SpaceX just launched a rocket to space and safely landed the first stage, in case you hadn't heard. The historic feat marks a huge shift in the private space industry, as the idea of a reusable rocket is now on the table.
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.
