Revealed, the Coldest temperature on Earth's surface

Where is the coldest place on Earth? Many people who already know the answer: Antarctic. However, recently scientists uncover the location with the lowest temperature in Antarctica, which means the world's most cold. Temperatures reached minus 93.2 Celsius was recorded on August 10, 2010 in the amount of scattered areas near the ice ridge between Dome Fuji and Dome Argus - the 2 highest peaks in the East Antarctic Plateau.

It still a temporary measuring. Scientists still do the calibration and understand the data taken from Landsat 8 satellite, which was launched in February 2013, also recorded data during 32 years of Moderate Resolution Imaging Spectroradiometer (MODIS) - an instruments on NASA satellites, Terra and Aqua. And a number of other satellites orbiting above the Earth.

The findings beating the previous record of minus 89.2 degrees Celsius which is also located in Antarctica. Precisely at Russian's Vostok research station, which was recorded on July 21, 1983.

"It's hard to imagine that the temperature is very low," said Ted Scambos of the U.S. National Snow and Ice Data Center, Boulder, Colorado in the American Geophysical Union meeting, on Monday, December 9, 2013, as reported by the BBC.
With remote-sensing satellites, scientists have found the coldest places on Earth, just off a ridge in the East Antarctic Plateau. The coldest of the cold temperatures dropped to minus 135.8 F (minus 93.2 C) -- several degrees colder than the previous record. (Picture from: http://www.livescience.com/)
"Supposing, even boiling water was freezing. Temperature was 50 degrees lower than in Alaska and Siberia. Approximately 30 degrees lower than the peak of Greenland," he added. "Making cold weather experienced in some parts of North America included the category of tame."

The scientists found that the coldest time in Antarctic in the dark winter at high altitudes, the air is very dry and sunny. Allows heat very efficiently radiated into space. From outer space, the supercooled dots seen hanging like a pearl in the mountains along the Antarctic.

"We're not going to rush to register it to the Guinness World Records because those numbers are likely to experience adjustment during the next few years," said Dr. Scambos. "However, I am now convinced, we know where the coldest place on Earth, and why."

For comparison, the hottest region on Earth that was ever recorded by the satellite is Dasht-e Lut, a salt desert in southeastern Iran. The temperature reached 70.7 degrees Celsius in 2005.

Meanwhile, the coldest place in the solar system most likely to be in some dark craters on the planet with almost no atmosphere. Temperature of the Earth's satellite, the Moon, previously was ever detected of minus 238 degrees Celsius. *** [EKA | FROM VAROUS SOURCES | BBC | LIVESCIENCE]
