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

A central pillar of cosmology — the universe is the same everywhere and in all directions — is surviving a storm of possible evidence against it.

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 the ultra-powerful James Webb Space Telescope launches later this year, Laura Kreidberg will lead two efforts to check the weather on rocky planets orbiting other stars.

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

Jupiter and Saturn should be freezing cold. Instead, they’re hot. Researchers now know why.

Groundbreaking results show that neutron stars of different masses may have the same size — upending astrophysical models.

A new proposal would use quantum hard drives to combine the light of multiple telescopes, letting astronomers create incredibly high-resolution optical images.

Radio waves, longer and less energetic than visible light, give astronomers access to some of the most obscure physics in the cosmos.
