TED curator Chris Anderson shares his obsession with questions that no one (yet) knows the answers to. A short intro leads into two questions: Why can't we see evidence of alien life? And how many universes are there?

We only know 4% of what the universe is made up of. Can we also know what lies beyond our galaxy ... and if there are undiscovered forms of matter? Luckily, we have space messengers - cosmic rays - that bring us physical data from parts...

NASA releases a Giant Ballooon and we learn more about the Martian ice age!

When you learned about the Earth’s interior in school, you were probably shown a diagram that looked like a perfect layer cake. But we've known for a long time that that diagram is... inaccurate at best, and leaves out information that...

Geologists have a few ideas as to how rain affects mountains. But could rain also help mountains grow?

With their squishy bodies and color-changing abilities, octopuses and other cephalopods already look like our planet’s resident aliens. But researchers have discovered yet another thing that separates them from most other animals on Earth!

Scientists have discovered an underground lake of liquid water on Mars! While this isn’t itself evidence for life on Mars, it does raise some new possibilities.

As Earth’s climate changes, one of the hardest things to figure out is exactly how the planet will change in response. And while we can’t know the future for sure, we can get a lot of good clues from the past.

Dino stops by the Fort to learn all about dinosaurs with Jessi and Squeaks! Did you know that dinosaurs were on Earth for so long that not all dinosaurs lived at the same time?!



2nd Grade Next Generation Science...

Well, here we are. It's the final episode of Crash Course Film Criticism and we're going to chat about one of the more polarizing films ever made: Stanley Kubrick's 2001: A Space Odyssey. On the surface, 2001 tells the story of human...

In November 1986, Australian miners climbed Lunatic Hill and bored 20 meters into the Earth. They were rewarded with a fist-sized, record breaking gemstone, which they named the Hailey's Comet opal. Thanks to a characteristic called...

Photographer James Balog shares new image sequences from the Extreme Ice Survey, a network of time-lapse cameras recording glaciers receding at an alarming rate, some of the most vivid evidence yet of climate change.

The Hypatia stone is one of the weirdest rocks on the planet. It's not just out of this world, it might be out of this solar system!

What weird worlds are these video games creating?

Do 97% of climate scientists really agree that humans are the main cause of climate change? Yep! Here's what the 97 percent statistic *really* means.

Our first video ever! Agriculture, hula hoops, SARS, and THIS video: how long did they take to get around the earth?

Pulsars are more than just cool blinking lights shining across the universe. The discovery of the first binary pulsar paved the way for gravitational wave astronomy astronomy today.

While the Earth's oceans are known as five separate entities, there is really only one ocean. So, how big is it? As of 2013, it takes up 71% of the Earth, houses 99% of the biosphere, and contains some of Earth's grandest geological...

While comets were historically thought to be ill omens of war and famine, recent science has revealed that these celestial wonders actually contain amino acids, the building blocks of life on Earth. Justin Dowd explores the implications...

Solar Storms! Moaning Myrtle! Wondering what the frick is behind the solar flares that slammed Earth earlier this week? Hank lays out how that juicy ball of plasma we call the sun causes us trouble from time to time.

Dr. Emmett Chappelle developed a test to find living microbes on other planets, and while it hasn't yet been used to find life amongst the stars, we've found many applications for it here on Earth

Life on Earth has always been shaped by other bodies in space, and life in our oceans is especially susceptible to interactions that have huge effects on life as we know it!

Sending rockets into space requires sacrificing expensive equipment, burning massive amounts of fuel, and risking potential catastrophe. So in the space race of the 21st century, some engineers are abandoning rockets for something more...

How does an astronaut prepare physically and mentally to launch into space? NASA astronaut Megan McArthur, who traveled to the International Space Station in April 2021 as part of the SpaceX Crew-2 mission, shares stellar life lessons...
