The galaxy’s coldest “stars” may actually be alien megastructures
Quick Summary
Scientists have identified new clues that could help astronomers spot one of the most famous hypothetical alien megastructures: a Dyson sphere. The study finds that red dwarfs and white dwarfs are the most promising stars to examine, since advanced civilizations could potentially build energy-harvesting swarms around them more easily. These objects would stand out by glowing in infrared light instead of visible light, lacking the dusty signatures of ordinary stars, and possibly flickering in unusual ways.
