Engineering on an astronomical scale, or astronomical engineering, i.e., engineering involving operations with whole astronomical objects (planets, stars, etc.), is a known theme in science fiction, as well as a matter of recent scientific research and exploratory engineering.
Planetary engineering is the development and application of technology for the purpose of influencing the environment of a planet.Planetary engineering encompasses a variety of methods such as terraforming, seeding, and geoengineering.
Moving Earth is a theoretical astroengineering concept that involves physically shifting Earth farther away from the Sun to protect the planet's biosphere from rising temperatures. These expected temperature increases derive from long-term impacts of the greenhouse effect combined with the Sun's nuclear fusion process and steadily increasing ...

Astroengineering is the extension of megascale engineering to megastructures on a stellar scale or larger, [3] such as Dyson spheres, [4] Ringworlds, and Alderson disks. Several megascale structure concepts such as Dyson spheres, Dyson swarms, and Matrioshka brains would likely be built upon space-based solar power satellites. Other planetary ...
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. [3] It has two major and overlapping branches: aeronautical engineering and astronautical engineering.
One of the simplest examples of a stellar engine is the Shkadov thruster (named after Dr. Leonid Shkadov, who first proposed it), or a class-A stellar engine. [5] Such an engine is a stellar propulsion system, consisting of an enormous mirror/light sail—actually a massive type of solar statite large enough to classify as a megastructure—which would balance gravitational attraction towards ...
The Center for Astrophysics | Harvard & Smithsonian (CfA), previously known as the Harvard–Smithsonian Center for Astrophysics, is an astrophysics research institute jointly operated by the Harvard College Observatory and Smithsonian Astrophysical Observatory.
