  With the immense number of images, data, and sources that Euclid will
deliver, the consortium will be in a unique position to
create/provide/construct legacy catalogues. The latter will have exquisite
imaging quality and good near-infrared spectroscopy, with impact on many areas
of galaxy science. These proceedings review the prospects and scientific output
that Euclid will be able to achieve in areas of galaxy and active galactic
nucleus (AGN) evolution, the local and primeval Universe, studies of the Milky
Way and stellar populations, supernovae (SN) and transients, Solar System
objects, exoplanets, strong lensing and galaxy clusters.
