Freeman Dyson once imagined a futuristic solution to energy problems: a massive structure, called Dyson Sphere, that would surround a star in order to harness all of its energy. Though this concept feels like something out of a movie, research that has been done recently has sparked efforts to discover megastructures. One of the most remarkable attempts of identifying Dyson Spheres so far is the survey within 5 million stars for infrared excess, with seven promising candidates, even though none of them is confirmed positively yet. These stars, predominantly red dwarfs, may also be going through other activity, for example debris disks or even planetary impacts. These discoveries were certainly fascinating; hopefully, further observations, in say, the James Webb Space Telescope may provide a better understanding of these cases.
