The Oort cloud is traditionally thought of as a vast shell of perhaps trillions of icy objects encasing our solar system, serving as the final boundary between us and the dark reaches of interstellar ...

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 ...

Most of our knowledge about the Solar System’s formation and evolution comes from the study of extraterrestrial rock samples called chondritic meteorites. These rocks, which are fragments of asteroids ...

The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it looks like. Now, new simulations may have given them a first glimpse. When you ...

The Oort cloud — the mysterious shell of icy objects at the edge of the solar system — might sport a pair of spiral arms that ...
