How to Weigh a Black Hole Using NASA's Webb Space Telescope
Release date: October 17, 2018
Webb will examine the center of active galaxy NGC 4151
Galaxies and their central, supermassive black holes are inextricably linked. Both grow in lockstep for reasons that aren't yet understood. To gain new insights, Webb will turn its infrared gaze to the center of a nearby galaxy called NGC 4151, whose supermassive black hole is actively feeding and glowing brightly. By measuring the motions of stars clustered around the black hole and comparing them to computer models, astronomers can determine the black hole's mass. This challenging measurement will test the capabilities of Webb's innovative instrument called an integral field unit.
