The dense, dormant object is hiding in plain sight.
thanks to the warm glow of matter that allows you to see where the black hole lurks.n’t accreting matter, superheating it,ble except for its gravitational effects on the star.“Our Gemini follow-up observations confirmed beyond reasonable doubt that the binary contains a normal star and at least one dormant black hole,” El-Badry said. “We could find no plausible astrophysical scenario that can explain the observed orbit of the system that doesn’t involve at least one black hole.
But current models of binary systems involving a black hole and a star don’t explain Gaia BH1’s system. According to, the star that gave way to the black hole in the system would be massive, and it should have engulfed the other star in the system before the black hole formed.will in time help astrophysicists refine their models of how these systems take shape and evolve.
