Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

LIVERMORE, Calif. — Scientists have found that calcium, aluminum-rich inclusions (CAIs), some of the oldest objects in the solar system, formed far away from our sun and then later fell back into the ...

New research suggests that Jupiter’s icy moons may have formed with complex organic molecules already embedded in their building blocks.

Tiny grains from asteroid Ryugu are revealing clues to the magnetic forces that shaped the far reaches of the solar system over 4.6 billion years ago. The findings suggest the distal solar system ...

Paleomagnetic analysis of 28 Ryugu asteroid particles reveals stable magnetization acquired within millions of years of solar ...

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 ...

MIT scientists analyzed one of several particles (shown in black) from the asteroid Ryugu, and found evidence that a weak magnetic field likely existed in the outer solar system where the asteroid is ...
