According to Energy Education, “The Dyson sphere or Dyson shell is a theoretical megastructure . . . composed of a shell of solar panels around the star, making it so that all of its energy radiated would hit one of these panels, where its energy could be collected and used.” These are primarily considered science fiction, but physics suggest they may be possible.
Essentially, Dyson Spheres help us find alien life by indicating an advanced civilization. In 1960, Physicist Freeman Dyson proposed that civilizations would build large structures, which can be considered when searching for extraterrestrials. So far, no Dyson Spheres have been found, but knowing they are theoretically possible is a start.
The authors of the study have been investigating infrared signatures around stars within a 1,000 light-year range from Earth, and currently there are seven sources glowing without any explanation for why. While they may not immediately be because of alien life, this is the beginning of expanding this field and paving the way for future discoveries.
