| Abstract | Level Q data represent products suitable for a large variety of purposes in astronomy, except for the core cosmology objectives of the mission. The second Euclid Quick Release (Q2) is an initiative of ESA and the Euclid Consortium. Euclid Q2 include data products from a high-resolution view of the inner bulge region of our Milky Way galaxy. These observations constitute the Euclid Galactic Bulge Survey, they span a total area of 4.8 deg2, and were imaged by Euclid, using its optical VIS camera, over a period of about 24 hours. |

| Temporal Coverage | Q2 data covers nine adjoining fields observed by Euclid on 23rd March 2025 over a period of about 24 hours. |
| 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 maps the geometry of the Universe, reconstructing the evolution of large-scale structures over the past 10 billion years. |
