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.

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.

There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on ...

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 ...

Widespread magnetism dating from our solar system’s earliest beginnings some 4.57 billion years ago likely played a major role in creating orbital order out of chaos. But until now, magnetism’s role ...

A proposed five-satellite Cosmic Positioning System could measure cosmic distances directly and help address discrepancies in the Hubble constant through solar system–scale triangulation.
