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

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 ...

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.

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

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 ...

They noted that any larger asteroid formed very early on in the solar system would have been heated to high temperatures by the decay of large amounts of aluminum-26, a radioactive nuclide ...

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