The Euclid telescope should enable us to learn more about dark energy and dark matter in the Universe. These two components account for 95% of the content of the cosmos, but we still know nothing about their nature.© ESA/Euclid/Euclid Consortium/NASA. Background galaxies: NASA, ESA, and S.

Euclid: a satellite to explore the dark Universe

Astroparticles and cosmology

The Universe still conceals so many mysteries! Among them, two stand out: dark energy and dark matter. What is their nature? How do they influence the very destiny of the cosmos? These tenacious questions deserve extraordinary resources. That's why the European Space Agency's (ESA) Euclid space telescope was designed. Its mission: to probe the dark Universe! IN2P3 is at the heart of the action, participating in the construction of the NISP instrument and managing and exploiting the huge amount of new data that the satellite will produce.
