Out there - The quest for extrasolar worlds For thousands of years, mankind thought that the Earth was the centre of the Universe. Thanks to our curiosity, imagination and urge to explore, we now k now that planets like our Earth are nothing special in the cosmos. The Sun is just one ordinary star among hundreds of billions in our galaxy, the Milky Way. With the world’s most powerful telescope s, we are able to explore more and more of the Universe. What we have found so far has surpassed even the wildest expectations of scientists as well as authors of science fiction. Most stars have plan ets — it turns out they are more common than we thought. A huge diversity of different worlds is out there, just waiting to be discovered.
