The Kepler Mission discovered a new earth-like extrasolar planet.

European scientists recently used a telescope instrument called HARPS to measure the chemical content of 500 stars similar to the Sun, some with known planetary systems and others without.

NASA scientists have announced that they’ve detected carbon dioxide on a planet 63 light-years from Earth. The new find is another technical triumph, part of a growing effort to measure the chemical makeup of faraway worlds.

At long last, two teams of scientists have directly glimpsed the feeble light of planets orbiting distant stars through the lenses of telescopes.
