In my January 23, 2026, “The Universe” column, I wrote about some of the biggest bangs the universe has to offer: exploding stars, hiccupping magnetars, stellar disruptions and colliding black holes.

"We are not just replacing the black hole with a dark object; we are proposing that the supermassive central object and the ...

Researchers believe they have found the signal of a pulsar, the ancient core of a rapidly spinning star, at the center of the Milky Way, near a supermassive black hole. This discov ...

Deep inside a nearby galaxy cloaked in thick clouds of gas and dust, astronomers have uncovered a surprising treasure trove ...

Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, ...

Sagittarius A* may be a dense dark matter core instead of a black hole, offering a new explanation for the Milky Way’s central gravity.

Previous observations of stars whipping around an unseen mass—especially a bright star called S2—have pointed to an object ...

Researchers looking for signs of extraterrestrial life instead stumbled upon a pulsar at the center of the Milky Way galaxy.

Supermassive black holes appear early in the universe, too big to match growth models. New simulations suggest even "light seed” black holes could bulk up rapidly through frenzied feeding bursts ...

Hubble catches a spiral galaxy mid-flight, shedding glowing gas as it battles the harsh environment of a nearby galaxy ...
