Some neighborhoods in the Milky Way may be better suited for making habitable planets than others.

Our galaxy's stars keep a record of its past. By reading those stories, astronomers are learning more about how the Milky Way came to be — and about the galaxy we live in today.

Reports that the James Webb Space Telescope killed the reigning cosmological model turn out to have been exaggerated. But astronomers still have much to learn from distant galaxies glimpsed by Webb.

Observations of faraway planets have forced a near-total rewrite of the story of how our solar system came to be.

Cora Dvorkin discovered new possibilities for what dark matter could be. Now she’s devising unorthodox ways to identify it.

Snow crystals come in two main types. The “pope” of snowflake physics has a new theory that explains why.

After an interstellar asteroid shot past the sun, scientists realized that there’s probably a lot of itinerant rocks out there.

Astronomers are puzzling over a paucity of planets in the galaxy measuring between 1.5 and two times Earth's size.

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.
