Is there an equation for intelligence? Yes. It's F = T ∇ Sτ. In a fascinating and informative talk, physicist and computer scientist Alex Wissner-Gross explains what in the world that means.

Over the course of history, we've discovered hundreds of thousands of asteroids. But how do astronomers discover these bits of rock and metal? How many have they found? And how do they tell asteroids apart? Carrie Nugent shares the story...

Our star continuously throws out streams of charged particles at more than 500 kilometers per second, something we call Solar Wind. And just like regular weather can be unpredictable and dangerous, space weather can be, too. Meanwhile,...

Astronomers may have figured out some cool geology on Pluto, and Barnard's star is back in the running for having a planet!

The United Arab Emirates is planning an enormous colony on Mars, but first they are building the biggest Mars simulator right here on earth.

The universe gets a little weirder, and more dangerous, every time we study it. Understanding space weather, which can mess with our communications systems, will take strategic planning to monitor.

A volcanic eruption and series of earthquakes in 2005 were important not because they did a great deal of damage to humans, but because they’re geologic evidence of where Earth’s next ocean will most likely pop up.

Hank gives us a summary of a strange new calculation, which estimates the total body mass of all the humans on earth.

It’s becoming harder and harder to categorize moons as moons.

A mini-lesson on cause and effect.

As of 2018, there are around 2.5 billion smartphone users in the world. If we broke open all the newest phones and split them into their component parts, that would produce around 85,000 kg of gold, 875,000 of silver, and 40,000,000 of...

In this captivating video narrated by astrophysicist Neil deGrasse Tyson, viewers are taken on a journey through the history of the universe, from its explosive beginnings to the evolution of life on Earth. Through a mix of science and...

The record for the fastest thing ever created by humans is a tie between the Helios 2 probe and a manhole cover.

May 23rd, 1967 could have been the beginning of the end - all thanks to the sun.

Jupiter has a bunch of asteroids that are trapped in two specific points in its orbit!

We're used to talking about planets as spherical objects, but a donut-shaped planet is theoretically possible. What would life be like on one of these?

Scientists have worked out how likely it is that distant planets can see earth, and we are learning new ways to study the magnetic fields of galaxies.

Have you ever looked up at night and seen a streak of light flash across the sky? Some people call that a "shooting star," but it's not actually a star at all! Join Jessi and Squeaks to learn what shooting stars really are and how they...

Today we're going to talk about SPAAAAAACE, but not like stars and satellites and stuff. Instead, we're going to talk about geographic space. In geography, we can look at the world and the places and spaces we inhabit with four distinct...

The rumors are true! There's an Earth-like planet orbiting our neighboring star!

It's tricky to study the particles of our Sun because Earth’s magnetic field deflects them, but scientists have found ways to do it! They're helping us understand things like the Sun’s origin, what it's made of, and how it might affect...

New discoveries into two weird things that may have played havoc with the ancient solar system: dark matter and a wandering star.

What does it really take for a planet to be habitable? It turns out, certain parts of a star system, a galaxy, and even the universe as we know it, are more habitable than others. Get to know them as Hank takes you on a tour of some of...

During most of the past 2 million years or so, there were several species of hominins on Earth at any given time. Like, you might be familiar with our famous extinct cousins, the Neanderthals. But since 2010 we’ve been uncovering...
