The key visual of the Expedition Sound podcast, which shows Our Sun in the top right corner. From there, a flowing ribbon of colourful wave-like lines travels across the dark blue, star-filled background, weaving past planets of the Solar System. The ribbon continues toward a glowing spiral galaxy in the upper left, visually linking the destinations across the Universe.

La splendida immagine, ottenuta dal telescopio spaziale Euclid e presentata ieri, del cuore affollato della Via Lattea. @science.esa.int

Una fitta distesa di minuscoli punti luminosi e ravvicinati riempie l'immagine. Il colore è quasi uniforme. L'immagine è dominata da tonalità di giallo brillante e oro. Qua e là, compaiono piccoli punti bianchi leggermente più luminosi, con alcuni punti bluastri appena percettibili sparsi tra di essi. Non si notano grandi macchie scure né forti variazioni di colore, il che conferisce all'immagine un aspetto omogeneo.

A very dense field of tiny, closely packed points of light fills the image. The colour is almost uniform, dominated by bright yellow and gold tones across the entire frame. Small white points appear slightly brighter here and there, with a few faint bluish points scattered among them. No large dark patches or strong colour variations are visible, giving the image a smooth, grain‑like appearance.

A dense field of tiny, closely packed points of light fills the image. Most of the background is bright yellow and gold. A broad, irregular dark band runs diagonally across the centre, forming connected black and dark-brown patches. Brighter clusters of pale yellow and white points appear above and below this dark band, with a few slightly bluish points scattered throughout.

Un denso campo di minuscole stelle riempie questa immagine quadrata scattata dal telescopio spaziale Euclid dell'Agenzia Spaziale Europea, ESA. Le aree inferiori e quelle centrali sono dominate da colori giallo brillante e dorato, che formano uno sfondo strutturato simile a sottili brillantini o a sabbia. Macchie di colore marrone scuro e nero attraversano in modo irregolare le regioni gialle, come macchie d'inchiostro o nuvole di fumo. Verso l'angolo in alto a sinistra, i colori virano verso toni violacei e rossastri, fondendosi dolcemente con il campo stellare circostante. Piccoli punti luminosi blu sono sparsi in tutta l'immagine.

Euclid's sharpness and sensitivity allowed it to distinguish several distinct cosmic objects: 🔎 an open star cluster 🔎 an emission nebula 🔎 a dense molecular cloud in the foreground But Euclid was looking for something else. 🔭 🧪 6/8

A very dense field of tiny, closely packed points of light fills the image. The overall colour is warm, with many orange-yellow, gold and white points spread evenly across the scene. Toward the centre, the stars appear more tightly clustered and brighter. A few slightly bluish points stand out among the warmer colours, with no large dark patches visible.

First things first, where did Euclid look more precisely? 🧐 In the upper part of this graphic, you can see the best maps of the Milky Way we have, thanks to ESA's Gaia mission. The central part of our galaxy, called the galactic bulge, is clearly visible in the side-on view. 🔭 🧪 2/8

The image is a composite infographic set against a black background. At the top are three rectangular panels arranged from left to right. The left panel shows a bright horizontal band with a bright central area. The middle panel shows a spiral pattern viewed from above, with a white rectangular outline marking a region. The right panel shows a zoomed-in spiral view labelled ‘Solar System’. Behind these panels, a wide background image filled with densely packed yellow and gold points of light spans most of the width. Along the bottom centre, four numbered rectangular cutouts are shown in a row, each highlighting a different close-up region with varying colours and densities. On the far right, an additional rectangular panel shows a broader view with several numbers marking the locations of the cutouts within it.

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. A rectangular zoom-in panel is overlaid on the main image, showing a close-up view of densely packed stars in yellow, gold, and darker tones.

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.
