Asteroid mining is considered by many to be a key to the colonization of outer space, the space equivalent of California's Gold Rush. Nearly 9,000 asteroids larger than 150 feet (46 meters) in diameter orbit near Earth. These asteroids are prime for mining precious metals like platinum and are a source for water in space, essential for a space outpost.
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.
