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

"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 ...

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 ...

Planets may have begun forming in our solar system when the sun was still young — millions of years earlier than previously thought, a new study of long-dead stars suggests. In the study, published ...

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 — ...

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 ...

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 ...

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.

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 ...
