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 ...

Astronomers might have found evidence of a structure located farbeyond Neptune, potentially giving us clues about the solar system’s primordial past. This discovery involves a dense concentration of ...

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 ...

The Japan Aerospace Exploration Agency's Hayabusa2 mission returned uncontaminated primitive asteroid samples to Earth. A comprehensive analysis of 16 particles from the asteroid Ryugu revealed many ...

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 ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

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 ...

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 team of scientists undertake a comprehensive analysis of samples returned from the Japan Aerospace Exploration Agency’s Hayabusa2 mission and provide invaluable insights into the formation and ...
