The coldest place on Earth has been measured by satellite to be a bitter minus 93.2 Celsius (-135.8F). As one might expect, it is in the heart of Antarctica, and was recorded on 10 August, 2010.
Researchers say it is a preliminary figure, and as they refine data from various space-borne thermal sensors it is quite likely they will determine an even colder figure by a degree or so.
The coldest place in the Solar System will likely be in some dark crater on a planetary body with no appreciable atmosphere. On Earth's Moon, temperatures of minus 238C have been detected.
