With our first data release in November just around the corner, scientists and engineers from across the UK will soon be on the road again! Catch us at @newscientist.com's New Scientist Live, 10-12th October 2026, for the return of Euclid, the #darkuniversedetective 🕵️‍♀️

A poster that says "We're exhibiting at New Scientist Live" with the dates 10-12 October. The poster has a purple background with triangular yellow, blue and purple shapes.

One of our volunteers of the Euclid exhibit at the Royal Society Summer Science exhibition is standing and wearing a white Meta Quest 3 VR headset. They are wearing a white t-shirt and green lanyard, standing in front of a photo of the galactic centre, taken by Euclid. The photo is displayed on LED backlit fabric and contains 60 million stars amongst pink, orange and yellow gas and dust.

This collage with observations of the Euclid space telescope shows a grid of small, dark panels filled with tiny points and faint smudges of light. The lights vary in brightness and colour, including white, blue, yellow, and orange, with some appearing as dots and others as slightly blurred shapes.

From ESA: A dense field of tiny stars fills this square image taken by the European Space Agency’s Euclid space telescope. The lower and central areas are dominated by bright yellow and gold colours, forming a textured background similar to fine glitter or sand. Dark brown and black patches cut irregularly through the yellow regions, like ink stains or clouds of smoke. Toward the upper left, the colours shift to purple and reddish tones, blending gently into the surrounding star field. Small blue points of light are scattered across the image.

A collage of fourteen by eight squares containing examples of gravitational lenses. Each example typically comprises a bright centre with smears of stars in an arc or multiple arcs around it as a result of light travelling towards Euclid from distant galaxies being bent and distorted by normal and dark matter in the foreground. In some rare cases the smearing is in a complete ring, creating a so-called Einstein Ring.

Artist impression of the Euclid mission in space. The spacecraft is white and gold and consists of three main elements: a flat sunshield, a large cylinder where the light from space will enter, and a 'boxy' bottom containing the instruments. The spacecraft is shown half in the shadow, because the sunshield will always be faced in the direction of the Sun and thus protecting the telescope from the light of the Sun. The background is a realistic representation of a deep field view of the night sky, with many galaxies visible. On the bottom half of the image, an artistic representation of the cosmic web is overlayed over the galaxies. The cosmic web is the scaffolding of the cosmos on which galaxies are built, consisting primarily of dark matter and laced with gas. The cosmic web is here represented with a grid and a two-dimensional representation of a cosmological simulation.
