| Abstract | The Euclid Data Release 1 (DR1) is an initiative of ESA and the Euclid Consortium. The core content of Euclid DR1 includes wide survey observations for a total sky coverage of about 1900 deg2. Roughly 500 deg2 are observations taken in the Northern hemisphere and 1400 deg2 are taken in the Southern hemisphere. In addition to the wide survey, DR1 also includes data from the Euclid deep fields, the calibration fields, as well as observations taken before the start of the nominal survey. |
| Description | An overview of the Euclid DR1 content can be found here: https://www.cosmos.esa.int/web/euclid/euclid-dr1 |
| Publication | https://www.cosmos.esa.int/web/euclid/dr1-papers |
| Temporal Coverage | Euclid DR1 includes valid and complete data acquired from the start of the wide survey, on 14th February 2024, until the 21st May 2025. |
| Mission Description | Euclid is an ESA science mission that was launched on the 1st of July 2023 to survey one third of the extragalactic sky with the aim to investigate the origin of the accelerating expansion of the Universe and the nature of dark energy, dark matter and gravity. Euclid will map the geometry of the Universe, and reconstruct the evolution of large-scale sctructures over the past 10 billion years. |
