Let us face this question head on.Firstly, there are several lessons to be learned from astronomy and space science for our life on Earth. In science, learning from extreme cases usually gives one insights into the ordinary situation; in medicine, we often learn about diseases and treatments from studying other species. So, in the case of Earth's climate and history, we can learn from other planets. The danger of all-out nuclear war, mercifully now receding after the end of the Cold War, was unique in that, alone of all the perils we face, it endangered not just civilization, but even our biological existence. Other threats, like Ebola virus plagues, global warming, or even a new Ice-Age, may destroy civilization, perhaps irreversibly, but would not wipe out the whole race. The reason given in the mid 1980's was the phenomenon of nuclear winter.
