... And if we are no longer alone in the universe would be? The search for extrasolar planets and extraterrestrial life forms. The search for so-called exoplanets - planets orbiting around our sun is not, but to distant stars - is of paramount importance to you find an answer to one of the most probable most profound questions that mankind can ask: Are we alone in the universe? ESO's observatories are equipped with a unique arsenal of instruments that allow to find exoplanets and to study. With the VLT (Very Large Telescope) is the first time astronomers have failed to demonstrate the faint glow of a planet outside our solar system and so for the first time ever to depict an exoplanet. This new world is a giant planet, about five times as massive as Jupiter, the most massive planet in our solar system. This observation is an important step towards one of the main goals of modern astrophysics: to characterize the physical structure and chemical composition of giant planets and, ultimately, also from Earth-like planets. With HARPS, the High Accuracy Radial velocity Planet Searcher (literally, the "high-precision radial velocity planet hunter"), astronomers have discovered no less than three planets orbiting nearby stars and have similar masses as the planet Neptune. One of these planets has a mass about five times larger than Earth and is located in the habitable zone of its star. In this zone, temperatures prevail, in which water can exist in liquid form - the basic ...
