The ExoMol group was part of the 2015 Origins of Life Exhibit at the Royal Society Summer Exhibition.
Over 10,000 people came to the exhibition, including school groups, families and adults of all ages. It was a collaboration between different groups at UCL, with ExoMol being a part of the Twinkle and Exoplanet atmosphere side. Visitors could look through a spectrograph at a model of an exoplanet system in order to understand how we find out what is in the atmospheres of these faraway worlds, amongst many other interactive activities.
