Euclid wide-angle space telescope

ESA’s Euclid mission is designed to explore the composition and evolution of the dark Universe. The space telescope will create a great map of the large-scale structure of the Universe across space and time by observing billions of galaxies out to 10 billion light-years, across more than a third of the sky. Euclid will explore how the Universe has expanded and how structure has formed over cosmic history, revealing more about the role of gravity and the nature of dark energy and dark matter.

The Euclid telescope is a European Space Agency (ESA) mission launched on July 1, 2023, to study the dark universe by mapping the large-scale structure of the cosmos. It uses its wide-angle camera and instruments to observe billions of galaxies across a third of the sky, helping astronomers understand the roles of dark energy and dark matter in the universe’s evolution and expansion. It was launched on a SpaceX Falcon 9 rocket and orbits at the Sun-Earth Lagrange point 2.
