Deep within the Kuiper belt, some small worlds look like they were assembled from two mismatched snowballs pressed together.

Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.

Far beyond Neptune, in the frozen depths of the Kuiper Belt, many ancient objects oddly resemble giant snowmen made of ice and rock. For years, scientists wondered how these delicate two-lobed shapes ...

In the distant reaches of the solar system are many icy objects that resemble snowmen. Now, a new study reveals the simple ...

Astronomers have long thought solar systems follow a simple pattern similar to our own: small, rocky worlds orbit close to the Sun, while large gaseous planets sit further out. For decades, ...

Active small bodies—including comets, active asteroids, icy minor planets, and transitional objects—occupy a unique position in planetary science. As ...

Jupiter’s icy moons may have been seeded with the chemical ingredients for life from the very beginning. An international ...

Chalk up another victory for “Conan the Bacterium”—a rugged germ that fresh research suggests could conquer the solar system.

A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form. Reading time 3 minutes Astronomers have discovered a star system that’s out of ...

New research using the James Webb Space Telescope offers the most detailed portrait yet of how auroras form on Uranus.
