Studies of craters in the Baltics (Estonia) are giving insights into the many impacts that have peppered the Earth over its long history. In southeastern Estonia, scientists have dated charcoal from trees destroyed in an impact to prove a common origin for two small craters, named Illumetsa. A third submarine crater located on the seabed in the Gulf of Finland has been measured and dated with with precision. Results will be presented by two teams of researchers at the European Planetary Science Congress (EPSC) 2017 in Riga, Latvia, on Monday, 18th September 2017.
