Sometimes, in order to learn something, you've got to punch a giant asteroid.

Mars Express, one of the longest-running planetary probes ever made, was only intended to last for about two Earth years, but it's still going at 17! And it's taught us an unbelievable amount, including everything from studying its...

From what we know about Titan, it seems like its atmosphere should have disappeared millions of years ago. So, why hasn’t it?

If you think punching an asteroid to knock it off the course to Earth’s destruction is purely for science fiction, you might only be right a for a little longer! Plus, scientists are being thrown for a loop with the orbits of planets...

Tuna are ocean athletes -- fast, far-ranging predators whose habits we're just beginning to understand. Marine biologist Barbara Block fits tuna with tracking tags (complete with transponders) that record unprecedented amounts of data...

For the past 90 years, the predictions laid out Einstein's general theory of relativity have continued to be confirmed by experimental science. The last hold out is gravitational waves - the idea that certain gravitational events cause...

Rovers like Curiosity search for life on Mars using rock and soil samples, but why don't they examine liquid or frozen water?

SciShow Space takes you through perhaps the scariest part of every space mission -- re-entry. How do astronauts survive the turbulent return to Earth’s atmosphere? Math, y’all!

A paper published last week proposed a hypothesis that identified 95% of the missing stuff in the universe, but the headlines have been a little over-hyped.

Filmmaker David Hoffman shares footage from his feature-length documentary Sputnik Mania, which shows how the Soviet Union's launch of Sputnik in 1957 led to both the space race and the arms race -- and jump-started science and math...

John Hunter puts all the problems of the world on a 4'x5' plywood board -- and lets his 4th-graders solve them. At TED2011, he explains how his World Peace Game engages schoolkids, and why the complex lessons it teaches -- spontaneous,...

NASA recently sponsored new research into turning human waste into useful things, like food and plastic. And it might be used on long-term spaceflight someday.

We think of space as a silent place. But physicist Janna Levin says the universe has a soundtrack -- a sonic composition that records some of the most dramatic events in outer space. (Black holes, for instance, bang on spacetime like a...

Cave diver Jill Heinerth explores the hidden underground waterways coursing through our planet. Working with biologists, climatologists and archaeologists, Heinerth unravels the mysteries of the life-forms that inhabit some of the...

Earth's thick crust might one of the reasons our planet can support life. But scientists are looking for something a little more brittle.

Scientists picked up two unusual signals that seemed to be coming up from the ground instead of down from space. They're still working on understanding why, but despite what you may have heard, they aren't evidence for a parallel...
