Launched in 1997, NASA’s Voyager spacecraft has been traveling ever since, and it was around 167 astronomical units (AU) away from Earth. It was the first spacecraft to go beyond the heliosphere, ...

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 ...

The human mind may find it difficult to conceptualize: a cosmic cloud so colossal it surrounds the Sun and eight planets as it extends trillions of miles into deep space. The spherical shell known as ...

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 ...

Earth could be peppered with deadly wayward comets in just over a million years' time when a wandering star enters the outer reaches of the Solar System. Popular culture is full of cosmic doomsday ...

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

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 ...
