International astronomers have for the first time witnessed the birth of a planetary system beyond Earth's sun that could one ...

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 ...

Two massive planets may have once existed in early solar system before being ejected, leaving behind evidence in unusual ...

A new study published in The Astrophysical Journal has traced six chemically distinct families of the Solar System's oldest meteorites to a single ring-shaped dust trap just beyond Jupiter's orbit — ...

An image from the ALMA telescope array in Chile shows jets of silicon monoxide blowing away from the young star HOPS-315. The blue jet is moving towards Earth, and the red jet is moving away from us.

Isotope ratios found in meteorites suggest that a supernova exploded nearby while the sun and solar system were still forming. But the blast wave from a supernova that close could have potentially ...

With simulations that go into finer details than ever before, Brooke Polak of the University of Heidelberg and Hubert Klahr at the Max Planck Institute for Astronomy (MPIA) have modeled a key phase in ...
