A huge thank you to Prof. Geraint Lewis and Dr. Ashmeet Singh for helping us understand the applications of Non-Euclidean geometry in astronomy/cosmology.

Why Are Saturn’s Rings Younger Than Saturn?

AdultsEducationScienceSpace...
Saturn's rings are younger than Saturn, and the most spectacular sight in the Solar System is also disappearing. How do we know? By running our finger through some cosmic dust.

Why Is Our Moon Two-Faced?

So you know a bit about the Big Bang - but did you know that you can physically see or hear it in your every day life? Find out how 'static' often contains remnants from this monumental event.

The beginning of the universe, for beginners

AdultsHistorySpacePhysics...
How did the universe begin -- and how is it expanding? CERN physicist Tom Whyntie shows how cosmologists and particle physicists explore these questions by replicating the heat, energy, and activity of the first few seconds of our universe, from right after the Big Bang.

What Color is the Universe?

AdultsPhysicsSpaceAstronomy...
When you stare up at the night sky, you might think that the universe is really black, but that's just because our eyes aren't sensitive enough to see the billions and billions of multicolored stars out there. Ever wonder why certain stars are certain colors? And what color is our sun, really? If we looked at enough stars, could we figure out the average color of the universe?

Why Do We Only See One Side of the Moon?

AdultsScienceSpaceAstronomy
Only one side of the Moon is visible from Earth because the Moon rotates about its spin axis at the same rate that the Moon orbits the Earth, a situation known as synchronous rotation or tidal locking.

Dark matter: The matter we can't see

AdultsPhysicsSpaceScience...
The Greeks had a simple and elegant formula for the universe: just earth, fire, wind, and water. Turns out there's more to it than that -- a lot more. Visible matter (and that goes beyond the four Greek elements) comprises only 4% of the universe. CERN scientist James Gillies tells us what accounts for the remaining 96% (dark matter and dark energy) and how we might go about detecting it.
