Why is the Sky Any Color?
Adults Science WorldIt's a question that you'd think kids have been asking for thousands of years, but it might not be that old at all. The ancient Greek poet Homer never used a word for blue in The Odyssey or The Iliad, because blue is one of the last colors that cultures pick out a word for.
The Science and Beauty of Auroras
Adults Science WorldSpace might seem like an empty place, but the area surrounding Earth is constantly being bombarded by waves of charged particles released by the Sun: The solar wind. Luckily, thanks to Earth's swirling, molten core (and the magnetic field it provides), we are protected from this planet-sterilizing onslaught like an invisible force field.

Preparing for #CometLanding
Adults Science Space TechnologyAfter a ten-year journey, Rosetta and Philae had finally reached their destination, Comet 67P/Churyumov-Gerasimenko. Rosetta spent many weeks studying the comet, sending lots of information back to Earth. But where was Philae going to land? Eventually the scientists on Earth found the best place on the comet for Philae to land. Soon it was time to make the final preparations for Philae's great adventure. Both spacecraft couldn't wait any longer. The whole world would be watching as Rosetta and Philae prepared for their biggest challenge yet.
The language of lying
Adults Language SocietyWe hear anywhere from 10 to 200 lies a day. And although we've spent much of our history coming up with ways to detect these lies by tracking physiological changes in their tellers, these methods have proved unreliable. Is there a more direct approach? Noah Zandan uses some famous examples of lying to illustrate how we might use communications science to analyze the lies themselves.
Astronauts Grow a Water Bubble in Space
Adults Gadgets Physics SpaceDuring Expedition 40 in the summer of 2014, NASA astronauts Steve Swanson and Reid Wiseman - along with European Space Agency astronaut Alexander Gerst - explored the phenomenon of water surface tension in microgravity on the International Space Station. The crew "submerged" a sealed GoPro camera into a floating ball of water the size of a softball and recorded the activity with a 3-D camera.
Life by the Numbers
Adults Animals Biology NatureThere are now more than 7 billion human beings on Earth, and that got me wondering: How successful are we compared to other species? I take a look at out how our numbers stack up to some other domains of life. It turns out that biomass, or what things weigh, can be more important than how many of something there are. Find out how our numbers stack up against everything from bugs to bacteria, and get ready for some mind-blowing numbers!
