We have been decades trying to decode our supermassive black hole, but important clues might have been in the front
Using a range of 13 radio telescopes, astronomers from the Max Planck Institute were able to enter Sagittarius A * (pronounced as A-star), the region where the supermassive black hole of the Milky Way is located. And after clearing the noise of the diffused light that surrounds him, they discovered that the powerful radio broadcast that exploded from the black hole came from only a small area that could be directed directly to the Earth. The study was published Monday on The Astrophysical Journal and, if confirmed, could shed new light on Sgr A * and its radio jets
Black Hole Blasts
Supermassive black holes are quite common in our universe sits in the hearts of most large galaxies. Their strong gravitational fields allow them to suck and destroy objects that are too close to them. And while they swallow most of this heavenly matter, a small part avoids the black hole and explodes back into space. These emissions, known as jets, carry plenty of radio waves and travel at almost the speed of light. In a phenomenon known as light scattering, the particles of starlight that lie between Earth and Sgr A * are scattered in the sky, making it difficult to distinguish that star from the black hole radio broadcasts. But recently, a team of researchers managed to isolate radio broadcasting using very long interferometry – a technique that combines multiple telescopes to create massive, extremely powerful. Using 13 ranges from all over the world, they blocked the diffused light and were studying the emissions themselves.
They found that it came from a symmetrical source that coincided with the "jet" theory, as they were sprayed from black holes in opposite directions. They also found that emissions were much narrower than they thought. So narrow, in fact, that they only come to us at a 300 millionth degree – suggesting that it is directed almost directly to Earth.
With the luck of drawing, it means we can have a direct look at one of the defining characteristics of our black hole. And do not worry that the airplane actually blows us up because, as far as we know, to be in its visibility, it does not put us in danger. If nothing else, it would allow us to study the flow in impeccable detail and shed light on the mysterious nature of Sgr A *.
