Led by the European Space Agency (ESA), the Euclid satellite will transform our knowledge of the Universe. During the six years of its nominal mission, Euclid will photometrically and spectroscopically survey one third of the sky (~14000 deg2) in order to shed light on the nature of dark energy and dark matter. Using its two primary probes - weak gravitational lensing and galaxy clustering - Euclid will be able to map the dark matter distribution of the Universe to unprecedented precision and constrain the dark energy equation of state. In addition, the depth and resolution of the Euclid instruments will enable a plethora of studies for legacy science for decades to come.

ESA and the Euclid Consortium have put a lot of effort into the first Quick Release (Q1), comprising approximately 50 square degrees that will be made available to the scientific community in spring 2025. We wish to use this Special Session to describe the properties of this state-of-the-art dataset to maximise its scientific return within the broader community. We will also highlight some of the most exciting scientific results that have emerged from analysing this dataset within the Euclid Consortium, all of which constitute an important stepping stone towards for the first full Data Release (DR1), expected in the coming year.
