How Long Can You Live Underwater?
In 2023, Joseph Dituri set a world record for the longest continuous stay underwater. And that 100 day stay had effects on both his body and mind. Scientists have been studying the effects of living underwater since the 1960s, but how...

We Finally Found a Green Use for Coal
One day, the world may partially run on clean hydrogen fuel. But a big barrier to that future is just how darn difficult it is to store hydrogen for later use. So one team of scientists have proposed making hydrogen "batteries" out of...

The Asteroid That Nearly Swallowed OSIRIS-Rex
It's always an asteroid heading straight toward us that we worry about, never what happens to us when we head straight toward the asteroid. OSIRIS-REx's experience with Bennu tells us it's worth a thought.

New and Ancient Lessons from Lunar Eclipses
Ancient perceptions of lunar eclipses weren’t as primitive as one might think. Some rigorous math was applied to these cosmic events that shaped our understanding of the solar system.

What Will It Be Like To Live on the Moon? | Compilation
The Moon is pretty prime real estate once you get past the lack of oxygen, resources, and general mobility, but if quality of life isn't what you're after, here's how we might make it all work.

The One-Second Success Story of Venera 7
Venus may have been named after the Roman goddess of beauty, but once humans started sending spacecraft to the planet next door, we quickly learned that beauty… hurts.

The Future of the Search for Life
Astronomers have found more than 5,000 planets in the last three decades, but that’s not nearly as exciting as potentially coming across the first extraterrestrial creatures. And we may finally be in a position to make that discovery.

Hayabusa: The Artificial Meteor Launched From An Asteroid
After we retrieved samples of the moon, it was quite a while before we could land on anything else and bring bits of it back home.

The Ominous Reason Phobos Has Lines on It
Mars’s moon, Phobos, is striped with grooves all across its surface. But if one theory about where they came from is true, does that mean this moon might be on its way out?

Where Did Mercury’s Spots Come From?
The Sun isn’t the only celestial body in the solar system to boast spots of its own. Mercury, too, has its fair share, and they’re worth wondering about.

The Spacecraft That Wasn't Designed To Land, But Did
Many space missions take billions of dollars and decades of work to get develop, but 25 years ago this spacecraft delivered stunning results on a shoestring budget and a minimal development timeline.

The Rocket that Hopped
Surveyor 6 may not have been the first craft to make a soft landing on the Moon, but it is the first craft to take off from the surface of another world. And it did so in a very adorable way. Long before any Apollo astronaut, Surveyor 6...

This Planet is Only Half Covered in Lava
There are a lot of weird exoplanets out there, like 55 Cancri e (aka Janssen), which is probably half covered in lava. But the half that's covered in lava might not be quite the half you're thinking of.

How Blocking the Sun Makes Mars Hotter
If we’re going to send people to Mars someday, we’re going to need to be very conscious of the challenges presented in this endeavor. And at the top of that list is the ferocious nature of dust on the barren planet.

Could We Terraform Mars?
We already have the technology to bring humans safely to Mars and set up small settlements - or at least could do within a generation. But those settlements will need to be cocooned - shielded against the deadly cold, intense radiation,...

Building Black Holes in a Lab
Black holes are about the worst subjects for direct study in the universe. But at this stage, it’s all we can do to convince ourselves of their existence. Actually studying the physics of real black holes is much, much harder. I mean, we...

The Boundary Between Black Holes & Neutron Stars
When we detected the very first gravitational wave, a new window was opened to the mysteries of the universe. We knew we’d see things previously thought impossible. And we just did - an object on the boundary between neutron stars and...
