Nothing Works the Way You'd Expect On the Moon you'd weigh a sixth of what you weigh now. On Jupiter, more than double. And on Venus, a single day lasts longer than its entire year, the Sun rises in the west, and nobody is entirely sure why.
Space Is Completely, Perfectly Silent If you've ever heard an explosion in a space film: that's fiction.
Sunsets on Mars are Blue On Mars, the daytime sky is pink. But at sunset? It turns blue. The same dust that makes Mars red all day long is what creates that cool blue glow around the sun as it sets. Space is full of beautiful surprises.
Did You Know? The Sun You See Isn't Really There Sunlight takes eight minutes to reach Earth. Every time you look up, you are seeing where the Sun was, not where it is. If it vanished right now, you wouldn't know for over eight minutes. And that star you're not quite seeing? You could fit 1.3 million Earths inside it.
Why the Sky Is Blue (But Sunsets Are Red) Sunlight looks white, but it's actually all colours mixed together. Blue light bounces around in the atmosphere, turning the whole sky blue. At sunset, light travels further and the blue scatters away — leaving only the warm reds and oranges.
The Moon That Never Turns Its Back The Moon spins at exactly the same rate it orbits Earth, so the same face always points our way. Not by chance. Earth's gravity slowly forced it into lockstep over billions of years. The far side existed for millennia as the closest mystery nobody could see.
Footprints on the Moon Will Outlast Almost Everything on Earth Neil Armstrong's bootprints from 1969 are still perfectly crisp on the Moon's surface. No wind, no rain, nothing to disturb them. Scientists think they could last tens of millions of years.
