The latest AI algorithms are probing the evolution of galaxies, calculating quantum wave functions, discovering new chemical compounds and more. Is there anything that scientists do that can’t be automated?

Astronomers claim in a new paper that star motions should make it easy for civilizations to spread across the galaxy, but still we might find ourselves alone.

Brief cosmic blips called fast radio bursts have puzzled astronomers since their discovery earlier this decade. Now researchers appear to be close to understanding what powers them.

Priyamvada Natarajan has pioneered the mapping and modeling of the universe’s invisible contents, especially dark matter and supermassive black holes.

Subatomic particles called muons are thought to have streamed through the atmosphere and irradiated megafauna like the monster shark megalodon.

Astronomers couldn’t find enough satellite galaxies orbiting the Milky Way. Now they have the opposite problem.

Two independent papers vanquish lingering doubts about LIGO’s historic discovery of gravitational waves.
