Short-lived radioisotopes such as aluminum-26 influenced early solar system heat, water retention and the formation of Earth-like rocky planets, according to meteorite analyses and models.

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 ...

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 ...

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 ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

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 ...

Rocky fireballs like the one that fell over Alberta, Canada last year shouldn't originate from the icy Oort Cloud... but this one apparently did. When you purchase through links on our site, we may ...

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 ...
