Today's image features a perspective view of the Alver crater, recently named for Estonian poet Betti Alver (1906-1989). Alver's husband was imprisoned and died in Siberia after World War II, leading Alver to stop writing poetry for many years in protest of Soviet rule. She resumed writing poetry in the 1960s, composing the notable 1966 collection Tähetund or "Starry Hour."
