L'origine extraterrestre de l'or
Le saviez-vous ? L'or a créé bien avant la naissance de la Terre, lors de violentes explosions ou collisions d’étoiles. Comme la plupart des éléments présents sur notre planète, il est donc d’origine extraterrestre.Explications avec Jérôme Margueron, chercheur au CNRS et directeur de l'International L'origine extraterrestre de l'or

Just as an image conveys data visually, sonification conveys data with sound. No two people will explore Rubin’s images the same, & no two listening experiences will be the same. 🔭🧪

🧪⚒️ #NODSSUM cruise - WOW - Wainting on Weather with a multibeam survey and no Ulyx dive yesterday- after 5 days of work at the radioactive waste dump site. After 5 Ulyx dives we now located >1200 barrels in sonar maps, and sediment/water/fish sampling is well on the way… more details later…

🧪⚒️ #NODSSUM cruise - we arrived to the radioactive waste dump site 2 days ago & AUV UlyX is brings up sonar data that will guide our sampling strategy. After checks for radioprotection, sonar data (500 Gb) transfer via the sturdiest hard drive ever - rated 6000m depth in a tinanium bottle.

Composée de plus de 1100 images prises par l’Observatoire Vera C. Rubin (NSF-DOE), cette image révèle une immense variété d’objets célestes, illustrant la richesse des domaines scientifiques que Rubin va révolutionner grâce à son relevé décennal du ciel, le Legacy Survey of Space and Time. Elle contient environ 10 millions de galaxies, soit environ 0,05 % des quelque 20 milliards de galaxies que l’observatoire Rubin devrait capturer au cours des dix prochaines années.

A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. The image focuses on a collection of interacting galaxies connected by delicate streams of stars. At top center lies a large elliptical galaxy that is dense and smooth, like a polished stone glowing with golden light. Like delicate spider silk or stretched taffy, these stellar bridges link the large elliptical to the few larger galaxies beneath, evidence of past collisions.

All throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black.

A cosmic tapestry of glowing tan and pink gas clouds with dark dust lanes. In the upper right, the Trifid Nebula resembles a small flower in space. Its soft, pinkish gas petals are surrounded by blue gas, and streaked with dark, finger-like veins of dust that divide it into three parts. It radiates a gentle, misty glow, diffuse and soft like the warmth of breath on a cold hand. To the lower left, the much larger Lagoon Nebula stretches wide like a churning sea of magenta gas, with bright blue, knotted clumps sprinkled throughout where new stars are born. Both nebulae are embedded in a soft tan backdrop of gas that is brighter on the left than on the right, etched with dark tendrils of dust and sprinkled with the pinpricks of millions of stars.

Unlike most telescopes, the just-completed Vera C. Rubin Observatory, atop Chile’s Cerro Pachón, takes the big picture. Equipped with an 8.4-meter main mirror and a 3200-megapixel camera, it will capture the entire visible sky every 3 days before starting again. Algorithms sensitive to anything that changes will find billions of previously unidentified objects, including Earth-threatening asteroids and exploding stars called supernovae.
