  • Mar Mezcua spends her days hunting invisible game. Lumbering giants, impossible to see with the naked eye, expertly camouflaged in the darkness of the night sky. She knows they're out there; she has seen their footprints, tracked their spoor. But for all the hours she has spent lying in wait for black holes, there is one breed she has never spotted. On paper, they are fairly unremarkable: average size, average mass. Black holes are not easy to study. They are so massive and compact that their gravity sucks in anything venturing too close. Even light cannot escape their gravitational clutches, so they reflect nothing, rendering them all but invisible. For the most part, the black holes found so far can be split into two camps. At the puny end are stellar mass black holes, formed by the explosive deaths of massive stars and typically weighing less than 100 times the mass of our sun
