The return of these extraterrestrial samples to Earth in 2020 opened the door to new hypotheses. These grains taken from Ryugu, an asteroid located beyond Jupiter, contain crucial elements for the ...

What can dust grains that were returned to Earth from the asteroid Ryugu teach scientists about the early solar system? This is what a recent study published in AGU Advances hopes to address as an ...

Thanks to asteroid Ryugu, now we know. The asteroid is a peculiar one – maybe even an extinct comet. It was visited by the Japanese mission Hayabusa-2, which collected samples from the surface ...

Ryugu samples reveal phosphorus-rich grains crucial for early Earth Phosphorus-rich grains may explain early life chemistry on Earth Ryugu asteroid's grains offer insight into Solar System’s formation ...

New isotopic analysis of asteroid Ryugu’s samples from Japan’s Hayabusa2 mission indicates a formation near Jupiter, not beyond Saturn, revealing intricate details about the early Solar System’s ...

Credit: Kochi/JAXA New research based on samples from asteroid Ryugu reveals that phosphorus-rich compounds could explain how Earth became habitable. These findings emphasize the importance of ...

A team led by researchers at MIT examined the particles from Ryugu to see if they showed signs of an ancient magnetic field. If such a field existed, it would have been weak, around 15 microtesla ...
