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 ...

"The Solar Family" is an 11-minute educational film produced by Encyclopedia Britannica Films in 1936. It presents the evolution of the solar system through the lens of the planetesimal hypothesis, a ...

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 ...

A rocky planet beyond gas dwarfs in LHS 1903 indicates that planetary systems form in unexpected ways.

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA). In ...

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 years ago. The star is surrounded by a ...

What can a newly discovered interstellar comet teach scientists about solar system formation and evolution? This is what a recent study presented at the National Astronomy Meeting 2025 hopes to ...

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 ...
