This color image shows a young man from the shoulders up smiling directly at the camera. He has dark, tightly curled hair and is wearing a dark, thin-framed pair of eyeglasses and a mustard-yellow T-shirt. The background is a soft-focus, shallow depth-of-field view of green leafy plants and foliage, with some architectural elements faintly visible, suggesting an outdoor garden or park setting during the daytime. The lighting is soft and natural. On the bottom-left corner of the image is text that says 2026 IPAC Visiting Graduate Student Research Fellow; in the bottom-right corner is an orange box with text that says "Alex Rodriguez University of Michigan Using weak lensing to detect cosmic filament IPAC Advisors: Andreas Faisst & Kyle Finner."

No less than 60 million stars in one image. It's possible thanks to ESA's Euclid mission. For just one day, Euclid turned its gaze to the crowded heart of the Milky Way and captured the largest, most detailed photo ever taken of our galaxy's centre in visible light. Let's dive deeper 👇 🔭 🧪 ☄️ 1/8

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.
