NASA has launched its new Kepler spacecraft, marking the beginning of a three-and-a-half year hunt for planets in distant solar systems of a similar size to the Earth. Every hour Kepler will record the brightness of some 100,000 stars and will concentrate on the 'Goldilocks region' of space where scientists believe the conditions are just right for liquid water to exist.
The launch of the Kepler spacecraft from Cape Canaveral in Florida today marks the beginning of the most ambitious hunt for planets like ours in distant solar systems. The Kepler telescope will spend three-and-a-half years staring deep into a starry region of the Milky Way, in the direction of the constellations Cygnus and Lyra, in the hope of spotting Earth-sized planets as they pass in front of their stars."
