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 ...

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 ...

Moon impact 3.5 billion years ago reveals hidden Solar System history through tiny mineral grains. The discovery shows asteroid bombardment continued long after the Late Heavy Bombardment period.

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, ...

The asteroid belt is found orbiting between Mars and Jupiter and is a vast collection of rocks that is thought to be a planet that never formed. When our solar system formed 4.6 billion years ago, the ...

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 ...

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 ...

Juice observed 3I/ATLAS during perihelion, when Earth-based telescopes could not. Spectroscopic observations measured water ...
