Euclid

Euclid is a wide-angle space telescope with a 600-megapixel camera to record visible light, a near-infrared spectrometer, and photometer, to determine the redshift of detected galaxies. It was developed by the European Space Agency (ESA) and the Euclid Consortium and was launched on 1 July 2023 from Cape Canaveral in Florida. The mission is named after the ancient Greek mathematician Euclid. After approximately one month, it reached its destination, a halo orbit around the Sun-Earth second Lagrange point L2, at an average distance of 1.5 million kilometres beyond Earth's orbit. There the telescope is to remain operational for at least six years. The objective of the Euclid mission is to better understand dark energy and dark matter by accurately measuring the accelerating expansion of the universe. The Korsch-type telescope will measure the shapes of galaxies at varying distances from Earth and investigate the relationship between distance and redshift. Euclid is a medium-class ("M-class") mission and is part of the Cosmic Vision campaign of ESA's Science Programme. Euclid was chosen in October 2011 together with Solar Orbiter. Euclid was launched by a Falcon 9 rocket. On 7 November 2023 ESA revealed Euclid's first full-colour images of the cosmos, which illustrate Euclid's potential to create the most extensive 3D map of the universe. In May 2024, ESA's Euclid mission release
