Explore the origins of one of the coolest geologic formations in the world, West Africa's Richat Structure.

Things get weird under pressure.

In 1944, amateur astronomer Hisako Koyama's latest endeavor was sketching the sun's shifting surface. She spent weeks angling her telescope towards the sun and tracking every change she saw with drawings. Little did she know, these...

Historically, the union between Shiva and Parvati was a glorious one: a sacred combination which brought fertility and connection to all living things. Yet a rift had grown between these two forces. Setting out to prove the importance of...

So, today we're talking about African Pantheons. Now, you might say, that's ridiculous. Africa isn't a single place with a single pantheon, and we'd be fools to try and cover all that in an eleven minute video. You'd be right. Instead...

Our planet's diverse, thriving ecosystems may seem like permanent fixtures, but they're actually vulnerable to collapse. Jungles can become deserts, and reefs can become lifeless rocks. What makes one ecosystem strong and another weak in...

A meteor shower happens when rocks from space burn up in the atmosphere and make a beautiful light show! Lately, though, Squeaks has been wondering what would happen if one of those space rocks made it through the atmosphere to the...

This video is about why it's harder to successfully land spacecraft and landers and rovers on Mars than on Earth, or Venus, or the Moon, or Titan, or asteroids. It all comes down to atmospheric density! When...

While astronomers are busy searching for life beyond Earth, they’ve also started asking another question: If life seems so difficult to find, then why is our world so full of it? One answer might be overhead right now: the Moon!

The snow is really coming down where Jessi lives, so she and Squeaks decided to stay indoors where it's nice and warm and look back on some of the amazing things they've learned about winter! Grab a fuzzy sweater and a mug of cocoa and...

2020 marks two decades of people living and working about the ISS, and from fireballs to microgravity grown crystals, they've been keeping busy.

The Sun: an entity worshipped as a god throughout time and across cultures. The source of all life and sustenance for our little blue space rock, and also a force of unthinkable destructive power. But soon humanity will reach out its...

Even science can't yet explain these 7 extremely cool, weird phenomena in the universe, despite decades or even centuries of research.

We all share one planet -- we breathe the same air, drink the same water and depend on the same oceans, forests and biodiversity. economist Naoko Ishii is on a mission to protect these shared resources, known as the global commons, that...

We've found plenty of dinosaur bones all around the world, but is it possible to find any fossilized soft tissues from ancient animals?

Want to learn more about the topic in this week's video? Here are some key words/phrases to get your googling started: - Lifting Condensation Level (LCL): The altitude at which the water vapor in rising air begins to condense - Adiabatic...

Foraminifera - tiny, single-celled marine life forms - build gorgeous houses that record how much ice there is on the planet.



FYI: We try to leave jargon out of our videos, but if you want to learn more about this...

In this video Paul Andersen explains why astronauts are weightless. He also explains how Newton's Universal Law of Gravitation can be used to calculate the gravitational force between objects.

The black hole at the center of the Milky Way is quiet now, but new evidence suggests that it woke up around 3.5 million years ago. And Enceladus may have the the building blocks of the building blocks of life.

Extreme environments full of life on Earth have led researchers to expand the definition of habitability to something that includes many more planets, potentially leading us to evidence of living things in a dramatically shorter time!...

Legendary ocean researcher Sylvia Earle shares astonishing images of the ocean -- and shocking stats about its rapid decline -- as she makes her TED Prize wish: that we will join her in protecting the vital blue heart of the planet.

Astronomers have found the first asteroid orbiting closer to the Sun than Venus, and recently, some scientists have been looking at Earth, trying to understand the origins of our protective magnetic field.

As computers have gotten more powerful, they’ve completely transformed how we explore the solar system. And along the way, the space industry has given computer science a boost too.

The Pioneer 10 and 11 probes were launched to explore outer space, but in the 80s scientists discovered they were veering off-course, and we had no idea why!
