Our solar system is a weird place. Much more than a home to eight planets, it’s filled with a myriad of fascinating other smaller bodies, including moons, asteroids, and comets. In recent decades, ...

Samples from Ryugu, a small, near-Earth asteroid, preserve natural remanent magnetization (NRM) from the early history of the solar system. However, despite multiple studies, there is currently no ...

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 ...

Strange objects from other star systems are visiting our solar system. These interstellar visitors are scientifically valuable but disappear quickly. Scientists are calling for a global response ...

This reason is enough to delay the Artemis II mission further, says a Mexican nuclear physicist to the Starlust team.

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

Scientists have long believed that comets and a type of very primitive meteorite called carbonaceous chondrites were the sources of early Earth’s volatile elements — which include hydrogen, nitrogen, ...

Estimating ages of specific events is one of the most difficult problems in astrophysics. While we have a precise (and probably accurate) age for the solar system, we do not have precise ages for each ...

Oh, we humans do love a cleanly defined boundary, don’t we? They make things easier, after all. If we’re trying to categorize something, knowing what labeled bin to put it in is handy. If we’re ...

“While 3I/ATLAS is a visitor from interstellar space, travelling from outside the Solar System, its behaviour is completely ...
