You might think we know the solar system pretty well, but there's a lot more to our cosmic neighborhood than initially meets the eye (or telescope). Most of the good stuff, such as the planets, moons ...

A newly discovered object orbiting far beyond Neptune has its closest approach to the Sun pointed in the opposite direction from every other known body like it, weakening one of the central ...

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 ...

Astronomers are closing in on one of the most tantalizing possibilities in planetary science, evidence that a previously unknown world may be lurking in the outer reaches of the solar system. The ...

(Nanowerk News) Observations of the outer Solar System with the Subaru Telescope have discovered new bodies where none were expected. The new objects are likely members of a much larger population ...

Tiny shavings from a single meteorite could completely overturn our understanding of how the solar system formed, after the space rock turned out to be older than expected. Previous research suggests ...
