Milky Way’s Center Comes Into View: First Photo of Sagittarius A*

The Event Horizon Telescope released the first image of the Milky Way’s central black hole, Sagittarius A*, in 2022. The 4-million-solar-mass object lies about 27,000 light-years away. Eight linked radio observatories formed an Earth-sized telescope, and the ring around the shadow matches General Relativity despite the object’s minute-scale variability; researchers now plan time-resolved movies to study gravity in action.
