A shell of icy objects at the edge of the solar system known as the Oort cloud has a pair of spiral arms that resemble a ...

We typically think of the Oort cloud as scattered ice balls floating far from the sun, yet still tied to it gravitationally.

The inner Oort cloud, between 1,000 and 10,000 AU from the sun, displays a spiral formation with arms that extend 15,000 AU.

Learn about the Oort cloud, a vast area beyond the inner solar system that is believed to contain icy objects arranged in a spiral shape.

The Oort Cloud begins roughly 2,000 – 5,000 astronomical units (AU) from the Sun, with 1 AU being the average distance between Earth and the Sun.

New research suggests the Oort cloud, a shell of icy objects at the edge of our solar system, may feature spiral arms similar to the Milky Way, revealing a complex cosmic structure beyond Pluto.

Most of the long-period comets in the Solar System come from the outer Oort Cloud. The inner region is much more stable. It's closer to the Sun, which means it's more strongly bound by the Sun's ...

The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it ...

The giant cloud of detritus is thought to be the source of strange comets and meteorites flying past Earth such as the ...

But what the Oort cloud actually looks like and how it is affected by forces greater than just our solar system has remained somewhat of a mystery. A new paper posted to the arXiv preprint server ...

A hidden structure at the farthest reaches of our solar system is challenging long-held theories. Using advanced simulations, ...

SpaceX on Monday will launch a Falcon 9 rocket into low-Earth orbit outfitted with 21 Starlink satellites, 13 of which will ...
