A team of scientists is investigating ways of detecting exo-civilizations aside from just radio signals as with SETI: JUNE 19, 2020 Does intelligent life exist on other planets? Technosignatures may hold new clues. by University of Rochester https://phys.org/news/2020-06-intelligent-life-planets-technosignatures-clues.html Two methods of detection mentioned in the article are detection from reflected light from solar panels or detection or pollution such as CFCs. However, even on our planet the number of solar panels would not be such that they would add appreciably to the Earth light. And CFCs presence might be short lived as it has been on our planet, having been banned. Could we instead detect the light on the night side coming from all the artificial lighting that would be used in a civilization?

Hi, does anybody know about a mod that adds real space telescopes? I would love to have Fermi, Chandra, Spitzer, Kepler, HST and so on in my install, but I can't seem to find any.
