Earth-Like Planets Found With New Tool, Researchers Count 10 Exoplanets

We may not have found life on other planets yet, but it turns out we might find another planet like Earth. There seems to be a "recipe" to create an Earth, suggests a study by the Harvard-Smithsonian Center for Astrophysics. Astronomers were able to see exoplanets, those planets orbiting a star other than the sun, using a new tool, the HARPS-North instrument on the 3.6-meter Telescopio Nazionale Galileo, in Spain's Canary Islands.
