ESA Science & Technology - Euclid
Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures 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. In this way, Euclid will cover the entire period over which dark energy played a significant role in accelerating the expansion.
23 July 2019A major step towards the completion of the scientific payload on ESA's Euclid space mission has been completed, following the delivery of the detectors for the Near Infrared Spectrometer and Photometer (NISP) instrument.
12 June 2019Scientists in the Euclid Consortium have selected three extremely dark patches of the sky that will be the subject of the mission's deepest observations, aiming at exploring faint and rare objects in the Universe. The position of the Euclid Deep Fields – one in the northern sky and two in the southern sky – was announced last week, during the...
18 December 2018ESA's Euclid mission has passed its critical design review, marking the successful completion of a major phase in the progress of the project.
15 November 2018In order to observe billions of faint galaxies and investigate the nature of the dark Universe, ESA's pioneering Euclid mission will require state-of-the-art optics. The first optical element to be delivered, the telescope's primary mirror (M1), has arrived at the premises of Airbus Defence & Space in Toulouse.

Scientists of the Euclid Consortium announce the release of the largest simulated galaxy catalogue ever built
7 June 2017Euclid will map the geometry of the dark Universe by observing thousands of millions of galaxies. To prepare for the scientific exploitation of the real data, a team of scientists of the Euclid project have developed the largest ever simulated galaxy catalogue: the "Euclid Flagship" mock galaxy catalogue.
22 January 2010The Euclid Mission Assessment Study is the industrial part of the Euclid assessment phase. This document summarizes the results of one such study performed between September 2008 and September 2009 by a team led by Thales Alenia Space (I) and including Thales Alenia Space (F), Kayser-Threde and Deimos Space.
22 January 2010The Euclid Mission Assessment Study is the industrial part of the Euclid assessment phase. The study has been performed by Astrium from September 2008 to September 2009 and is intended for space segment definition and programmatic evaluation. The prime responsibility is with Astrium GmbH (Friedrichshafen, Germany) with support from Astrium SAS...
