Scientists with NASA's first asteroid sample return mission, OSIRIS-REx, are gaining a new understanding of asteroid Bennu's carbon-rich material and signature "spinning-top" shape. The team, led by the University of Arizona, ...
The planetary system around star HR8799 is remarkably similar to our solar system. It has four gas giants in between two asteroid belts. A research team led by RuG and SRON used this similarity to model the delivery of materials ...
Planet Nine is a theoretical, undiscovered giant planet in the mysterious far reaches of our solar system.
The mystery of some lava-like flows on Mars has been solved by scientists who say they are caused not by lava but by mud.
Let's start at the beginning. Before humans, before Earth, before any of the planets existed, there were baby planets—planetesimals. Coalesced from dust exploded outward by the solar nebula, these blobs of material were just ...

Our solar system has a king. The planet Jupiter, named for the most powerful god in the Greek pantheon, has bossed around the other planets through its gravitational influence. With twice the mass of Saturn, and 300 times ...
The Dishchii'bikoh meteorite fall in the White Mountain Apache reservation in central Arizona has given scientists a big clue to finding out where so-called LL chondrites call home. They report their results in the April ...
A model developed at the Faculty of Physics at the Technion, in collaboration with German scientists at Tübingen, explains the unique properties of Arrokoth, the most distant object ever imaged in the solar system. The research ...
What astronomers thought was a planet beyond our solar system has now seemingly vanished from sight, suggesting that what was heralded as one of the first exoplanets to ever be discovered with direct imaging likely never ...
