The director of SpaceX is developing a network of satellites above the Earth that could speed up web surfing and could provide access to isolated communities. And the most interesting thing about this project is that it will use the profits to help colonize the planet Mars.
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.
