Space.com: The New Horizons' team and a room full to capacity at the mission's control center outside of Baltimore, Maryland celebrated with the rest of the world at the exact time of the Pluto (7:49 EDT, July 14th, 2015).
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.
