|Hot spots across Southeastern Europe from 21 to 26 August have been detected with instruments aboard ESA satellites, which have been continuously surveying fires burning across the Earth's surface for a decade. Working like thermometers in the sky, the Along Track Scanning Radiometer (ATSR) on ESA's ERS-2 satellite and the Advanced Along Track Scanning Radiometer (AATSR) on ESA's Envisat satellite measure thermal infrared radiation to take the temperature of Earth's land surfaces.

|Fire burns on the Hill of Kronos next to the site of ancient Olympia, birthplace of the Olympic Games, in southwestern Greece on Sunday, Aug. 26, 2007. A massive effort by firefighters, assisted by water-dropping aircraft and fire trucks, succeeded in keeping a raging blaze away from the 2,800-year-old site - the holiest sanctuary in ancient Greece. Three days of forest blazes throughout the country have left at least 57 people dead, authorities said Sunday.
