    Astronomers are on the hunt for more planets in other star systems In December, the Europeans launched a satellite called COROT to look some more. COROT, which stands for "Convection Rotation and Planetary Transits," is designed to detect the faint dimming of light as a planet moves between the observatory and its home star. COROT will also look for seismic waves that cause ripples on stars, giving hints to the stars' structures and perhaps their masses and ages.
