Kepler's Transit Trick Helps Discover Alien Worlds | Video
More space news and info at: http://www.coconutsciencelab.com - the Kepler Space Telescope works by detecting brightness changes in stars, often caused by transiting exoplanets.
The spacecraft does not produce images or even colorful spectrograms, but rather light curves derived from brightness changes collected from these transits.
Please rate and comment, thanks!
