An article by Mario Livio recently published in Nature reports on an 11-page essay Winston Churchill wrote on alien life in September 1939 which was entitled “Are We Alone in the Universe?” Livio provides an excellent detailed analysis of the Churchill essay from a scientific perspective. The Nature article also claims that this Churchill manuscript, which is held by the collection of the National Churchill Museum in Fulton, MO., “has never been published or subjected to scientific or academic scrutiny.” However, as pointed out by Richard Langworth at the Churchill Project, a version of the essay was published as “Are There Men on the Moon?” in the Sunday Dispatch (March 8, 1942) and reprinted in The Collected Essays of Sir Winston Churchill (1975). The full-text of “Are There Men on the Moon?” is available from the Churchill Project.
