The race to discover the elusive "Earth 2.0" is on
Several research groups around the world are participating in this race. Our AstroCombs are an important part in the search for Earth-like planets. Therefor our Nobel Prize-winning optical frequency technology is being integrated in novel ways to develop state-of-the-art digital spectrographs with femtometer precision. The goal is to achieve the most precise measurements of stellar motion ever attempted.
