You don't need to be a professional astronomer to find new worlds orbiting distant stars. Darwin mechanic and amateur astronomer Andrew Grey this week helped to discover a new exoplanet system with at least four orbiting planets.
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).
