by An international team of researchers has 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.
Prior research has shown that black holes are often formed when stars reach the end of their lives and their cores collapse, generally producing a supernova.
And because many such supernova have been observed, it seemed clear that many black holes must have been created as a result.
