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.

NASA’s Pleiades supercomputer has provided fresh insights into the Oort cloud – ​​a vast, theoretical spherical shell of icy objects that surrounds our solar system. For a long time, the Oort cloud’s appearance has been unknown.

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,
