    : This image shows satellites crossing the night sky above the northern Atacama Desert in Chile over just one hour. It is a stack of a time-lapse video taken on 15 October 2025 about two hours after sunset. A few streaks are caused by planes and can be easily identified by their blinking colored lights, but most trails are due to satellites. Credit: F. Kamphues, ESO/M. Kornmesser

            ⚡ Thunderstorms are antimatter factories - and it happens above your head hundreds of times a day.

            During a storm, intense electric fields inside clouds accelerate electrons to nearly light speed. When they slam into air molecules, they release bursts of gamma radiation called Terrestrial Gamma-ray Flashes. Some of those gamma rays then convert directly into matter via E=mc², spawning an electron alongside its antimatter twin - a positron. These positrons get channeled along Earth's magnetic field lines and escape into space.

            NASA discovered this almost by accident. Their Fermi Gamma-ray Space Telescope - built to hunt cosmic explosions billions of light-years away - kept getting hit by gamma rays from directly beneath it. The energy spike at 511,000 electron volts was the unmistakable fingerprint of positrons annihilating on the spacecraft hull. In one case, Fermi detected a positron beam while flying over Egypt that had been launched by a thunderstorm over southern Africa, thousands of miles away.

            The atmosphere is not just a passive shield. It is an active cosmic forge producing the rarest substance in the universe, right over our heads.

              I searched for "NASA's best photo of Venus" and this is one of the results: a low-resolution picture supposedly taken by the Hubble Space Telescope.

              Why are the photos of Earth’s closest planetary neighbor of such low quality?

                The impact of satellite constellations on astronomy can get much worse. A new ESO study has quantified not only the effects of the satellite streaks, but also the overall increase in the sky brightness due to (a) millions of faint satellites that create a veil of diffuse light, and (b) sunlight scattered by space mirrors, even when not aiming directly at the observer. 👇
