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.

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

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.

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

An Egyptian astronomer called Ptolemy (AD100-168) described one of the earliest ideas for how the Solar System is structured. Ptolemy’s model and many earlier ideas of the Solar System had the ...

They are all part of the Maine Solar System Model, a representation of the solar system that stretches 40 miles from the University of Maine in Presque Isle to Houlton. The 20-year-old model was ...

Long after the planets of the Solar System formed, catastrophic collisions continued, with a climax about 4 billion years ago during an interval called the Late Heavy Bombardment. The scars of ...

Such an automated system is said to be a useful tool to ... “The utilization of the U-net model for solar energy systems detection provides a data-driven and automated solution with enhanced ...

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

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.
