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.

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

How Did the Solar System Form? The tale of our sun may begin with another star: a predecessor whose fiery death brought about the birth of our solar system.

The finding, published last week in The Astrophysical Journal, will help scientists more accurately understand stars and planets beyond our solar system formed and evolved across billions of years.

An accidental discovery in an astronomy show offers researchers a new clue about the mysterious Oort Cloud, a large expanse of icy bodies revolving around the sun.

Observations of a young star offer a glimpse of the high-temperature conditions that shaped rock formation in the early Solar System.

Astronomers have observed an object that originated from beyond our solar system, thought to be an interstellar comet, speeding through our celestial neighborhood.

The solar system consists of eight planets, several dwarf planets, hundreds of moons, and billions of asteroids, comets and meteoroids.
