In Juelich, Germany scientists from the German Aerospace Center have put together a collection of 149 xenon short-arc lamps within a protective radiation chamber. These lamps form the world’s largest artificial sun. The structure itself is 45 feet by 52 feet. The artificial sun is called Synlight.
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.
Omg this is epic
