Food already in cupboards, supermarkets, & warehouses could feed humanity for 4 months, but potential food - berries, termites & krill - could extend that by another...

NASA's Dragonfly -- a robotic rotorcraft-lander that's designed to hop across the surface of an extraterrestrial body -- is set to voyage deep into the solar system to explore Titan, Saturn's largest moon, in 2026. Planetary scientist...

Scientists have revealed the results of the Parker Solar Probe’s first two flybys of the Sun, and LIGO has a new instrument called the quantum vacuum squeezer!

SciShow Space gives you a blow by blow account of what's going to happen to the sun -- and Earth.

Explaining strange Earth geology is often straightforward — combine a volcanic eruption a dash of erosion, and boom, you’ve got a striking cliff! But not all the features on this planet are so easy to figure out. From the ground randomly...

Fossils can provide clues to the conditions that ancient species lived in, like what their environments felt like, how deep in the water some species lived, or even how long the Sun was out!

We’ve developed thousands of technologies for space exploration, but luckily for us, sometimes those solutions apply to problems here on the ground, too.

Astronomers took advantage of a lunar eclipse to study Earth as if it were an exoplanet, and Mars's Insight lander used seismic data to reveal for the first time boundaries between different layers of Mars.

Hank gets to the bottom of an exciting, and kinda weird, announcement from Russian scientists at the Vostok Research Station in Antarctica. Have they reached a 20-million-year old underground lake? Maybe! Is there a hoard of Nazi secrets...

Hank explains the enormity of the Giant Magellan Telescope, possibly the biggest telescope ever built, as well as updates about NASA's new mission to the moon, and an unusual discovery about the habits of deep-sea squid.

Earth has its share of monster storms, but even our most powerful hurricanes are a breeze compared to the great, planet-sized tempests of the gas giants.

Trilobites are famous not just because they were so beautifully functional, or because they happened to preserve so well. They're known the world over because they were everywhere!

Garik Israelian is a spectroscopist, studying the spectrum emitted by a star to figure out what it's made of and how it might behave. It's a rare and accessible look at this discipline, which may be coming close to finding a planet...

There are a lot of nuclear weapons on Earth, so many that we often say it's enough to "destroy the world several times over." But could we? Well, that depends on what you mean. Also...no matter what you mean, probably not. The Earth is...

You might think of plate tectonics as destructive since it's the ultimate force behind earthquakes, tsunamis, and volcanic eruptions. But the slow movement of our planet's surface does a lot more than shake things up now and then. Some...

Whether it's robots under the sea, wave detectors in space, or star-power on land, this episode has big experiments covered.

Here it is, folks: the end. In our final episode of Crash Course Astronomy, Phil gives the course a send off with a look at some of his favorite topics and the big questions that Astronomy allows us to ask.

Temnospondyls were a huge group of amphibians that existed for 210 million years. And calling them 'diverse' would be putting it mildly. Yet in the end, two major threats would push them to extinction: the always-changing climate and the...

Oxygen is crucial for life as we know it, but before it could build up in our atmosphere, earth had to slow down.

Coming to us from 50 years in the future, legendary sci-fi writer Kim Stanley Robinson tells the "history" of how humanity ended the climate crisis and restored the damage done to Earth's biosphere. A rousing vision of how we might unite...

Last week, NASA released some pretty cool Mars news: Curiosity found even more evidence to indicate the planet could’ve been habitable billions of years ago.

There is a chemical reaction discovered a century ago that could be the key to creating everything from fuel to shelter on Mars!

Evolution has come up with some pretty amazing ways to get things done when it comes to animals, plants and microbes. From radiation-resistant bacteria (like Dr. Manhattan) to geckos who climb glass using atomic adhesion (like Spider...

In a talk about how we can build a robust future without wrecking the planet, sustainability expert Johan Rockstrom debuts the Earth3 model -- a new methodology that combines the UN Sustainable Development Goals with the nine planetary...
