NASA supercomputer reveals strange spiral structure at the edge of our solar system

75% Informative
The Oort cloud is the mysterious shell of icy objects at the edge of the solar system.
Its inner edge sits roughly 2,000 to 5,000 astronomical units from the sun.
Its outer edge is located between 10,000 and 100,000 AU away from our solar system's sun.
A new model suggests the inner structure of the cloud may look like a spiral disk.
To confirm this structure, researchers will need to track the objects directly or pick out the light reflected from them.
