Euclid in 2024 and what’s to come in 2025
What an exciting year this was for Euclid and the Euclid Consortium! In February Euclid’s surveys have officially started, the first 14 ‘Early Release Observation’ outreach and early science images have been made public, and now the consortium and ESA are gearing up for the first ‘Q1’ data release of 53 deg² to the world.

Space Warps – Euclid
Discover Space Warps with the Euclid Space Telescope! The Euclid Consortium and the Zooniverse team are excited to launch a new Space Warps project, ‘Space Warps – ESA Euclid’, to find strong gravitational lenses in Euclid survey images. You can contribute to identifying systems that bend the fabric of space itself. Excited?

What Euclid really sees in the sky
Euclid’s goal is to produce scientific insight in the fields of cosmology and astrophysics. New knowledge comes in the shape of understanding of processes, new ‘laws of nature’, or numbers relating different physical properties to each other. However, the Euclid spacecraft initially observes the sky, and its data after a downlink to Earth is processed in a set of complex data analysis pipelines to extract such numbers and relations. Some of the images that have been calibrated to scientific standards that allow such an extraction have already been publicized – but how does Euclid’s raw, unprocessed view into the sky look?

ESA unveils zoom into Euclid’s first large piece of the sky
Euclid has been surveying the sky since 14 February 2024 and data processing is in full swing – the first public release of 53 deg² of science-grade Wide Survey data will take place in March next year. But how much data has Euclid already observed and how can we possibly visualize this? At a rate of 10 deg² per day, the Euclid Wide Survey has already surpassed 1000 deg², that is 5000x the apparent size of the Moon in the sky! Now ESA has put out a first set of images that allow to grasp how much data Euclid is and will be producing.

Galaxy Zoo: Euclid
Euclid scientists need your help. Euclid captures images of tens of millions of galaxies like those we’re showing here. To classify that impossibly-large pile of galaxies, we’re using citizen-science classifications to train AI algorithms. But the AI algorithms need to be ready for the scientists by the end of August – in only one month! We need as many volunteer classifications for teaching the AI algorithms as we can get; our goal is 100,000 classifications. This is Galaxy Zoo: Euclid. Spread the word and dive in!

Euclid Reference Publications: the Euclid Mission Overview
Euclid is a complex mission, consisting of a spacecraft and scientific instruments, a massive cosmological simulation, and large and complex data processing segment to turn instrumental data into scientific meaning. Now, one year after launch, the Euclid Consortium has published a set of five reference papers, providing both the scientific background and an up to date description of the instruments and simulations. Paper 1 (Euclid. I. Overview of the Euclid mission, Euclid Collaboration: Mellier et al. 2024) is giving a full overview of the Euclid mission after launch, ranging from the overall background, the satellite and instruments, the surveys, and finally introduces both the cosmology diagnostics as well as astronomy projects envisioned with Euclid.
