Life beyond Earth? The best bet may be on moons, not planets

Science

The search is on for planets that could harbor life, but many of the candidates that we can see are more like gassy Jupiter than rocky Earth. But those planets may be home to rocky moons that can sustain life themselves

NASA’s Kepler mission has confirmed the discovery of a  planet in the habitable zone of a sun-like star. A NASA researcher says the Earth-like planet would have a surface temperature around 70 degrees Fahrenheit. This makes it a so-called “Goldilocks planet” –  not too hot, not too cold, just right to support life. Researchers have also measured […]
