In this undated illustration provided by the European Space Agency (ESA), an artists impression of one of Earth's nearest planets outside the solar system named HD 189733B. Astronomers said Friday, July 12, 2013 that for the first time they had gained an understanding of HD 189733B, which is around 63 light years away by discovering the huge gas giant’s blue color. To ascertain the planet’s color the astronomers measured the amount of light reflected of its surface as it eclipsed its host star. (AP Photo/ESA-Hubble, M. Kornmesser) less
