Stellar engineering

Stellar engineering is a type of engineering (currently a form of exploratory engineering) concerned with creating or modifying stars through artificial means.

While humanity does not yet possess the technological ability to perform stellar engineering of any kind, stellar manipulation (or husbandry), requiring substantially less technological advancement than would be needed to create a new star, could eventually be performed in order to stabilize or prolong the lifetime of a star, mine it for useful material (known as star lifting) or use it as a direct energy source. Since a civilization advanced enough to be capable of manufacturing a new star would likely have vast material and energy resources at its disposal, it almost certainly wouldn't need to do so.

Many science fiction authors have explored the possible applications of stellar engineering, among them Iain M Banks, Larry Niven and Arthur C. Clarke.

In the novel series The Book of The New Sun by Gene Wolfe, the brightness of Urth's sun seems to have been reduced by artificial means.

In the season 3 (1989) episode "Take Me to Your Leader" of the 1987 Teenage Mutant Ninja Turtles cartoon, Krang, Shredder, Bebop and Rocksteady use a Solar Siphon to aim towards the Sun, and store the solar energy into compact batteries, freezing the Earth making it too cold for people to resist them.

In episode 12 of Stargate Universe, Destiny was dropped prematurely out of FTL by an uncharted star that the crew determines to be artificially created and younger than 200 million years old with an Earth-sized planet containing a biosphere exactly like Earth's being the only planet in the system.
