COROT

Sounding the Sun through a technique similar to seismology has opened a new era for understanding the Suns interior. The COROT satellite has now applied this technique to three stars, directly probing the interiors of stars beyond the Sun for the first time.
When global oscillations of the Sun were discovered, scientists realised they opened a window to the Suns interior. Like the propagation of seismic waves on Earth providing information about our planets interior, sound waves travel throughout the Sun carrying information about what is happening below the surface.
These oscillations can also be observed on other stars. They can be detected through the variation in the light emitted by the star as the surface wobbles the technique used by COROT. This reveals the internal structure of the star, and the way energy is transported from the core to the surface.

Well i think they have just found one rocky extrasolar planet, it is called Corot-7B. That was days ago, in came out on the news and u can search it. It is almost as big as Jupiter and it is like our moon to the earth, it always facing it sun in the same direction so it is really hot and the back side of the planet it very cold. I read that it is very closed to it sun witch i think it`s named Corot after the satellite.
