It was our pleasure to welcome Prof. Didier Queloz for our first annual Habitability GRP keynote lecture. Prof. Queloz shared the 2019 Nobel Prize in Physics with Michel Mayor and James Peebles, for discovering the first exoplanet orbiting a Sun-like star, 51 Pegasi b. We were treated to a fascinating overview of past, present and future efforts to find life on worlds outside the Solar System. Upcoming missions like JWST and PLATO will probe more effectively than ever before, edging us ever-closer to answering the age-old question: are we alone?
