2026 August 15 Bright Perseids from Sweden Image Credit & Copyright: P-M Hedén (Clear Skies, TWAN) Known for its bright and fast meteors, the annual Perseid Meteor Shower comes to planet Earth's skies from a radiant in the heroic constellation Perseus. The popular northern summer celestial spectacle is created as grains of dust cast off along the orbit of periodic comet 109P/Swift-Tuttle vaporize in Earth's dense atmosphere, tracing brief, but beautiful streaks through the night. Taken near the shower's peak of activity on August 12, this composite image recorded two bright perseid meteors and one meteor's watery reflection from a location near the coastal village of Grisslehamn, Sweden. Almost as bright as Altair, brightest star on the scene, the meteors appear along with the faint, diffuse background of the Milky Way. This year, the shower's peak activity coincided with a New Moon, so perseid meteor flashes were undiminished by bright moonlight. And for many skywatchers, this night of bright perseid meteors followed their viewing of the silhouette of the New Moon in a much anticipated solar eclipse. 🔗Discuss 🎞HD

2026 June 25 Anticrepuscular Rays over Sicily Image Credit & Copyright: Marcella Giulia Pace Text: Cecilia Chirenti (NASA GSFC, UMCP, CRESST II) The Sun has just set... in the opposite side of the sky. Pictured here are anticrepuscular rays apparently converging in the east in this image of the limestone plateau in the heart of the Hyblaean Mountains of southeastern Sicily, in Italy. How were these anticrepuscular rays formed, if the Sun wasn't there? After the Sun set (in the west, as usual) its light still illuminated a cloud higher up in the sky. Partially blocked by the cloud, the sunlight produced patterns of light and shadow, crossing the sky in parallel lines. Perspective makes it look like they converge in the east, in the same way that train tracks appear to meet in the distance. This effect can also happen at sunrise, only the directions are exchanged. In rare cases, both crepuscular and anticrepuscular rays can be seen at the same time. 🔗Discuss 🎞HD

🌌 On the evenings of June 8 and 9, Venus and Jupiter will appear within 2 degrees of each other. That’s just over one pinkie width of distance with your hand held at arm’s length, and close enough to simultaneously fit in a pair of binoculars. It will be the closest visible alignment of the two planets in the Northern Hemisphere until 2028 Photograph by Vytautas Kielaitis, Shutterstock

Le Simmetrie Nascoste — Giorgio Parisi (2026) "...negli anni Cinquanta e Sessanta del Novecento, sia nella fisica dei materiali sia in quella delle particelle elementari, i fisici incominciarono a rendersi conto dell’importanza delle simmetrie e del loro rompersi. Le rotture spontanee di simmetria avvengono anche nella vita di tutti i giorni"

“Circadian systems are sensitive to light levels far below what humans typically perceive as bright. If the night sky becomes permanently brighter, the consequences could ripple through ecosystems in ways we do not yet fully understand.” A separate letter from the presidents of the World Sleep Society, European Sleep Research Society, Sleep Health Foundation, Australian Sleep Association and Australasian Chronobiology Society said “circadian disruption is not mere inconvenience; it is a physiological mechanism driving major adverse health consequences” “We do not argue against space innovation,” the letter added, saying that altering the night sky should be treated with the same seriousness as other planetary-scale environmental changes... “The alternation of light and dark is not a trivial background condition. It is one of the oldest organising principles of life on Earth” ✨🌏🌌🎆🌄

Presidents of four international scientific societies representing about 2,500 researchers from more than 30 countries are among those who have raised concerns in letters to the US Federal Communications Commission (FCC)
