Geoengineering

Terraformation, or more broadly geoengineering, is the process of modifying planetary features such as geography, temperature or atmospheric composition to make it more habitable (specifically, but not necessarily, "Terra-" or Earth-like). Artificially introducing ammonia, methane or other hydrocarbons into Mars' atmosphere to generate a warming effect is a theoretical example of terraforming, and also highlights the ethical complexities of fundamentally modifying an environment which might harbor its own shadow ecosystem. One hypothesis for FRBs (fast radio bursts) is that these may be evidence of sterilizing terraforming events.

Detectability

  • Although a geoengineered planet would conceivably be no different than a naturally developed world, it's possible that the actual process of geoengineering an exoplanet may be detectable.
