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. Each panel has a small label with letters and numbers at the bottom.

Erm... I might have just got a little bit too carried away on the BBC World Service, waxing lyrical about the gorgeousness of the @ec-euclid.bsky.social image of the heart of the Milky Way: "swirling golden cloudy fuzziness" "the cosmos scattered with glitter" 😂 ☺️🔭 📷: www.esa.int/Science_Expl...
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.

This time, they've turned ESA's Euclid to the most crowded patch of sky we have. Stay tuned tomorrow as we reveal this image at 12:00 CEST 🤩 🔭 🧪☄️ 2/2
A wide, horizontal image shows an oval, map-like view set against a black background. Across the centre of the oval runs a bright, narrow band filled with countless tiny points of light, denser and brighter than the areas above and below it. The band looks slightly mottled, with lighter and darker patches mixed together, similar to a thin stripe of dust or mist stretched across a surface. One zoom-in panel is overlaid on the main image. The panel has questions marks drawn inside it.
