Scientists have discovered that there might be dark matter trapped inside the sun - and it could be the solar interior. The bold new theory suggests that a form of the mysterious particle - which has yet to be directly observed - is absorbed by the sun from the centre of our galaxy. And once inside, it affects the movement of heat within our solar system's star - which could explain why scientists have struggled to explain 'pressure waves' inside the sun.
The supermassive black hole is 40 million times as massive as the sun and powers a quasar that existed 700 million years after the Big Bang.
The asteroid zoomed by Earth at a perfectly safe distance of around 1.8 million miles (2.9 kilometers).
