In the middle of the South Pacific lies Point Nemo: the most remote location on Earth. This super isolated spot is home to a graveyard filled not with human remains, but hundreds of broken up spacecraft and satellites. And after more...

EMPs aren’t science fiction. Real militaries are experimenting on real EMP generators, and as Starfish Prime showed us, space nukes can send powerful EMPs to the surface. So what exactly is an EMP, and how dangerous are they?

In 1995, a few years after the collapse of the Soviet Union, a top-secret, first-of-its-kind US spy satellite program was declassified, leading to the unexpected story of how former enemies would become scientific allies, and technology...

We know pollution is a problem on earth, but we’re filling space with our junk too. And if we don’t figure out a way to clean up space junk, we could end our interstellar dreams before they even get started. Today, we’re visiting some...

If gravity is so attractive, why doesn't the earth just crash into the sun? Or the moon into the earth? The answer: Stable Orbits

You might be pretty confident that when a moon is there it’s there to stay, but that’s not always the case. Moons may have a history of disappearing.

Right now, invisible signals are flying through the air all around you. Massive radio waves carry information between computers, GPS systems, cell phones, and more. And the sky is flooded with interference from routers, satellites, and,...

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.

Why NASA Uses Satellites and Airplanes to Study Frogs

Good weather forecasts save lives, but scientists are worried that 5G transmissions could drown out frequencies measured by weather satellites, setting weather forecasts back decades.

Most of us are hoping that any nuclear threats are just empty threats, and getting at the facts about ICBMs can be difficult. But what would actually happen if someone launched a nuclear weapon?

Earth’s magnetic field is special! And, in the last 20 years, we’ve made incredible discoveries, thanks to a squad of probes that have flown around our planet, observing solar wind as a team!

This week we’re exploring aerospace engineering and its two main fields: aeronautical engineering and astronautical engineering. We’ll explore life & buoyancy, propulsion systems, and the challenges of managing the human body in space.

Sometimes, ancient ruins can be a little out of the way, but with some creativity, we can use satellites for those hard to reach areas.

There’s a big difference between the number of satellites that simulations predict, and the number we’ve actually seen with telescopes, but why?

Danielle Wood leads the Space Enabled research group at the MIT Media Lab, where she works to tear down the barriers that limit the benefits of space exploration to only the few, the rich or the elite. She identifies six technologies...

Building and launching rockets to learn about other worlds hasn't been great for Earth, but environmental engineers are working on changing that legacy.

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.

We're in the dawn of a new space revolution, says engineer Peter Beck: the revolution of the small. In a talk packed with insights into the state of the space industry, Beck shares his work building rockets capable of delivering small...

Where did astronomers finally conclude that the 'Weird! Signal' was coming from? What has Elon Musk been up to with SpaceX and the Falcon Heavy rocket?

Imagine being excited to use one of the world's most advanced telescopes, only to see bright streaks of light on every picture! This is a problem facing some astronomers as satellites fill up the night sky.

The universe gets a little weirder, and more dangerous, every time we study it. Understanding space weather, which can mess with our communications systems, will take strategic planning to monitor.

Today we're going to talk about SPAAAAAACE, but not like stars and satellites and stuff. Instead, we're going to talk about geographic space. In geography, we can look at the world and the places and spaces we inhabit with four distinct...
