Add up the diameters of Mercury, Venus, Mars, Jupiter, Saturn (without its rings), Uranus and Neptune and you get about 380,000 km. When the Moon is at its farthest, the gap between its surface and ours exceeds 390,000 km. Lined up side by side, the seven other planets would fit in that space. At the average distance, though, they would not quite make it.
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.
