Space
A rocket carrying more than a dozen privately built probes touches down on the moon. The robots burst from the vehicle in a race to beam back high-definition video and other data while roving the surface of Earth's nearest natural satellite. The people of Earth watch a broadcast of the race as the rovers roam (or stall) in the lunar dust.
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.
