The historic image of Sagittarius A* is the culmination of a decades-long astronomical quest—and a crucial step toward a new understanding of black holes, gravity and spacetime

Revisiting a controversial claim, astronomers are laying bare deep uncertainties about our understanding of galactic centers

A recently spotted bright light in the sky is improving astronomers’ understanding of stellar death

The $25-million facility in Namibia will be the continent’s first millimeter-range astronomical observatory

Weighing in at seven times the mass of our sun, the dark object is by far the best-yet candidate for a free-floating stellar-mass black hole

Subtle signals from black hole mergers might confirm the existence of “Hawking radiation”—and gravitational-wave detectors may have already seen them

Recent work has shown how “naked singularities” might defy the cosmic censorship conjecture

In trying to explain the spectacular star trails of the star cluster Palomar 5, astronomers stumbled on a very large trove of black holes.

New research shows that there are problems even quantum computers might never be able to solve
