A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...

Researchers analyzed 28 Ryugu asteroid samples and found preserved magnetic signals that record early solar system magnetic fields and water-driven alteration on its parent body.

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 ...

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 ...

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

The Solar System remains a unique natural laboratory for exploring the processes that govern planetary formation, evolution and dynamics. Contemporary research continues to refine our understanding of ...

Astronomers have revealed new research showing that millions of new solar system objects are likely to be detected by a brand-new facility, which is expected to come online later this year.

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

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 ...

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 ...
