A mysterious cloud of space rock and debris in the outer reaches of our solar system might resemble a miniature galaxy, a new ...

New research suggests the Oort Cloud may have a spiral structure like a mini galaxy. Supercomputer models reveal its ...

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

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.

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

What they found was surprising: the inner Oort Cloud seems to form a spiral disk, stretching about 15,000 astronomical units (AU) long. 1 AU is the distance between the Sun and the Earth (149.4 ...

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

Sure, they’re particles and rocks, but they’re still a fascinatingly long way from home. Alpha Centauri is the star system ...

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 looks like. Now, new simulations may have given them a first glimpse.
