A supermassive black hole

First-ever model simulations of individual stars in a star cluster in the process of formation suggest possible mechanisms for the formation of intermediate-mass black holes
In a distant galaxy, the supermassive black hole's intermittent gas fluxes led to the discovery of a smaller black hole in its orbit
Researchers have discovered that the star cluster IRS13 near the supermassive black hole SagittariusA* at the center of our galaxy is much younger than predicted
