A bunch of lunar volcanoes heated the Moon up so much, they changed its density, causing it to wander off its original axis aeons ago.
In 1964, the last time Tokyo hosted the Summer Olympics, the nation revealed one of the biggest mic drops in transportation history: the debut of the shinkansen, the world-famous bullet train that became a Japanese icon. The first high-speed train in the world, it spurred similar technology to spread to Europe and…
Hydrogen fuel cells are a cool technology that were perfected to enable humans to go to the moon. Now that they're perfected even more, they're enabling humans to go to work or the liquor store, and, incredibly, this is progress. The Toyota Mirai is an example of this remarkable progress. Funny looking, maybe, but it…
We think we got the first hydrogen-based airship disaster caught on tape. In fact, the first horrific explosion of an airship came over a century before the Hindenburg, and it combined a military test ship disaster with a tragic love story.
Hydrogen can be devastating, but in the right hands, it can also be awesome. When burned, for instance, it emits only water vapor instead of nasty carbon dioxide that's responsible for much of the climate change we see today. Now, researchers have discovered a way to convert methane — the same gas that makes landfills…
Making explosive gas is a basic skill, and doing it can teach you a lot about chemistry. What you use that gas for is up to you. But please be careful.
What's the difference between a hydrogen explosion and an oxygen explosion? Quite a lot. Take a look at this succession of exploded balloons, and compare the booms.
An astronomer from West Virginia University has discovered a never-before-seen river of hydrogen flowing through space—and it could explain why spiral galaxies keep up their pace of star formation.
People have been talking about running cars on water for years, but it's a slow march from science fiction to reality. Even on a small scale, development is difficult. But the i-H2GO is the second revision of an all-water remote controlled car that seems to actually work.
Fuel-cell-powered vehicles are still a long ways off. But fuel cell-powered toys? That's an awesome reality that's about to get even better with Horizon Fuel Cell Technologies new H-Rover, which includes a wireless camera streaming live video to your smartphone/remote.
Chinese researchers have turned to the light absorbing properties of butterfly wings to significantly increase the efficiency of solar hydrogen cells, using biomimetics to copy the nanostructure that allows for incredible light and heat absorption.
At first glance, there doesn't seem to be anything particularly remarkable about star HIP 11952 and its two planets. But its iron-poor composition reveals these planets are 13 billion years old — almost as ancient as the Big Bang itself.
It's fun to watch chemistry labs explode on video, but you know what's even more fun? Watching a chemistry experiment in action, with a good explanation of what's going on. That's science at its most awesome. Here are ten of our favorite chemical reactions caught on video — which also include excellent commentary on…
Humans produce two flammable gases: hydrogen and methane. Flammable gases accumulate in an enclosed space and can ignite. Astronauts are humans who spend lots of time in enclosed space. The logic is irrefutable. So, what's the risk to farting astronauts?
Located some 11 billion light-years from Earth are two clouds of gas. Just two billion years younger than the Big Bang itself, they appear to be the first known clouds that are completely unaltered since the birth of the universe.
Hydrogen is the most abundant element in the universe, but it's not all that useful as a gas. Two scientists say they've coaxed it to become a metal, which could be used in ways that would radically change our lives.
