TED-Ed: The incredible collaboration behind the International Space Station - Tien Nguyen
The International Space Station is roughly the size of a six-bedroom house and weighs more than 320 cars -- it's so large that no single rocket could have lifted it into orbit. Instead, it was assembled piece by piece while hurtling...

TED-Ed: Could we survive prolonged space travel? - Lisa Nip
Prolonged space travel plays a severe toll on the human body: microgravity impairs muscle and bone growth, and high doses of radiation cause irreversible mutations. As we seriously consider the human species becoming space-faring, a big...

TED-Ed: Meet the tardigrade, the toughest animal on Earth - Thomas Boothby
Without water, a human can only survive for about 100 hours. But there's a creature so resilient that it can go without it for decades. This 1-millimeter animal can survive both the hottest and coldest environments on earth, and can even...

TED-Ed: Could comets be the source of life on Earth? - Justin Dowd
While comets were historically thought to be ill omens of war and famine, recent science has revealed that these celestial wonders actually contain amino acids, the building blocks of life on Earth. Justin Dowd explores the implications...

TED-ED: Climate change: Earth's giant game of Tetris - Joss Fong
There's a game of Tetris happening on a global scale: The playing space is planet Earth, and all those pesky, stacking blocks represent carbon dioxide -- a greenhouse gas that is piling up ever more rapidly as we burn the fossil fuels...

TED-ED: Why is NASA sending a spacecraft to a metal world? - Linda T. Elkins-Tanton
In 2026, an unmanned NASA spacecraft is scheduled to arrive at 16 Psyche, a massive, metallic asteroid floating somewhere between the orbits of Mars and Jupiter. Why is NASA so interested in this heavy metal asteroid? Are we going to...

TED-Ed: Free falling in outer space - Matt J. Carlson
If you were to orbit the Earth, you'd experience the feeling of free fall, not unlike what your stomach feels before a big dive on a roller coaster. With a little help from Sir Isaac Newton, Matt J. Carlson explains the basic forces...

TED-Ed: Where did Earth's water come from? - Zachary Metz
Water covers over 70% of the Earth, cycling from the oceans and rivers to the clouds and back again. It even makes up about 60% of our bodies. But in the rest of the solar system, liquid water is almost impossible to find. So how did our...

TED-Ed: Is space trying to kill us? - Ron Shaneyfelt
How likely is it that a massive asteroid will do major damage to Earth and its inhabitants? What about the sun -- is it dying out anytime soon? And the supermassive black hole at the center of the Milky Way -- should we be worried about...

TED-Ed: Cloudy climate change: How clouds affect Earth's temperature - Jasper Kirkby
As the Earth's surface temperature gradually rises, it has become vital for us to predict the rate of this increase with as much precision as possible. In order to do that, scientists need to understand more about aerosols and clouds....

TED-ED: Who won the space race? - Jeff Steers
On October 4, 1957, the Soviet Union launched the satellite Sputnik and, with it, an international space race. The United States and the Soviet Union rushed to declare dominance of space for 18 years, until the two countries agreed to a...

TED-ED: The fundamentals of space-time: Part 3 - Andrew Pontzen and Tom Whyntie
In the first two lessons of this series on space-time, we've dealt with objects moving at constant speeds, with straight world lines, in space-time. But what happens when you throw gravity into the mix? In this third and final lesson,...

TED-Ed: The fundamentals of space-time: Part 1 - Andrew Pontzen and Tom Whyntie
Space is where things happen. Time is when things happen. And sometimes, in order to really look at the universe, you need to take those two concepts and mash them together. In this first lesson of a three-part series on space-time,...

TED-Ed: The fundamentals of space-time: Part 2 - Andrew Pontzen and Tom Whyntie
Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time,...

TED-Ed: What on Earth is spin? - Brian Jones
Why does the Earth spin? Does a basketball falling from a spinning merry-go-round fall in a curve, as it appears to, or in a straight line? How can speed be manipulated while spinning? In short, why is the spinning motion so special?...
