The theory that Lut is the thermal center of the earth was proposed by Professor Stratil Sauer from the University of Vienna in Austria in 1952. After some aerial analysis, the west part of Nosrat Abad, Rig-e- Yalan introduced as the hottest place on earth. Theodore Mono confirmed the mentioned area among the hottest places on
earth. According to NASA’s maps, the hottest temperature on earth (70.7 centigrade Celsius) was recorded in the lowest area of Lut —an area in the east of Kaluts— in 2005.
Iranian researchers, including Professor Kardavani and Mahmoudi believe the hottest place of earth is located
somewhere in this desert. Due to extreme heat, the best months to visit Dasht-e Lut are from November through February.
Lut Desert Inscribed on World Heritage List (UNESCO) as Iran’s First Natural Site.
