In the middle of a galaxy more than 2 billion light years from Earth, a black hole called PDS-456 spews radiation and ultra-fast winds. The gusts carry more energy per second than a trillion suns and blow outward in all directions at intensities high enough to stop stars from forming, pitting the galaxy in a huge, cosmic struggle with the mysterious force at its center.
It may sound like something from science fiction, but the phenomenon has been quantified for the first time by researchers at NASA and the European Space Agency.
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.
Whoa, dude!
