Many agencies, organisations and companies have contributed to the development of Euclid. This map highlights the main contributing ESA Member States and funding agencies.
The National Aeronautics and Space Administration (NASA) of the United States has also contributed to the project by providing the detectors of the Near-Infrared Spectrometer and Photometer (NISP).
Scientists from more than 300 institutes are part of the Euclid Collaboration and will participate in the scientific harvest of the mission.
Euclid is ESA’s space telescope designed to explore the dark Universe. The mission will create the largest, most accurate 3D map of the Universe ever produced across 10 billion years of cosmic time. Euclid will explore how the Universe has expanded and how large-scale structure is distributed across space and time, revealing more about the role of gravity and the nature of dark energy and dark matter.
