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.

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 ...

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

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 ...

A groundbreaking study published in Communications Earth & Environment has called into question the long-standing assumptions about how our solar system came to be. Tiny shavings from a meteorite ...

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 ...

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

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA). In ...

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