A Dyson sphere is a hypothetical megastructure that would encompass a star and capture a large percentage of its power output, proposed as a signature that a sufficiently advanced civilization's energy needs might leave behind. Physicist Freeman Dyson suggested that searches for such structures could be conducted by looking for unusual infrared emission, since waste heat from a fully enclosed star would radiate at infrared wavelengths.
Facts
Concept Domain Formulated YearA similar idea appeared earlier in Olaf Stapledon's 1937 novel Star Maker, which Dyson credited as an influence. Connections
