From gigantic planets too close to their stars, to those in unfathomably wide orbits, astronomers have discovered seemingly impossible solar systems that shouldn’t exist at all. But they do.

SciShow News gives you some wet and weird developments from around the solar system, including new insights about what liquid lurks under the surface of Titan, and a sweaty comet that's been spotted on its way toward the sun.

Jessi and Squeaks are on a beach vacation, so they've called in their pal, Dr. Lawrence Turtleman, to take over the show for today! And what is he going to teach you about? Turtles, of course!

"We will start inhabiting outer space," says Angelo Vermeulen, crew commander of a NASA-funded Mars simulation. "It might take 50 years or it might take 500 years, but it's going to happen." In this charming talk, the TED Senior Fellow...

So how do astronauts manage to pee and poop in microgravity? And what happens to all of their waste? Do you really want to know? If you do, the answers are inside!

The apparent void in the darkness of space is not as empty as you might think. In fact, it somehow holds the key to creating stars, planets, and even us! And Dutch super-scientist Ewine van Dishoeck made it her life's work to figure out...

Welcome back to SciShow Quiz Show! In this episode Hank will be competing with older brother John Green in a battle of science related trivia on behalf of Subbable subscribers Anna Dilley & Andrew Villarreal.

Hank talks about astrobiology - the study of and search for life in the universe off Earth. Right now, the field has more questions than answers, but all they all seek to answer that one fundamental query: are we alone in the universe?

It’s not easy to find active plate tectonics on other worlds, but doing so may bring us one step closer to finding a planet that can support life.

The Crab Nebula is one of the most studied things in the sky, but it took glimpses through various wavelengths of the electromagnetic spectrum to get a full picture of what’s hiding inside!

Is it better to walk or run when it's cold out? If you run, then you have to deal with wind, wind chill, etc, but your body generates more heat. If you stay still, standing or walking slowly, you don't generate as much heat, but don't...

Oxygen levels in the Martian atmosphere are mysteriously inconsistent, and scientists don’t have a clear explanation for what’s behind the changes. Meanwhile, scientists DO have explanations for the tiger-like stripes on one of Saturn’s...

2016 was a lot of things, but for astronomers, it meant the discovery of some of the farthest, faintest, and youngest objects in the universe we've seen yet.

Two astronauts are about to embark on the One Year Mission which can help us understand more about the long-term effects of being in space, and there is an upcoming total lunar eclipse (the shortest one this century)!

What would it take to reimagine the limits of architecture? Débora Mesa Molina offers some answers in this breathtaking, visual tour of her work, showing how structures can be made with overlooked materials and unconventional methods --...

Radio host Julie Burstein talks with creative people for a living -- and shares four lessons about how to create in the face of challenge, self-doubt and loss. Hear insights from filmmaker Mira Nair, writer Richard Ford, sculptor Richard...

The True Science of Parallel Universes

Why is the past different from the future? Caltech physicist Sean Carroll explains how the arrow of time is not an intrinsic property of physics, but rather an emergent feature.

These days it seems almost trivial to cool atoms down to near absolute zero temperatures in a lab, but what is the lowest possible naturally occurring air temperature on this planet?

This video is about how life arose and what its main function or purpose in the universe seems to be. Thanks to Sean Carroll for collaborating on it! This video is about how life arose and what its main function or purpose in the...

This video is about Simpson's paradox, a statistical paradox and ecological fallacy where seemingly contradictory results are implied by a single set of data depending on how it's grouped. The paradox can arise in medical studies,...

Mister Brown teaches Squeaks all about engineering to help him solve a problem he is having! K-2 Next Generation Science Standards Science and Engineering Practices: Asking Questions and Defining Problems, Developing and Using Models,...

What do beavers, termites, and prairie dogs have in common? They all change their environments! Last time we talked about how humans change their environments, but humans are animals and all animals change their environments just by...

On a cosmic scale, Mercury isn’t very far away, but it's incredibly hard to get there. Getting into orbit around it takes years of flybys in the solar system, but we're going to do it again!
