Finished! Looks like this project is out of data at the moment!
12 Mar 2026: Fantastic inspecting!! Thanks to all of your hard work we have now completed this new test area of Euclid data. There are some really interesting candidates being posted on Talk, join in the discussion threads. We're now processing the classifications and we'll post some early finds later today. You are all incredible!! Thank you!

Revisiting the ESA Euclid Q1 search – What did we miss?
Please see our blog post update on the ESA Euclid Quicklook-1 (Q1) search. There are some interesting systems we missed first time round. We're learning with each round of classifications on what we got wrong and how we might focus your valuable classifications on the most interesting objects. We are so excited to see these new examples and hope to share the full results of the extended Q1 search, along with other updates very soon.
Space Warps helps to find 497 spectacular lenses in Euclid Quick Look 1 (Q1) data
March 2025
Thanks to your incredible efforts, we are delighted to have found 497 strong lens candidates in the Euclid Q1 data (see a selection below). Over the course of the project we had more than 800,000 classifications from over 1000 wonderful volunteers, and the results are a testament to your hard work. As part of the lens search, we developed the Strong Lens Discovery Engine, a pipeline to search for lenses in Euclid data, of which Space Warps was an integral part.
As part of the Strong Lens Discovery Engine we used multiple machine learning algorithms (including ‘Zoobot’ trained using Zooniverse classifications in Galaxy Zoo) to do an initial sift of the data which the Space Warps volunteers inspected to find the most likely lens candidates. This machine + volunteer partnership will be crucial with the much larger data releases coming soon from the Euclid survey. We also used Euclid’s incredible resolution to produce precise models of all the lens candidates and will continue to analyse these fascinating lenses for many months and years to come!
You can read the full results in the 5 science papers (19 March 2025):
A: Search overview,
B: Lens search around massive galaxies,
C: Finding lenses with machine learning,
D: Double-source-plane lenses,
E: Lens classification combining machine learning and Space Warps.
Thank you again for your incredible hard work in finding these amazing lenses – we couldn’t have done it without you! Keep an eye out for future Space Warps projects – this initial data release was only 0.4% of the sky area of the full survey, so there will be many many more exciting lenses to find soon!
Stay tuned!
