A team of scientists used light from carbon ions in a distant galaxy to determine the rotation speed of gas around the central object. A sharp acceleration of the gas toward the center pointed to a black hole with a mass of about 6.3 billion Suns. This is the first dynamical weighing of a black hole

The Webb telescope spotted a multitude of tiny red galaxies in the early Universe. They were confused with dazzlingly bright galaxies where a black hole heats dust like a blast furnace. Though their color 'portraits' are similar, the red dots have cooler dust—meaning their 'engines' run more modestl

The quasar SDSS J2318, pretending to be a quiet one with weak emission lines, concealed inside a furious wind accelerated to 0.3 the speed of light. This outflow is capable of sweeping the interstellar medium out of its host galaxy, forever halting star birth. The discovery, made through spectroscop
