out other possibilities (such as supernova remnants). In other words, this new research raises more questions than answers.
