A Dyson sphere is a space structure imagined in 1959 by the physicist Freeman Dyson, constituted by an artificial sphere entirely surrounding a star to collect all its radiations for energetic and industrial endings.
Frequently, in S.F., the spherical form is abandoned for less expensive structures: swarm (independent collectors distributed on an imaginary sphere) or ring world (cylindrical ring going around the star in its equator).
