Dyson Spheres Around White and Red Dwarfs: Calculating the Search ⚡ экспресс
Original: "Dyson spheres on H-R diagram"
Scientists have calculated how giant 'blankets' around stars — Dyson spheres — would glow, to help telescopes find traces of aliens.

A giant sphere built around a star to collect its energy is not just a fantasy. If such spheres exist around white dwarfs, they will emit heat in infrared light, and modern telescopes can find them.
🎯 If you built a Dyson sphere around the Sun at the distance of Earth's orbit, its surface would have room temperature — about 300 K.
🎬 Giant spheres around stars have appeared many times in science fiction, for example, in the series 'Star Trek: The Next Generation' (episode 'Relics').
T \propto R_D^{-1/2}
The temperature of the sphere drops inversely proportional to the square root of its radius.
