Top] [Prev] [Next] . The Kepler mission will observe ~120,000 stars to detect 0.01% drops in brightness due to transits of Earth-sized planets, which must be recognized against intrinsic stellar variability, detector and photon noise. We examined a backside-illuminated CCD under Kepler-like conditions, and obtained a total precision of 1.3?10-5 at a flux of 1010 e-, indicating a detector error of 7?10-6. ...

... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth. During a recent investigation by an international group of astronomers [1], the best picture ever of Pluto and Charon [2] was secured with the European Space Agency's Faint Object Camera at the Hubble Space Telescope (HST). ... The new HST image was taken when Charon was near its maximum elongation from Pluto (0.9 arcseconds). ...
