- Description
Corot will be the first mission capable of detecting rocky planets, several times larger than Earth, around nearby stars (planets outside our Solar System are referred to as ëexoplanetsí). It consists of a 30-centimetre space telescope and will be launched later in 2006.
Corot will use its telescope to monitor closely the changes in a starís brightness that comes from a planet crossing in front of it. While it is looking at a star, Corot will also be able to detect ëstarquakesí that send ripples across a starís surface, altering its brightness. The exact nature of the ripples allows astronomers to calculate the star's precise mass, age and chemical composition. From the ground, the only planets detected around other stars have been giant gaseous worlds (Jupiter-like planets), over 10 times the diameter of the Earth. Not affected by the distorting effects of the atmosphere, Corot will be the first spacecraft capable of finding worlds made of rocks. With Corot, astronomers expect to find between 10-40 of them,Title : ""COROT, in search of other worlds"" .

Understanding how stars live and die, and detecting planets around them has progressed enormously in recent years. But much more is to come.
France's upcoming 'COROT' mission promises to be a world premiere, detecting distant stellar phenomena and objects which have never been studied before.
00:00:59 For ten years now, SOHO has been listening to the melodious vibrations of our Sun, ""star-quakes"" that send ripples across its surface, providing information on its internal composition.
00:01:10 COROT ñ standing for 'Convection Rotation and planetary Transits' ñ has been designed to observe these periodic oscillations in other stars of our Galaxy.
