In 2019, the Event Horizon Telescope released a historic image of a supermassive black hole in another galaxy. The follow-up — an image of Sagittarius A* — shows it shimmering at the center of our own.

Researchers say we’re on the cusp of “GoPro physics,” where a camera can point at an event and an algorithm can identify the underlying physics equation.

Dwarf galaxies weren’t supposed to have big black holes. Their surprise discovery has revealed clues about how the universe’s biggest black holes could have formed.

When astronomers tried to confirm a signal from the birth of the first stars after the Big Bang, they saw nothing.

In computer simulations of possible universes, researchers have discovered that a neural network can infer the amount of matter in a whole universe by studying just one of its galaxies.

Puzzling particles, quirky (and controversial) quantum computers, and one of the most ambitious science experiments in history marked the year’s milestones.

The James Webb Space Telescope has the potential to rewrite the history of the cosmos and reshape humanity’s position within it. But first, a lot of things have to work just right.

After a search of neutron stars finds preliminary evidence for hypothetical dark matter particles called axions, astrophysicists are devising new ways to spot them.

Brown dwarfs such as “The Accident” are illuminating the murky borderlands that separate planets from stars.
