Colorful life-form catalog will help discern if we're alone
Ithaca NY (SPX) Mar 17, 2015
While looking for life on planets beyond our own solar system, a group of international scientists has created a colorful catalog containing reflection signatures of Earth life forms that might be found on planet surfaces throughout the cosmic hinterlands. The new database and research, published in the Proceedings of the National Academy of Sciences, gives humans a better chance to learn if we are not alone. "This database gives us the first glimpse at what diverse worlds out there could look lik ... read more
