The earth is our home, and while we like to think we know a good deal about it, there are still some mysteries that scientists are looking to unravel. Chapters PLATE TECTONICS 1:45 EXTROVERSION Sponsored by: Jonathan Hood 3:50...

Earlier this spring NASA announced a new research model that predicts that ocean worlds are far from rare, and our galaxy might be full of them. And a new study examines evidence that Pluto may have had an underground ocean all along!

Astronomers have theorized about an invisible star made up of theoretic particles in the past, but did we recently detect the gravitational waves of two of them colliding? Plus, extraterrestrial rocks from a decades-old mission keep...

Paul Andersen explains how the behavior of various organisms is shaped by natural selection. The action of phototropism and the timing of photoperiodism have both been shaped by the relative availability of light. Courtship in the bower...

While we like to imagine little green men, it's far more likely that life on other planets will be microbial. Planetary scientist Nathalie Cabrol takes us inside the search for microbes on Mars, a hunt which counterintuitively leads us...

Pluto's heart is revealing itself to be a major influence on the dwarf planet’s landscape and atmosphere, and scientists used atom probe tomography (APT) for the first time on lunar soil to study it atom by atom!

Deep below the surface, the ocean floor is full of riches. There’s gold, iron, and lots of other rare, precious metals. What kind of geochemical processes can leave loot all over the seafloor?

You need it, you love it, you probably live on it: it's land! But have you ever thought about where land even comes from?

You may have read that 2018 is looking to be a bad year for earthquakes, but Hank is here to offer you some assurances.

Even though there are no volcanoes on the Olympic Peninsula, you can find lots of volcanic rocks on the beaches. This bizarre circumstance might have to do with how the ancient island transformed Washington state.

It's easy to take things at face value in video games. But when we take a deeper dive into the physics in The Legend of Zelda: Majora's Mask, it seems that the "MOON" might be one of those things that isn't quite what it seems. Given its...

Modern-day Ohio is more than 600 kilometers from the ocean - yet it has thousands of ocean fossils dating back to the Ordovician, giving us a glimpse at its past under an ancient, fishless sea.

For upside-down mirrors, super hot volcanic chimneys, and neon rocks with living microorganisms, look no further than the Guaymas Basin in the Gulf of California.

Blue Origin announced a a new lunar lander, Blue Moon, that will be delivering supplies, and eventually astronauts to the lunar surface within the next 5 years, and robots like Chang’e-4 are giving us an early glimpse at what we might...

Earth isn't the only planet that gets rocked by giant tsunamis. In fact, giant waves on other planets have helped us solve a few mysteries about our solar system.

In this video Paul Andersen describes several types of evidence for common ancestry. This evidence is contained in the fossils, embryos and molecules of living organisms. Even though life on our planet is incredibly diverse there are...

Every day, we make decisions that have good or bad consequences for our future selves. (Can I skip flossing just this one time?) Daniel Goldstein makes tools that help us imagine ourselves over time, so that we make smart choices for...

"When it comes to extinct creatures like dinosaurs, it can be tough to know for sure what they actually ate. And we’d like to know because what an animal eats tells you a lot about it. But every now and then, the fossil record gives us a...

Plutonium powered robot car! With a laser gun! That's (kind of) what's hurtling through space right now as part of NASA Mars Science Laboratory heads for the Red Planet. Hank walks you through this historic mission, with the help of some...

NASA’s Magellan mission gave us unprecedented insight into Venus’s rocky surface, and even now, more than 25 years after the mission ended, it’s still one of our main tools for learning about our mysterious, next-door neighbor.

Megatsunamis are not only much larger than your average tsunami, they also form under different conditions. Good news: they're extremely rare. Bad news: they might not be for long.

We’ve been sitting on samples of the lunar surface for decades and, with better technology than when they were taken, we are opening them back up to take another look!

If salty water is constantly spilling into the world’s oceans, does that mean they are getting saltier by the day?

Sometimes, in order to learn something, you've got to punch a giant asteroid.
