Euclid’s view of the ‘Morphological Tuning Fork’ of galaxy classifications
Text by Louis Quilley, Francine Marleau, Knud Jahnke
In March 2025 ESA and the Euclid Consortium released the first 63 square degrees of calibrated Euclid science images and catalogues, the Q1 release. At the same time, a set of descriptive technical articles and first scientific papers were released to the public. A second set of publications is now ready and has just been released – the EC issued a press release on this.
We have been using this occasion to dip into the more than 20 million galaxies observed for the Q1 release to re-construct a very classical display of extragalactic astronomy: the so-called ‘Morphological Tuning Fork’ – as seen by Euclid.

Second anniversary of Euclid in space
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
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.

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.
