On the ground, numerous small and medium (up to 1 meter in diameter) sized telescopes exist, and are in the process of being set up, or are under consideration, with the aim of detecting "hot Jupiters" using the transit method.

In space, the CNES should launch a 30cm telescope called COROT in 2006, in collaboration with other European countries. As its name indicates (Convection, Rotation and planetary transits), this mission will study the rotation and the convection of several bright stars, and search planetary transits around 60000 stars (up to a magnitude of 16). The telescope is sufficiently sensitive to detect planets twice as large as the Earth (that is 20% of Jupiter's size).
