What is the coldest place in the world? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6° Fahrenheit (minus 92° Celsius) on a clear winter night - colder than the previous recorded low temperature.

Scientists at the National Snow and Ice Data Center made the discovery while analyzing the most detailed global surface temperature maps to date, developed with data from remote sensing satellites including the MODIS sensor on NASA's Aqua satellite, and the TIRS sensor on Landsat 8, a joint project of NASA and the U.S. Geological Survey (USGS). The researchers analyzed 32 years of data from several satellite instruments that have mapped Antarctica's surface temperature. Near a high ridge that runs from Dome Arugs to Dome Fuji, the scientists found clusters of pockets that have plummeted to record low temperatures dozens of times. The lowest temperature the satellites detected - minus 136° F (minus 93.2° C), on Aug. 10, 2010.

The new record is several degrees colder than the previous low of minus 128.6° F (minus 89.2° C), set in 1983 at the Russian Vostok Research Station in East Antarctica. The coldest permanently inhabited place on Earth is northeastern Siberia, where temperatures dropped to a bone-chilling 90 degrees below zero F (minus 67.8° C) in the towns of Verkhoyansk (in 1892) and Oimekon (in 1933).
