The Kuiper belt, a disc of icy rocks on the outermost edges of the solar system, seems to have more structure than we thought. In 2011, researchers found a cluster of objects there on similar orbits ...

"If our solar system is indeed moving this fast, we need to question fundamental assumptions about the large-scale structure of the universe." Astronomers have discovered that the solar system may be ...

If you've ever wondered why we are here, then you can thank Jupiter for part of the answer. A new study from Rice University suggests that if it weren't for the gas giant, the Earth would have ...
