Meteorites are remnants of the building blocks that formed Earth and the other planets orbiting our Sun. Recent analysis of their isotopic makeup led by Carnegie’s Nicole Nie and published in Science ...

Moon impact 3.5 billion years ago reveals hidden Solar System history through tiny mineral grains. The discovery shows ...

A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision. The discovery suggests some early planets formed from ...

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 flyby probably happened several billion years ago, so how much would the orbital parameters change on such a timescale? Investigating the long-term evolution of the TNO population is ...

Might the first moments of planet formation be more understandable than ever before? Fresh observations suggest that the creation of worlds such as our own is perhaps happening right in front of us, ...

Studying asteroids addresses a number of unknowns in planetary science. Investigating them makes use of asteroidal meteorites, remote observations and space-based missions. However, to fully ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...

There’s a bit of a paradox about our galaxy: it’s both jam-packed with stars and cavernously empty. The Milky Way is crowded in the sense that it holds hundreds of billions of stars, as well as ...
