SUMMARY
Euclid is a space telescope for observing the acceleration of the Universe to better understand dark energy and dark matter. Data will be collected in the darkest area of the sky, free of contamination by light from our Galaxy and our Solar System. Euclid will observe about ten billions of light sources. The complete survey represents hundreds of thousands of images and several tens of Petabytes of data. The big data challenge will consist of efficiently managing and processing the vast amount of data in a distributed ground segment architecture with ten data centres distributed around the world. Furthermore, machine learning techniques play an important role to automatically extract relevant information from the image data for the scientific analysis.
