The first global document that proposes a definition for Astronomy Literacy, “Big Ideas in Astronomy: A Proposed Definition of Astronomy Literacy”, was published in open-access by the International Astronomical Union (IAU).
This document raises the question: “What should citizens, anywhere on the planet, know about astronomy?”. It presents eleven “big ideas”, such as “We are all made of stardust”, or “We may not be alone in the Universe”, each of them structured in seven to ten supporting concepts.
