Scientists have put forward a blueprint for a purely space-based system to solve the growing problem of space debris. The proposal will be used to detect objects, and a recently developed high-efficiency laser system will be used to track space debris and remove it from orbit.
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).
Images show surprise changes to the spacecraft as it interacted with the atmosphere.
