Call it the deep blue dot. For the first time, scientists have seen the visible color of a distant alien world. The exoplanet — called HD 189733b — is a "deep cobalt blue," orbiting its star 63 light-years from Earth, scientists say.

Some people may be disappointed that NASA's next Mars rover won't carry a life-detection experiment, but hunting for currently existing Red Planet microbes is decidedly premature at this point, mission planners say. Looking for past life is a better bet.

NASA's next Mars rover, slated to launch in 2020, should hunt for signs of past Red Planet life and collect samples for eventual return to Earth, a team of mission planners has determined. The robot should explore a site that once was habitable, make its
