Seven Earth-sized planets discovered orbiting a neighbour star
This discovery has raised hopes of finding alien life beyond our solar system much sooner than previously expected, with a new generation of telescopes expected for the next decade. It is the very first time that so many Earth-sized planets (seven) have been found orbiting around the same star. A part from the size, other conditions, such as distance to the sun or the fact that we are dealing with rocky planets, resemble our own home. Illustration: NASA/JPL-Caltech
