“Building one space station for everyone was and is insane: we should have built a dozen.” -Larry Niven From Earth and beyond, these time lapses show our one-of-a-kind motion through the Universe. Here on Earth, the night sky (and all the stars in it) appear to rotate a full 360° every 24 hours, producing star…

Ask Ethan #25: Where would you go, now?

Where is Everybody? (Part II)

“If the Universe Is Teeming with Aliens… Where Is Everybody?” -Stephen Webb It’s one of the biggest conundrums in the Universe, known as the Fermi Paradox: if the Universe is so conducive to life, and if there are so many opportunities for it within our galaxy alone, why isn’t there any evidence (outside of the…

Rocks remember, and so do we

“Geologists have a saying: rocks remember.” -Neil Armstrong Looming up above us, hundreds of thousands of miles away, is the largest moon in the inner solar system: our Moon.
