Scientists confirm 'dry ice' snowfall on Mars

In 2008, we learned from the Phoenix Mars lander that it snows in the Martian north polar region — perhaps quite regularly — from clouds made of water vapor. But now, Mars Reconnaissance Orbiter data has revealed the clearest evidence yet of carbon-dioxide snowfalls on Mars. Scientists say this is the only known… » 9/12/12 11:20am 9/12/12 11:20am

Ten amazing (and occasionally explosive) chemical reactions, caught on…

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… » 2/20/12 10:53am 2/20/12 10:53am

The Beautiful and Bizarre Dry Ice Pits of Mars

All around the Martian south pole, there are huge deposits of frozen carbon dioxide, better known as dry ice. In this image by NASA's Mars Reconaissance Orbiter, we can see huge dry ice pits... and the mysterious walls that encircle them. » 9/26/11 7:30am 9/26/11 7:30am
