- The Euclid mission is a space telescope being developed by the European Space Agency (ESA) to study the dark universe, including dark matter and dark energy.
- Euclid will map the distribution of galaxies over a large portion of the observable universe, allowing scientists to better understand the nature of dark energy and the evolution of the cosmos.
- The mission is expected to provide insights into the fundamental physics behind the accelerated expansion of the universe, which is currently one of the biggest mysteries in cosmology.
