NASA's Magnetic Multiscale mission, or MMS, consists of a fleet of four identical satellites studies three phenomena in Earth’s magnetosphere: magnetic reconnection, energetic particle acceleration, and turbulence. These processes occur everywhere in the universe but can only be effectively studied close to Earth.
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.
