My partner randomly found a copy of the 1966 book "Intelligent Life in the Universe" by Shklovky & Sagan in a thrift store. It's like a really great intro astronomy textbook, but with a few really WILD statements thrown in here and there.
Like the fact that there isn't life on all the planets in our Solar System somehow apparently disproves Communism? (WHAT. That one really isn't explained).
But the wildest statement: Phobos is probably an artificial satellite. WHAT WHAT WHAT?
