Orbiting between Mars and Jupiter is an enormous ring of space rocks. The region, known as the asteroid belt, is home to an estimated 1.9 million asteroids that are larger than 1 kilometer in diameter ...

NASA's Pleiades supercomputer has provided fresh insights into the Oort cloud – a vast, theoretical spherical shell of icy objects that surrounds our solar system. For a long time, the Oort cloud's ...

What lies beyond Pluto and the Kuiper Belt? Today we explore the Oort Cloud a vast, invisible shell of trillions of icy ...

Lying between Mars and Jupiter is a massive ring of rock debris—the asteroid belt. Now thin, it’s fading away gradually. In a new study, planetary scientist Julio A. Fernández of Uruguay’s Universidad ...

The asteroid belt is found orbiting between Mars and Jupiter and is a vast collection of rocks that is thought to be a planet that never formed. When our solar system formed 4.6 billion years ago, the ...

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 ...

An accidental discovery might change how we think about one of the most mysterious structures in our solar system. The Oort Cloud, a large expanse of icy bodies revolving around the sun at a distance ...

New research may shine a light on part of outer space's great mysteries: the Oort Cloud. The Oort Cloud is the name given to a theorized group of potentially trillions of icy objects on the edge of ...

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 ...

One million alien visitors from another star system could already be lurking in the solar system. We aren't talking about "little green men" here, however — more "little (and not so little) gray rocks ...

Astronomers searching for the faintest glimmers of light beyond distant Pluto say they’ve discovered a new dwarf planet – and that this planetoid’s movements hint that an invisible giant planet ...
