The spacecraft Rosetta is now orbiting the Comet 67P/Churyumov-Gerasimenko. It's taking some amazingly clear images including the one above, the first ever close up of a the surface of a comet in history. Soon we will be landing there. According to NASA:
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.
