Tiny shavings from a single meteorite could completely overturn our understanding of how the solar system formed, after the space rock turned out to be older than expected. Previous research suggests ...

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 ...

The standard story of the origin of our solar system has gone like this: 4.6 billion years ago, a giant cloud of dust hung frozen in space. Then the explosion of a nearby star caused part of that dust ...

In this study, NRM measurements suggest that the observed characteristics of Ryugu particles is a chemical remanent magnetization, likely acquired during growth of framboidal magnetite that occurred ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...
