Evidence that rocky planets beyond Jupiter formed as rapidly, and at the same time, as the inner planets could transform our ...

This process, called accretion, is how everything in the solar system – planets, moons, comets and asteroids – came into being. Telescopes can see young solar systems being born.

The astronomers observed hot minerals just beginning to solidify – the first specks of planet-forming material, the ...

They detected silicon monoxide gas as well as crystalline silicate minerals, the ingredients for what’s believed to be the first solid materials to form in our solar system more than 4.5 billion ...

Weighing in at 0.6 solar mass, HOPS-315 should someday grow to become a star much like our own sun; this makes it a promising stand-in for studying the first stages of our solar system’s history.

Analysis of an ancient meteorite suggests that rocky planets both near and distant from the sun may have formed at the same time, challenging current models of our solar system’s evolution.
