Current plans for flagship telescopes in the 2040s are focused on answering a simple question - are we alone? Our best telescopes to date, such as the James Webb Space Telescope (JWST) have only given us tantalizing glimpses into the atmospheres or other worlds, but not enough to truly determine whether or not life as we know it exists there. Astronomers have been waiting for technology to catch up to their dreams of what is possible in terms of new types of telescopes, and recently the W.M. Keck Institute for Space Studies released a report detailing the Large Interferometer For Exoplanets (LIFE) mission, which they hope will help provide a definitive answer to that simple question.

Meet the voices astronauts hear in space. At ESA’s European Astronaut Centre in Cologne, Germany, the EUROCOM team is the link between crew and ground, guiding astronauts like ESA astronaut Sophie Adenot through their daily work on the International Space Station. Join us as EUROCOM expert Andreas Orth explains how complex operations are translated into clear, real-time communication and what it means to be the one voice connecting Earth and orbit.
