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 ...

The discovery provides new insights into the question, 'how large can a planet be?' An illustration of the HR 8799 system with three of its gas ...

Ever since scientists started looking at meteorites with microscopes, they’ve been puzzled–and fascinated–by what’s inside. Most meteorites are made of tiny beads of glass that date back to the ...

New studies offer a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs. The findings reveal the distribution of ices in ...

About 4.6 billion years ago, our corner of space was basically just a boring cloud of gas and dust floating around, and then something amazing happened that turned this mess into the planets, moons, ...

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 ...

Discovery of oxygen raises new questions about how solar system formed. In this undated photo, Rosetta finds oxygen on comet 67P. ESA/Rosetta/NavCam – CC BY-SA IGO 3.0 — -- The European Space ...

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 ...
