Sometimes the most advanced forms of technology are also the simplest. The LightSail 2, a satellite conceived by Bill Nye's non-profit Planetary Society, has proven that a satellite can orbit the Earth fueled completely by the sun. The concept, dreamed up 400 years ago by Johannes Kepler, has finally become a reality.

The LightSail 2 doesn't run on solar panels but instead solar sailing – an entirely different concept. It's kind of like a sailboat, but instead of using wind to make it move, it's powered by photon particles from the sun that bounce off of a sail made from a large reflective surface. The photon particles give it a "tiny push no stronger than the weight of a paperclip," Nye told CNN.

Bill Nye is a very sad Science Guy.

Our climate is changing, and the planet is in danger. The science that lends Bill Nye his nickname — the thing he's dedicated his life to — is the only thing that can save us.

Unfortunately, there's a small but incredibly vocal minority who refuse to yield to facts — and whose stubborn resistance has already done massive damage to the planet we call home.
