A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

A group of astronomers has found a solar system 116 light-years from Earth that seems to challenge current theories about how ...

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

Astronomers have found a rocky planet where it should not exist, orbiting far from a cool red star. Could this strange “inside out” system rewrite how we think planets form?

New studies offer a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs. The findings reveal the distribution of ices in ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

Tiny grains from asteroid Ryugu are revealing clues to the magnetic forces that shaped the far reaches of the solar system over 4.6 billion years ago. The findings suggest the distal solar system ...

Most of our knowledge about the Solar System’s formation and evolution comes from the study of extraterrestrial rock samples called chondritic meteorites. These rocks, which are fragments of asteroids ...

Astronomers have witnessed the creation of a solar system for the first time. Data captured by the ALMA telescope in Chile and the James Webb Space Telescope showed planets forming around a star in ...

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...
