Building Stuff: Change It! Preview
Humans have been altering Earth’s environment for thousands of years. And now, from electric planes to artificial noses, engineers are inventing new ways to preserve our planet.
Building Stuff: Reach It! Preview
Born to explore, we’re constantly inventing new ways to go beyond our comfort zones. From deep sea subs to next-gen space habitats, see how engineers are building the tools humans need to go where we’ve never gone before.
Creating a Robotic Double Dutch Machine
Double Dutch is a jump rope game that requires two people spinning ropes in opposite directions and at least one person to jump. Engineers Tahira Reid Smith and Sky Leilani are building a machine that would allow a single person to play whenever they wanted.
Building Stuff: Boost It! Preview
How are leading innovators supercharging our natural abilities? From slingshots that can throw rockets into space to the latest in artificial sight, see how engineers are amplifying the human body’s powers.
Decoding the Universe: Quantum Preview
When we look at the world at the tiniest scales, things get very weird. Take a wild ride through the quantum world, from the discoveries that reveal its strange rules to the amazing technologies it unlocks – with more powerful possibilities to come.
Sir Arthur C. Clarke's Vision of the Computer-Dominated Future
Sir Arthur C. Clarke was a British science-fiction author who co-wrote the screenplay for 2001: A Space Odyssey.
How Medieval Armorers Made Knights Bulletproof
A select few suits of armor were crafted with secret techniques that made them stronger than others, possibly even bulletproof. Historians and ballistics experts reconstructed the amor of an elite knight and tested its strength by shooting it with a musket.
How Do Hurricanes Form?
Scientists predict that our increasingly warmer atmosphere and oceans will feed these hurricanes — we may not see more of them that we used to, but the ones we do see are likely to get more and more intense.
Could Mars Have a Ring Around It One Day?
Phobos, one of Mars' moons, has an uncertain origin, but its surface grooves show that tidal forces are pulling it apart. In time, Mars' gravity will shatter it entirely, creating a ring of debris around the planet.
Cameras Capture Earthbound Meteorite
In 2021, cameras recorded the fall of the Winchcombe meteorite, allowing scientists to trace its cosmic origin.
Solar System: Wandering Worlds Preview
From meteorites that impact Earth, to a moon that orbits backwards, to an imposter lurking in the asteroid belt, a variety of strange, wandering worlds are rewriting what we know – and even how we think about – our solar system.
This Moon May Have the Ingredients for Life
Europa is such a strong candidate for life that NASA launched a mission to explore the moon.
Why Do Comets Have Tails?
Worlds that exist close to the warmth of the sun, like the rocky worlds of Mars, Earth and our moon, have relatively little ice, because they lie inside what is known as the ice line.
Solar System: Icy Worlds Preview
Out in the solar system, ice can get bizarre. Visit strange, frozen worlds – from Uranus’s ultra-hot superionic ice, to glaciers of nitrogen ice on Pluto, to carbon dioxide snow on Mars – and discover why the ice here on Earth is so unique.
Could This Icy Moon’s Ocean Support Life?
Enceladus has jets rich in phosphates and likely hydrothermal vents in its ocean. With the key ingredients for life on its surface, the moon may serve as an incubator for life.
Enceladus: A Frozen Moon With Explosive Eruptions
Enceladus erupts over 660 pounds of water per second, with jets reaching up to 6,000 miles into space. These massive plumes far exceed the size of the moon itself.
This Tiny Moon Is a Volcanic Powerhouse
Jupiter’s small moon Io is the most volcanically active body in our solar system, with constant eruptions reshaping its surface daily.
Solar System: Volcano Worlds Preview
Around our solar system, violent eruptions are shaping distant worlds. Discover the explosive forces that helped create some of the most dynamic worlds in our cosmic neighborhood – and what makes the volcanoes right here on Earth so special.
How a Walnut-Shaped Moon Help Shape Saturn’s Rings
Shaped by gravitational forces over millions of years, Saturn's rings are incredibly complex. A tiny moon named Pan, just 17 miles wide, has notably influenced their structure by creating the Encke Gap.
Why is Haumea Shaped Like an Egg?
Haumea is one of the fastest rotating large objects in our solar system. A single day on the dwarf planet is only about 4 Earth hours long.
