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.

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.

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 mysterious cigar-shaped rock known as Oumuamua that was spotted in October 2017.

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

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 ...

Researchers claim that there could be at least 1 million interstellar objects hiding in the Oort Cloud at the edge of our ...
