The Moon spins on its axis at exactly the same rate it orbits us, so it always shows us the same face. But the other side gets just as much sunlight! At new moon, when we see almost nothing, the far side is in full daylight. It's hidden from us, not from the Sun.
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.
