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.

Euclid Reference Publications: the Euclid Instruments
In our mini-series about the Euclid Consortium’s set of new reference papers we are now turning to instrument descriptions: Paper 2 (Euclid. II. The VIS Instrument, Euclid Collaboration: Cropper et al. 2024) describe the VIS instrument, papers 3 and 4 (Euclid. III. The NISP Instrument, Euclid Collaboration: Jahnke et al.; Euclid. IV. The NISP Calibration Unit, Euclid Collaboration: Hormuth et al.) the NISP instrument.

Euclid Reference Publications: the Flagship Simulations
In our final post on the Euclid Consortium’s new set of reference papers we are turning to an essential part, the final ingredient to enable Euclid’s cosmology goal: Paper 5 (Euclid. V. The Flagship galaxy mock catalogue: a comprehensive simulation for the Euclid mission, Euclid Collaboration: Castander et al. 2024) is about the newly completed cosmological simulation, the Euclid Flagship Simulation, providing a fully-controlled input for testing and characterising the Euclid science pipeline.
