Astronomers Discover Triple-Star System with Black Hole

The unexpected finding challenges existing theories on black hole formation and suggests new avenues for research.

Scientists have identified a black hole in the V404 Cygni system, accompanied by two stars, 8,000 light-years from Earth.
This is the first time a black hole has been observed with two companion stars, one of which is in a distant orbit taking 70,000 years to complete.
The discovery was accidental, made while reviewing archival data from various observatories, including the Gaia satellite.
The existence of the distant star challenges the prevailing theory that black holes form through supernovae, which typically expel nearby stars.
Researchers propose that this black hole may have formed through a 'direct collapse,' a process without a supernova explosion, suggesting a need to explore similar systems.
