It was only 25 years ago that the first exoplanet (a planet orbiting a star outside of our Solar System) was detected! This discovery was recently recognized with the Nobel prize. Now we know more than 4500 exoplanets, and their study has become one of the most dynamic and fascinating research fields in astronomy.
Two ESA experts provide insight into the design and development of CHEOPS — the first mission of the European Space Agency dedicated to the characterization of known exoplanets, which is already in orbit.
