Astronomers have discovered the first "black hole triple" system, consisting of a black hole hungrily feeding on a companion star while being orbited by a more distant, cautious star.
Black holes form during the violent death of massive stars in supernova explosions, but this surprising discovery could indicate a more gentle black hole birthing process called "direct collapse." That is because if the origin of this black hole had been more violent, it would have supplied a "pre-natal kick" that would have launched the loosely bound distant star out of this triple star system.
