In an off-planet exploration first, the Mars Science Laboratory has investigated an active sand dune. The work is being performed to understand the physics and composition of the moving sand.
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.
