Centre for Space Exochemistry Data - CSED



The Centre for Space Exochemistry Data is involved in a number of projects across exoplanet science and astrochemical research, including the involvement in the ARIEL and Twinkle Satellite Space Missions.

ARIEL Space Mission

ARIEL (Atmospheric Remote-sensing Exoplanet Large-survey) has been selected as the fourth medium-class mission in ESA’s Cosmic Vision programme, due for launch in 2028.

Twinkle Space Mission

Twinkle is a small satellite designed to analyse the atmospheres of planets orbiting distant stars, as well as objects in our own Solar System. Twinkle is managed by Blue Skies Space Ltd.

The ExoAI project is funded by the European Research Council to explore the use of machine learning and deep learning to the data analysis and interpretation of exoplanetary data.


The ExoMol project aims to produce high temperature line lists of spectroscopic transitions for key molecular species likely to be significant in the analysis of the atmospheres of extrasolar planets and cool stars. This molecular data is crucial foraccurate astrophysics models of the opacity and spectroscopy of these atmospheres.


The ExoLights project is funded by the European Research Council to develop novel techniques for data analysis and interpretation of exoplanet atmospheres as well as new space mission concepts for exoplanet spectroscopy.
