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, ...

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

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 ...

Introduction: NASA's solar system exploration paradigm : the first fifty years and a look at the next fifty / James L. Green and Kristen J. Erickson -- Part I. Overview. Exploring the Solar System : ...

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 ...

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, ...

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread ...

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 ...
