Using Color to Search for Alien Earths

Date- 25th Oct 10 Source- http://www.nasa.gov/centers/goddard/home/index.html 'NASA scientists grouped the planets of our solar system according to the amounts of red, blue and green light they reflect. When plotted, the planets fall into distinct regions that indicate surface or atmospheric properties. Earth's color and position on the plot is unique. The method works even when the planet is a point source, so astronomers can use it to find earthlike worlds.'
