Astronomical Calendar: 2018 June

Photograph from a Soviet Academy of Science 1927 expedition led by Leonid Kulik shows hundreds of trees fallen from a huge explosion, now known as the Tunguska Event, which occurred on June 30, 110 years ago. Occurring in a remote area of Siberia near the Stony Tunguska River in 1908, no known person actually observed the explosion, which is speculated to have been caused by an air burst of a meteor, asteroid, or comet fragment.
