Galactic Giants: How black hole radiation might help life thrive

Amit Malewar

Radiation from black hole may paradoxically offer life a boost

Artist’s impression of a hypervelocity star ejected from the Large Magellanic Cloud. When a binary star system ventures too close to a supermassive black hole, the intense gravitational forces tear the pair apart. One star is captured into a tight orbit around the black hole, while the other is flung outward at extreme velocities—often exceeding millions of miles per hour—becoming a hypervelocity star. This illustration depicts this process: the original binary’s orbital path is shown as interwoven lines, with one star being captured by the black hole (near center) while the other is ejected into space (lower right).
