Scientists from the Lawrence Livermore National Laboratory recently announced that research indicates our solar system formed in less than 200,000 years. On a cosmic scale, that is very fast.

To unravel the mystery of Jupiter's birth, scientists turned their attention to meteorites. These cosmic 'messengers' carry a ...

Researchers have laid out a new, comprehensive theory for how the solar system formed — inside the bubble of a long-dead, giant star.

Two of the most mysterious planets in our solar system are Uranus and Neptune. These planets are also known as ice giants, due to their intermediate-mass and size which suggests an ice-rich ...

Standard planet-formation models have been unable to reconstruct the distributions of the Solar System's small, rocky planets and asteroids in the same simulation. A new analysis suggests that it ...

The initial solids from which the solar system formed consisted almost entirely of carbon, ices, and disordered (amorphous) silicate, the team concluded.

“The gas giants must have formed by 4 million years after the formation of the solar system,” Weiss says.

If the solar system formed from this material, this alternate scenario would account for the abundances of both isotopes. “In the future, this study must be considered when people build their story ...

Since the first discovery of planets beyond the solar system in 1995, more than 6,000 exoplanets have been identified. Many ...

A new theory of the solar system's formation provides an alternative to the idea our system formed from a supernova.

The samples, which were scooped up by NASA's OSIRIS-REx spacecraft during a brief yet dramatic touchdown on Bennu in 2020, ...
