Sagittarius A * – Libra's largest supermassive black hole in the center of the galaxy – frees up radio jets that are pointed almost straight to the ground. Black holes do not emit any light that can be detected but certain to exhibit radio jets. This happens when large amounts of gases around black holes begin to swirl so quickly that it actually releases friction in the form of X-rays and radio waves – this is how scientists usually search for black holes.
In this case, researchers using the Atacama Large Millimeter / submillimeter Array (ALMA) telescope in Chile have noted that the radio beams from Sagittarius A * are aimed at us.
In a new paper led by the University of Nijmegen, PhD student Sara Issaoun was published in the Astrophysical Journal, the experts managed to look behind the large amount of gas covering the view from Earth to Sagittarius A * for the first time ever to make the discovery.
To make it survey the researchers exactly the scattered light that blocks the display of the black hole to produce an image of the region between space times surrounding properties.
The team found out that the black hole radio beam is pointing to a 300 million degree off Earth.
"This may indicate that the radio emission is produced in a disk of incident gas rather than a radio beam.
" However, it would make Sagittarius A * an exception to other radio transmitting black holes. The alternative could be that the radio beam almost points to us. "
There is no need to threaten, according to the team, since the jet will not cause any harm to Earth, but the research helps create an unprecedented image of the Black hole.
Future studies will also help experts improve understand black holes that remain largely mysterious and just as confusing.
