Space Science and Extraterrestrial Life
This cluster of papers explores the search for extraterrestrial life and intelligence, including topics such as astrobiology, SETI (Search for Extraterrestrial Intelligence), galactic habitable zones, global catastrophic risks, the Fermi Paradox, planetary biology, technosignatures, and space exploration.
Papers listed on taxonomy pages are the top few works per node from the OpenAlex snapshot. That list is not exhaustive and is not an endorsement. The topic map and the journal registry remain separate: there is still no authoritative topic-to-venue or topic-to-organization edge. Search is a lexical lookup, not a claim that a venue publishes a topic.
