Jupiter could hold more than 1,300 Earths, yet it spins once in under 10 hours. At its equator, the cloud tops race along at over 40,000 km/h. That frantic rotation visibly squashes the planet: its equatorial diameter is about 7% larger than its diameter measured from pole to pole.
A large share of Earth's water molecules formed in the interstellar cloud that existed before the Sun was even born, more than 4.6 billion years ago. You are literally drinking a cosmic fossil.
By day, the Martian sky looks butterscotch because of fine dust hanging in the air. But at dusk, those same grains scatter blue light forward, creating a bluish glow around the Sun. Rovers have photographed these blue sunsets: the exact reverse of what we see on Earth.
