Oui, il y a bien eu une contamination en France suite à l'accident de Tchernobyl en avril 1986, malgré certaines affirmations officielles de l’époque qui ont tenté de minimiser l’impact.

ASTRRONOMY - Milky Way Through Otago Spires

Explanation: Does the Milky Way always rise between these two rocks? No. Capturing this stunning alignment took careful planning: being in the right place at the right time. In the featured image taken in June 2024 from Otago, New Zealand, the bright central core of our Milky Way Galaxy, home to the many of our Galaxy's 400 billion stars, can be seen between two picturesque rocks spires. For observers in Earth's Northern Hemisphere, the core is only visible throughout the summer. As Earth orbits the Sun, different parts of the Milky Way become visible at different angles at different times of the night. As Earth rotates, the orientation of the Milky Way in the sky also shifts -- sometimes standing vertically as seen in the featured image, and other times stretching parallel to the horizon, making it harder to see. In early June, observers can watch it emerge low on the horizon after sunset and gradually arc upward to reveal its full grandeur.

ASTRONOMY - Eye Sky a Dragon
2025 July 1

Explanation: What do you see when you look into this sky? In the center, in the dark, do you see a night sky filled with stars? Do you see a sunset to the left? Clouds all around? Do you see the central band of our Milky Way Galaxy running down the middle? Do you see the ruins of an abandoned outpost on a hill? (The outpost is on Askold Island, Russia.) Do you see a photographer with a headlamp contemplating surreal surroundings? (The featured image is a panorama of 38 images taken last month and compiled into a Little Planet projection.) Do you see a rugged path lined with steps? Or do you see the eye of a dragon?

ASTRONOMY - NGC 4651: The Umbrella Galaxy
2025 June 30

Explanation: It's raining stars. What appears to be a giant cosmic umbrella is now known to be a tidal stream of stars stripped from a small satellite galaxy. The main galaxy, spiral galaxy NGC 4651, is about the size of our Milky Way, while its stellar parasol appears to extend some 100 thousand light-years above this galaxy's bright disk. A small galaxy was likely torn apart by repeated encounters as it swept back and forth on eccentric orbits through NGC 4651. The remaining stars will surely fall back and become part of a combined larger galaxy over the next few million years. The featured deep image was captured in long exposures from Saudi Arabia. The Umbrella Galaxy lies about 50 million light-years distant toward the well-groomed northern constellation of Berenice's Hair (Coma Berenices).
