Briefings

The European Space Agency's Euclid mission has released its first data product, a 60-square-degree sky map containing individual galaxy targets. This initial release includes images of prominent objects such as the Horsehead Nebula and the Perseus cluster, marking a significant step toward a comprehensive 3D sky map. The data was obtained using a few days of observations, providing a foundational dataset for future research.

Key points

• Euclid's first data release includes a 60-square-degree sky map with individual galaxy targets.
• The initial release features images of the Horsehead Nebula and the Perseus cluster of galaxies.

Context

The ESA's Euclid mission has already provided early results, including a 60-square-degree sky map created from a few days of observations. This release marks a critical step toward the mission's goal of mapping the entire sky in 3D.

Limitations

The evidence is limited to a single data release containing a 60-square-degree sky map. It does not specify the date of the observations, the specific instruments used, or the number of galaxies included in the initial release.
