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 ...

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 miniature galaxy, new research suggests.

The Oort cloud is thought to be a remnant of the solar system’s formation, a shell of icy debris left over from the chaotic ...

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 ...

The Solar System continues to surprise us day after day and its presence in terms of dominance and expansion goes far beyond ...

At the edge of our solar system, a host of large, icy bodies make up the Oort cloud, which appears to sport two spiral arms reminiscent of a disk-shaped galaxy. New research founded upon a simulation ...

Groundbreaking research reveals the Oort Cloud's shape as a spiral structure, challenging traditional beliefs about its random collection. NASA's Pleiades supercomputer simulations suggest the ...

The triple star system is sending comets, asteroids and meteors our way, and the number of interstellar objects entering the solar system will rise.

Previous research has suggested that the Oort cloud contains remnants of the solar system's planets, which were formed over 4 billion years ago, but its exact shape and structure have been a mystery.
