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 ...

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, ...

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

Researchers have been focusing on the study of our solar system for centuries, looking at the physics, dynamics, as well as the composition of solar system bodies. Our solar system – which includes ...

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

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

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 ...

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, ...

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 : ...

There’s a bit of a paradox about our galaxy: it’s both jam-packed with stars and cavernously empty. The Milky Way is crowded in the sense that it holds hundreds of billions of stars, as well as ...
