A small, cool star is emitting flares 10,000 times brighter than those ejected by the sun, a find that could be bad news for those hoping to find the galaxy filled with life.
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.
I wonder whether the star is still alive!
