Euclid is a space mission whose primary purpose is to study the cosmology of the universe. This will be accomplished by obtaining deep visual and near-infrared imaging, as well as spectroscopy, of distant galaxies. The resolution in the optical will be of Hubble quality, but over 15,000 deg^2 in the wide survey down to 24.5 mag, and 40 deg^2 deep fields down to 26.5 mag. The UK has a significant presence within this survey in terms of measuring cosmological features, but it is not well known within the UK community of the vast amount of non-cosmological science that can be done with the acquired data. Euclid will have a substantial legacy value for the study of galaxies, galaxy clusters, stars, supernova and other variable sources, and extrasolar planets. Euclid will also be a valuable resource when combined with other data such as SKA and LSST. The UK is a full member of the Euclid project, and it is possible for any astronomers to get involved and contribute. This session's purpose is to allow astronomers working on Euclid to give updates on the survey, and for those interested, to find out how to get involved in the science preparation.
