ESA Datalabs Euclid Hackathon 2026

23 to 26 November 2026

On 12 November 2026, the Euclid First Public Data Release (DR1) will open ~2,000 square degrees of sky — one seventh of the planned Euclid Wide Field — to the world. At this scale, the rarest objects in the Universe are waiting to be found: galaxies of unusual morphology, strong gravitational lenses, edge-on protoplanetary disks, collisional ring galaxies, and phenomena no one has yet looked for. These astrophysical anomalies are often our most informative probes of galaxy evolution and cosmology, precisely because they are so rare. We invite the wider community: astronomers, computer scientists, students, and the simply curious, to hunt for them.

This four-day workshop and hackathon will be held at the European Space Astronomy Centre (ESAC, Madrid, Spain) on the 23rd – 26th of November, 2026 and there will be no conference fees.

The first two days will introduce the Euclid mission and its data, alongside ESA's science platforms (the Euclid Data Space (EDS), ESA Datalabs (EDL), and ESASky) and the anomaly-detection methods that make discovery at this scale possible, including the AnomalyMatch tool developed at ESA.

The final two days take the form of a competition. Teams will go head-to-head to surface the rarest and most remarkable objects in DR1, using benchmarked ESA methods or approaches of their own. The rare objects found by each team will be scored by their rarity and scientific value, with the top scoring teams winning prizes.

Every anomaly uncovered will feed into a shared legacy: a scientific catalogue, released as an ESASky target list and written up for a peer-reviewed journal, with every contributing participant credited as a co-author.
