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 ...

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 ...

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 ...

Scientists were able to see the moment when planets began to form around a star. Astronomers have witnessed the birth of a solar system beyond our own for the first time. An international team of ...

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 ...

Interstellar comet 3I/ATLAS makes its closest Earth approach on Dec. 19, offering astronomers a rare chance to study a visitor from beyond the solar system ...

In a groundbreaking discovery, astronomers have, for the first time, observed the formation of a new solar system. Using a combination of data from the Atacama Large Millimeter/submillimeter Array ...

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 ...

Super-Earths and sub-Neptunes, planets with sizes between Earth and Neptune, constitute approximately one-third of known exoplanets but are absent in our solar system. Their prevalence elsewhere and ...

A team combined compositional data of primitive bodies like Kuiper Belt objects, asteroids and comets with new solar data sets to develop a revised solar composition that potentially reconciles ...
