New work from Carnegie’s Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is ...

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 ...

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 ...

Here’s what you’ll learn when you read this story: Observations of the young HOPS-315 star system show an environment analogous to what our own nascent Solar System would have looked like billions of ...

The discovery of a planet that is far too massive for its sun is calling into question what was previously understood about the formation of planets and their solar systems. The discovery of a planet ...

The Sun's formation caused temperature differences in the surrounding disk of gas and dust. Inner, hotter regions formed rocky planets from less volatile elements. Outer, colder regions allowed ...

A new explanation for the solar system's radioactive elements suggests Earth-like planets might be found orbiting up to 50 per cent of sun-like stars ...
