Euclid Early Release Observations (ERO) Overview
Euclid ERO Overview ERO Image Data Access

Overview

The ERO programme is an initiative of the Euclid Science Team / ESA to collect 1 day of observations to showcase the Euclid mission and its capabilities before the start of the nominal survey. The ERO data products available at IRSA for the convenience of the US astronomy community are the same data products that are available through ESAC. The FITS files were processed with an ERO-specific pipeline, which is different from the standard Euclid pipeline that will be used for future data releases.

Data from the following projects are included in the release:
  • A first glance at free-floating baby Jupiters with Euclid - Lead scientist: E. Martin (Instituto de Astrofisica de Canarias) (Press Release, Press Release)
  • Euclid view of Milky Way globular clusters - Lead scientist: D. Massari (INAF-OAS Bologna) (Press Release)
  • A Euclid showcase of nearby galaxies - Lead Scientist: L. Hunt (INAF-AO Arcetri, Firenze) (Press Release, Press Release, Press Release)
  • A galaxy cluster seen with Euclid - Lead scientist: A. Lancon (Strasbourg Observatory) (Press Release)
  • A cluster of galaxies - Lead scientist: J.-C. Cuillandre (CEA, AIM, Universite Paris-Saclay) (Press Release)
  • A Glimpse Into Euclid's Universe Through a Giant Magnifying Lens - Lead scientist: H. Atek (Institut d'Astrophysique de Paris) (Press Release, Press Release)
