On 19 March 2025, our Euclid mission released its first batch of survey data, revealing an astonishing view of the cosmic web.
With just one scan of its deep fields, Euclid has already detected 26 million galaxies, some as far as 10.5 billion light-years away! This is just a preview of what’s to come, as Euclid will continue mapping the Universe in unprecedented detail.
What’s in this first release?
– Three vast mosaics covering 63 square degrees of the sky
– A catalogue of 380 000 galaxies, classified with AI + citizen scientists
– 500 new gravitational lens candidates, almost all never seen before
– The first hints of Euclid’s full cosmic atlas, which will eventually cover one-third of the sky
This data is a huge leap forward in understanding how galaxies are distributed across the Universe and how dark matter and dark energy shape the cosmos.
Over the next six years, Euclid will revisit these deep fields 30 to 52 times, uncovering billions of galaxies and pushing the astrophysics’ boundaries.
