ESA’s Euclid mission is designed to uncover the properties and effects of the elusive dark matter and dark energy, entities believed to be dominating the universe’s composition but remain undetected directly. Euclid will create a 3D map of the Universe, utilizing time as its third dimension, by observing billions of galaxies up to 10 billion light-years away. This extensive mapping will help scientists chart the position and velocity of galaxies across vast distances and through cosmic history, shedding light on the Universe’s expansion over time.

The primary goal of the Euclid mission is better understanding of the nature of dark energy and dark matter, two of the greatest mysteries of modern physics. The mission aims to do this by surveying galaxies in the universe, leveraging a 1.2-meter diameter telescope and two instruments to capture visible and near-infrared imagery.
The Euclid mission will attempt to map the geometry of the dark Universe by investigating the distance-redshift relationship and the evolution of cosmic structures. This will be achieved by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a look-back time of 10 billion years. Through this, the mission hopes to better understand the accelerating expansion of the Universe, which is currently attributed to a mysterious dark energy.
