For some time now I’m fascinated by astronomy and reading and rereading magazines I’m discovering a magical and sensational world every day you discover something new and I decided by reading an article on Sagittarius A * which is my zodiac sign I have decided to share it with you!
It has been confirmed that in the center of the Milky Way a black hole of four million solar masses is actually hidden: the confirmation of the nature of Sagittarius A * comes from a series of observations made through the Gravity tool of ESO, the most powerful so far installed on the VLTI (the Very Large Telescope interferometer). Gravity combines the light coming from different telescopes to create a 130 meter diameter super telescope, which has been busy investigating the center of the Milky Way.
PIROETTE ON THE BORDER. The new observations show clusters of gas rotate in a circular orbit just outside the event horizon, the point of no return in which the matter around a black hole is irresistibly attracted towards it. The point closest to the black hole in which the external material can still push itself without ending up sucked is called a more internal stable orbit, and it is here that the gas has been observed to circle at a speed equal to 30% of that of light.The flashes of infrared radiation originating from this orbiting material and captured by the virtual telescope represent the most accurate observations of stable inner orbit gases of a supermassive black hole ever made. The study was published in the scientific journal Astronomy & Astrophysics.
THE PREVIOUS RESULTS. For the international collaboration of scientists working on the project, all this is equivalent to following the process of accretion of a black hole in real time. At the beginning of the year, the same group of astronomers had observed, with Gravity and Sinfoni, another instrument of the VLT, the sliding passage of a star – “S2”, which passes close to it every 16 years – in the gravitational field of Sagittarius A * (we had written here).
On that occasion it was possible to observe the effects of Einstein’s theory of relativity in an extreme galactic environment, as well as to detect three brilliant flashes of infrared emission, perhaps originated by the magnetic interactions in the gas orbiting the black hole. The observations made so far on this mysterious giant confirm the theoretical paradigms on the behavior of supermassive black holes.
I hope you enjoyed this new discovery guys greetings Saifer
