The edge of the Solar System is a strange place, full of oddities we've only just begun to probe. But perhaps the oddest of all is the Oort Cloud, a vast field of icy debris extending out to 100,000 times the distance between Earth and the Sun.

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.

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,
