9. http://www.eso.org/public/news/eso1227/kids/
... Astronomers have used a new technique to see the faint light from a planet that is orbiting a distant star. ... Instead, astronomers found them by looking for telltale clues, such as how the light from a star dims when an exo-planet passes in front of it, or how it wobbles because of the pull of an exo-planet s gravity. Astronomers can learn a lot about exo-planets that move in front of their stars. This is because the starlight passes through the exo-planet s atmosphere on its way to Earth. ...
