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...

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...

How did life on Earth get started? Did life on Earth originate on another planet? Either Mars, or in a distant solar system? Could Earth life have spread to have seeded life elsewhere? Let's see what modern science has to say about the...

Space technology gets applied in all sorts of ways down here on Earth, making us more comfortable, healthier, and even saving lives!

There's an organism that changed the world. It caused the first mass extinction in Earth's history and also paved the way for complex life. How? Anusuya Willis explains how cyanobacteria, simple organisms that don't even have nuclei or...

The United Arab Emirates is planning an enormous colony on Mars, but first they are building the biggest Mars simulator right here on earth.

Is space the “final frontier” — or the perfect place to revolutionize life on Earth? Space architect Ariel Ekblaw reveals how self-assembling structures could build orbiting real estate in space dedicated to solving humanity’s greatest...

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...

If you think it's cold outside where you are, you should try living in the coldest place on Earth: Antarctica! Learn why it's a desert even though it's very cold, and about awesome animals like seals and penguins.

Astronomers have thought for years that Earth was dry in the beginning, but a new paper suggests that Earth might have actually started out wet! And In other meteorite news, a new study of impact sites might give us new clues about...

If we lived light years from Earth, how would we know there’s life here? Let’s take a look at the search for extraterrestrial life on habitable exoplanets, and discover what biosignatures would show someone else that we’re here.

From mice that battle scorpions to microscopic moss piglets that can survive a solar storm, here are 6 of Earth’s most hardcore beings!

From mice that battle scorpions to microscopic moss piglets that can survive a solar storm, here are 6 of Earth’s most hardcore beings!

From asteroids capable of destroying entire species to supernovae that could exterminate life on Earth, outer space has no shortage of forces that could wreak havoc on our planet. But there's something in space that is even more...

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...

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...

Angelique Van Ombergen details the unique experiments from the European Space Agency on the International Space Station. HWHAP Episode 217.

This Is The Only Meteorite That Has Landed On Earth Twice

There was a medical incident on the ISS which required NASA to treat an astronaut from Earth. And astronomers have discovered what might be some of the universe’s earliest stars.

Other worlds don't seem very welcoming to us Earthlings, and it can be hard to practice our off-world explorations from millions of kilometers away. But Earth also has its fair share of hostile places that we can use to prepare for those...

We’ve developed thousands of technologies for space exploration, but luckily for us, sometimes those solutions apply to problems here on the ground, too.

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?...

Lake Maracaibo is the stormiest place on the planet. Thunderstorms rage above this massive body of water for up to 200 days of the year, with each ear-splitting event lasting for several hours. But why? Graeme Anderson lists the factors...

International Space Station Program Chief Scientist Kirt Costello talks about some of the interesting new research underway in Earth’s orbiting laboratory right now, and shares results of earlier experiments that are already making a...
