The Oort cloud, a theoretical spherical shell surrounding our solar system, extends from approximately 1,000-2,000 AU to potentially 100,000 AU, halfway to Alpha Centauri. Its existence is inferred ...

If the Oort Cloud is three light years away from our Sun, then it's closer to Alpha Centauri than our Sun, right? So how can it stay around our Sun if the mass of Alpha Centauri is 1.1 times the mass ...

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 ...

In the farthest reaches of our solar system, beyond the familiar planets and even the icy Kuiper Belt, lies a mysterious ...

The Oort cloud is a shell of icy bodies that surrounds the solar system. It begins beyond the Kuiper Belt and even beyond the influence of the sun’s magnetic field, technically in interstellar space.

The Oort cloud is a shell of icy objects that forms the very outskirts of our Solar System. Recently, a group of researchers discovered that the inner portion of the Oort cloud likely has spiral arms ...
