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.

A mysterious cloud of space rock and debris in the outer reaches of our solar system might resemble a miniature galaxy, a new study has claimed. The Oort Cloud, named after Dutch astronomer Jan Oort in 1950,

We typically think of the Oort cloud as scattered ice balls floating far from the sun, yet still tied to it gravitationally. Occasionally, some wayward gravitational perturbation will knock one of them a weird way and create a long-period comet,

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.

In the farthest reaches of our solar system, beyond the familiar planets and even the icy Kuiper Belt, lies a mysterious region known as the Oort cloud. This is a vast shell of icy bodies, stretching thousands of times farther from the Sun than Earth.

A hidden structure at the farthest reaches of our solar system is challenging long-held theories. Using advanced simulations, a NASA supercomputer has revealed that the Oort Cloud, a vast shell of icy bodies surrounding the Sun,
