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.

Early in our Solar System’s history, bits of icy debris were scattered and then gradually coaxed into a spiral alignment in ...

DALLASI absolutely love this, it's called an orrery, and it's a little mechanical model of our solar system. You can see the planets here, orbiting the sun as they would do in real life.

Interstellar material has been discovered in our solar system, but researchers continue to hunt for where it came from and ...

Could a giant planet between Mars and Jupiter have doomed Earth? A new study suggests that small changes would have been ...

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 spiral ...

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.

New research suggests the Oort Cloud may have a spiral structure like a mini galaxy. Supercomputer models reveal its mysterious shape, offering new insights into the edge of our solar system.
