2001: A Space Odyssey introduced a lot of people to the idea of rotation based artificial gravity, but in sci-fi, it’s far from the only one to implement the idea! Babylon 5, Halo, and Ringworld also used rotation-based artificial...

I’m going to tell you about the craziest proposal for an astrophysics mission that has a good chance of actually happening. A train of spacecraft sailing the sun’s light to a magical point out there in space where the Sun’s own gravity...

Artist Ersin Han Ersin invites us to step inside a giant sequoia tree, peering through the bark into the tapestry of life within. Discover how his multisensory installations explore the concept of "umwelt," or the unique sensory...

A hydrogen atom is traveling high within the outermost layer of Earth's atmosphere. This particular atom first entered the exosphere millions of years ago, but today it overcomes Earth's gravitational pull and escapes, joining the...

Most of us are stoked if we can get a stone to skip more than 3 or 4 times. The world record holder at skipping stones has 88 skips. Here's why science says that number is way too low.

If you take a look at all the impact craters in our solar system, the vast majority are nice, neat circles. But why? Meteorites and asteroids strike planets and moons at all sorts of angles. Where are all the elliptical craters?

In the hunt for life beyond Earth, scientists shouldn't skip over frozen planets. In some cases, ice might actually help life evolve!

Nature can be pretty noisy, but there's some stuff that's just quiet all the time - right? Well, thanks to advances in audio equipment, researchers are finding out that everything from plants to bacteria have a lot more to say that we...

Have you ever longed to swim while wielding a longer snorkel? Well, there are a few reasons why they might be shorter than you'd like.

Lots of people want to clean up the Great Pacific Garbage Patch, and plastics have a huge impact on ocean environments. But marine wildlife are already adapting to our plastic waste, which means cleaning it up isn't as simple as just......

We think we know how mountains form. Plate tectonics causes rock to be pushed up at fault boundaries. Except that model is hard to prove, and a new study suggests it might actually be a lot more complicated.

When you live in the ocean, it can be hard to find ways to keep hidden from predators, or from your own prey. But these three animals have found clever ways to stay hidden, by using light to their advantage. One of them even /makes...

Lots of geological forces need to come together for continents to form, but they all require one ingredient: water.

Watch these amazing rewilding videos from our friends at Planet Wild, in which they’re saving Europe’s cutest bird from extinction or resurrecting a dying forest.

This video is about the physics of geosynchronous and geostationary orbits, why they exist, when they don't, when they're useful for communication/satellite TV, etc.

This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it's gravity, curved space) through to the concepts of how curved spacetime is represented by psuedo-Riemannian manifolds with...

For thousands of years, sailors have been telling stories of a mysterious phenomenon called dead water. Even after scientists figured out why it happens, it still affects swimmers today.

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...

Jewel beetles are pretty eye-catching with their glossy, bright coloration. But if you were a small creature that needed to avoid predators, you might think that eye-catching is the last thing you'd want to be. But it turns out that...

Around the world, there are lakes that disappear without warning. Then, suddenly without warning, they sometimes return! This vanishing and reappearing affect reveals some surprising connections. Learn all about it with Hank on this new...

Somewhere in the Pacific Ocean, there's a fish that's . . . a little different. Join us for a new episode of SciShow where Hank will tell you all about the Pacific Barreleye Fish and what makes it so mysterious....

Bright pillars of light... clouds of glowing dust... shimmering discs floating around the sun... signs of extraterrestrial activity, or is there a more rational and scientific explanation for this phenomenon?

One of the toughest materials known to science is made not by humans, but by nature... and it's inside of oysters.

Some animals live in pretty extreme places, but the lava cricket might be the most hardcore of them all. These crickets have only been observed right after volcanic eruptions, and scientists have questions, like “How does a flightless...
