Second anniversary of Euclid in space

Consortium, ESA, People, Science, Telescope and instruments / By

It was a hot morning at Cape Canaveral in Florida, on July 1st, 2023, two years ago today. It was the first morning of the 3rd quarter of the year, the earliest possible launch day for Euclid. Late at night there had been some last minute work on the launcher and at 3AM the rocket apparently had still been lying horizontally, but a few hours later it could be seen standing upright with Euclid on top, sheltered by an ESA- and Euclid-themed fairing. The launch was on!

Euclid finds complete Einstein Ring in NGC galaxy

Consortium, ESA, Publication, Science / By

Gravitational lenses are rare in the sky – galaxies bending the light-paths of light from other galaxies behind them to form distorted or even multiple images. Even rarer is a perfect alignment of the two galaxies with us, the obervers, with the light being bent into a so-called Einstein Ring. And the rarest case was now observed by Euclid: this happening in an extremely nearby NGC galaxy.

What Euclid really sees in the sky

Consortium, ESA, Science, Telescope and instruments / By

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

Consortium, ESA, Science, Telescope and instruments / By

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.
