Using Color to Identify Planets | NASA Planetary Sciences

Discover how scientists compare the reflected red, blue, and green light from planets in our solar system to identify Earthlike planets beyond our solar system more easily. Carolyn Crow, a member of the Deep Impact science team, describes how the amount of green, blue, and red light reflected by planets can be plotted. A diagram compares the color data of the planets and shows that Earth is easily distinguishable by its blue color. Although it will be some time before telescopes can really show what extrasolar planets look like, scientists will be able to identify which planet an exoplanet most resembles by measuring its color.

ScienceCasts: A Good Year for Perseid Meteors

This week, Earth passes through a stream of debris from Comet Swift-Tuttle, source of the annual Perseid meteor shower. Forecasters say the show could be especially good this year because the Moon is nearly new when the shower peaks on Aug. 12-13. Visit http://science.nasa.gov/ for more. Click her
