Researchers have confirmed that a possible microlensing event witnessed in 2011 was due to the presence of a free-floating Black Hole roaming through interstellar space—the first of its kind ever observed. The group has published a paper describing their findings on the arXiv preprint server.
Scientists have assumed for some time that many Black Hole are wandering around in interstellar space, but until now, they have not found one. This is due to the very nature of a. They are difficult to spot against the black backdrop of space. The evidence for their existence was strong.Prior research has shown that are often formed when stars reach the end of their lives and their cores collapse, generally producing a supernova. And because many such supernovae has been observed, it seemed clear that many must have been created as a result.
They found the position of the star appeared to change. The researchers suggest the change could only be due to an unseen moving object exerting a force that was pulling on the light as it passed by an interstellar Black Hole.The researchers continued to study the star and its light, and eventually ruled out the possibility of any light coming from the lensing and also confirmed that the magnification had a long duration, both of which are prerequisites to confirming the existence of a. The evidence confirms the sighting of a free-floating. The researchers were even able to measure its size, at seven solar masses. They also found that it is traveling at approximately 45 km/second.
