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

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.

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