CNN) – Scientists have found evidence that the “sleeping monster” at the center of the galaxy containing the Earth Milky Way has suddenly woken up many times, devouring many stars without anyone knowing.
The black hole Sagittarius A* (Sgr A*) is a supermassive black hole, also known as a “monster black hole” by astronomers, 4 million times as massive as the Sun and believed to have been sleeping for many years. But there is growing evidence of mysteriously missing stars and gas clouds nearby.
New research published in the Astrophysical Journal, from NASA’s Space Telescope Science Institute, has captured the mysterious beams of death radiation that this monster black hole occasionally emits, radiating out in an hourglass shape. above and below the plane of the galaxy containing the Earth.
According to SciTech Daily, these terrifying plasma beams heat the gas beyond the galactic plane, forming Gamma rays and X-rays that Earther telescopes have captured.
Among the evidence, the most prominent is the Hubble Space Telescope (NASA/ESA) image of a bright gas node impacted by an invisible jet jet from a black hole.
According to the authors, when the galaxy containing the Earth was still young, this central black hole was as bright as a quasar (looks like a star in the sky, but is not actually a star) because of the radiation which it emits when it devours matter.
Currently, the black hole sleeps most of the time, but still wakes up regularly to eat snacks if any unlucky object loiters near it. According to astronomer Geral Cecil from the University of North Carolina, a member of the research team, the aforementioned evidence is also compared with an active black hole in the galaxy NGC 1068, 47 million light-years from Earth. shining.
At its most recent intense “eating”, a new estimate 2-4 million years ago, our monstrous black hole produced enough energy for 2 giant gamma-ray bubbles detected by the Telescope. NASA’s Fermi gamma-ray space in 2010, surrounded by two X-ray bubbles discovered by the ROSAT satellite in 2003.
