"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 ...

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 ...

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 ...

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.

Leonardo Testi and team investigate the initial conditions for planet formation in this special astronomy focus ...

A new planetary system is forming around the young star HOPS-315. Scientists observed the earliest stages of planet formation around another star. The process involves the cooling and solidifying of ...

The birth of a new solar system may have been caught on camera. About 1,400 light-years from Earth sits a young sunlike star surrounded by cooling gas and teensy silicate minerals. These mineral ...
