Comet C/2013 US10 (Catalina) was discovered on Oct. 31, 2013 by the Catalina Sky Survey. It reached perihelion on Nov. 15, 2015 and is currently visible in telescope views from Earth.
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.
