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 ...

How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by ...

A recent report details a waterless solar cleaning system design developed to address the challenge of dust accumulation on solar panels in arid regions; it is one of multiple waterless cleaning ...

Last month, Google quietly killed off Google Sky Maps. But there’s still another way to virtually explore most of the solar system a la Google Maps: it’s called Google Maps in Space. Google Maps in ...
