Why do we go to space? In the beginning of our space program, the answer had a lot to do with war and paranoia. But with the dawn of the space shuttle, that all changed. Where do we go from here?

The silence of the galaxy and the resulting Fermi Paradox has perplexed us for nearly 50 years. But our most recent surveys of the Milky Way finally allow us to draw scientific conclusions about the depressingly persistent absence of...

SciShow Space shares the latest news from around the universe, including new insights into the giant supercluster of galaxies that we call home, and the first "data baby" from Rosetta's rendezvous with a comet.

When astronauts go into space, they're not always going alone.

Eric Giler wants to untangle our wired lives with cable-free electric power. Here, he covers what this sci-fi tech offers, and demos MIT's breakthrough version, WiTricity -- a near-to-market invention that may soon recharge your cell...

This video explores how various animals throughout evolutionary history have managed to grow to gigantic sizes through unique adaptations and environmental factors. From megabugs benefiting from a spike in atmospheric oxygen levels to...

Deep below the surface, the ocean floor is full of riches. There’s gold, iron, and lots of other rare, precious metals. What kind of geochemical processes can leave loot all over the seafloor?

Every environment on the planet -- from forested mountaintops to scorching deserts and even the human gut -- has a microbiome that keeps it healthy and balanced. Ecologist Steven Allison explores how these extraordinarily adaptable,...

We're going to be building on the Moon this decade -- and next will be Mars, says space architect Melodie Yashar. In a visionary talk, she introduces her work designing off-world shelters with autonomous robots and 3D printers and...

Every amazing mission you know about today started off as just an idea, and some of 2019’s early phase NIAC concepts could mean big things for our future.

Elementary particles are the smallest known building blocks in the universe-and the neutrino is one of the smallest of the small. These tiny neutrinos can tell us about the furthest reaches and most extreme environments of the universe...

What happens when you set off a nuclear bomb in space? Turns out we have a pretty good idea, and it's not pretty. Learn about the science behind high-energy explosions in space.

Observing the effects of microbes using satellites can give us all sorts of useful information about life on Earth ... and other planets too.

It requires a certain attitude to brave the elements of Antarctica. Luckily, the Antarctic midge has a set of adaptations that fit the bill.

For the first time, we are forced to consider the real risk of destabilizing the entire planet, says climate impact scholar Johan Rockström. In a talk backed by vivid animations of the climate crisis, he shows how nine out of the 15 big...

Pandora was the first mortal woman, breathed into being by Hephaestus, god of fire. The gods gave her gifts of language, craftsmanship and emotion. From Zeus she received two gifts: the trait of curiosity and a heavy box screwed tightly...

Our best technology can send men to the Moon and probes to the edge of our solar system, but these distances are vanishingly small compared to the size of the universe. How then can we learn about the galaxies beyond our own? Yuan-Sen...

TeD Fellow Carrie Nugent is an asteroid hunter -- part of a group of scientists working to discover and catalog our oldest and most numerous cosmic neighbors. Why keep an eye out for asteroids? In this short, fact-filled talk, Nugent...

We all know space travel is pretty dangerous, but here are a few more things that you probably wouldn't have thought to look out for!

Asteroseismology allows scientists to explore stars with sound. It can help them figure out what a star is burning and even help pin down the age of stars!

SciShow News explains an ominous record that Homo sapiens just broke: the highest levels of carbon dioxide emissions, the leading factor in global warming. Hank explains what it means, and what we can do.

When stars die, they tend to take everything around them with them. But new evidence appears to show a planet orbiting a white dwarf, and we’re not sure how it survived! Plus, experiments designed to detect dark matter might be capable...

On SciShow News this week, Hank explains how it can rain on the sun and dives in to findings from the NASA twin study!
