If you travel far enough away from the Sun, the Solar System becomes a lot more populated. Out past the orbit of Neptune lies the Kuiper Belt, a vast, ring-shaped field of icy rocks. This is where ...

A decade of observations with the Subaru Telescope in Hawaii has uncovered the existence of an intriguing cluster of objects at the edge of our Solar System. This could drastically shift our ...

A team combined compositional data of primitive bodies like Kuiper Belt objects, asteroids and comets with new solar data sets to develop a revised solar composition that potentially reconciles ...
