Join us as we explore how the Copernicus Sentinel satellites detect gases such as nitrogen dioxide, and how chemistry helps us understand what’s happening in the atmosphere above us.
Claudia Mignone and Rebecca Barnes take us on a tour through the electromagnetic spectrum and introduce us to the European Space Agency’s fleet of science missions, which are opening our eyes to a mysterious and hidden Universe.
