Astronomers want to plant telescopes on the Moon. The lunar surface offers advantages for infrared and radio astronomy, despite the challenges. By Ramin Skibba, Inside Science | Published: Tuesday, January 19, 2021 Astronomers want to plant telescopes on the Moon | Astronomy.com (See the link there to a journal special issue exploring the idea.) I speculated about the possibility of detecting exo-civilizations optically in this Kerbal forum post: How large a space telescope do we need to see exo-civilizations? - Science & Spaceflight - Kerbal Space Program Forum
Let‘s imagine that an alien spaceship or probe is coming in our solar system from interstellar space - How close would it have to be that we would be able to detect it and which methods could be used? Is there even a chance that we discover it until it has almost reached earth?
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 E
So doing alot of reading about space-time lately and ran across this very appropriate quote yesterday. http://www.householdgigs.com/2016/05/05/fermi-paradox/ So the above is just coincidentally in my reddit stream this AM and I was reading down the list wondering why it was new science and I am reminded of the Ravolli quote, and I though if this is not an example of guessing then I don't know what is. How would I solve the problem. Before I got a few paragraphs down I realized that it was a dirty laundry list of guesses, many of them rather uninformed. So here is it, we have 1
