Postcard from Estonia
In May 2009 I received also this great card showing a "white night" in Tallinn - the time when the whole sky stays luminous even at midnight, with the brightest nights being those ten days before and after the summer solstice. This specific picture was taken at 1.21 a.m. Very interesting. Astronomical phenomena are covered also on the fine stamp from the EUROPA project, issued on 5 May 2009, along with another stamp showing the cell structure of the universe. Thank you Susa!
