Here's how to spot it and why it happens. 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 ...

Previous research has suggested that the Oort cloud contains remnants of the solar system's planets, which were formed over 4 billion years ago, but its exact shape and structure have been a mystery.

Narrator: Serious scientists, like myself, believe our solar system was formed by the collapse of a giant cloud of gas and rock and is held together by the gravitational pull of the Sun.
