The first planet detected by the Gemini Planet Imager is 100 light-years away but shares many of the characteristics of an early Jupiter. Stanford physics Professor Bruce Macintosh, the lead investigator on the instrument, explains how this planet could help us understand how solar systems form.
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.
