Euclid’s goal is to produce scientific insight in the fields of cosmology and astrophysics. New knowledge comes in the shape of understanding of processes, new ‘laws of nature’, or numbers relating different physical properties to each other. However, the Euclid spacecraft initially observes the sky, and its data after a downlink to Earth is processed in a set of complex data analysis pipelines to extract such numbers and relations. Some of the images that have been calibrated to scientific standards that allow such an extraction have already been publicized – but how does Euclid’s raw, unprocessed view into the sky look?

Euclid has been surveying the sky since 14 February 2024 and data processing is in full swing – the first public release of 53 deg² of science-grade Wide Survey data will take place in March next year. But how much data has Euclid already observed and how can we possibly visualize this? At a rate of 10 deg² per day, the Euclid Wide Survey has already surpassed 1000 deg², that is 5000x the apparent size of the Moon in the sky! Now ESA has put out a first set of images that allow to grasp how much data Euclid is and will be producing.
