Coldest Spot On Earth Found By Thermal Camera

Lumistar coldest spot on eath

If one had to guess where the coldest place on Earth is, if you guessed Antarctica you’d be right. The coldest place on Earth has been measured by a space-borne high resolution thermal infrared camera sensor on the recently launched satellite named Landsat-8. On August 10, 2010 during the 24hr dark Antarctic winter months, it was recorded to be a bitter -135.8 Fahrenheit/-93.2 Celsius at a latitude of 81.8 degrees South and a longitude of 59.3 degrees East, at an elevation of about 3,900 meters. It turns out there are many cold spots in Antarctica “strung out like pearls” at each peak along the ridges. The satellite’s sophisticated thermal camera sensor made its way through the dry and clear air that surrounds the interior of Antarctica all the way to the ice’s surface where the temperature was taken. Traditionally, the temperature has to be taken in the air for it to count in the world record books, but scientists are certain the air above the surface is cold enough to beat the current record in 1983 by the Russians also in Antarctica, by at least -4 degrees Celsius/-25 Fahrenheit. In fact, the thermal camera is at such high resolution scientists aren’t sure how to fully calibrate it’s sensor until it has more time to understand all the data Landsat-8 is giving them. Scientists speculate it is in fact be even colder in these spots by several degrees. They hope to get some ground based instruments capable of air temperature there in order to take a measurement and secure the world record. By comparison, the coldest temperature recorded in Alaska and Siberia is about -43/ -45F, and the summit of Greenland being -63C/ -81F. The lowest temperature recorded on Earth’s moon is that of -238C/ -396F.

In case you were wondering if this high resolution thermal sensor also happen to record the hottest place on earth — it did. The hottest surface temperature on earth recorded by Landsat-8 was in Dasht-e Lut salt desert in southeast Iran, where it reached +70.7 Celsius/+159.3 Fahrenheit in 2005.

  15. Wow, this thermal space camera sensor must be unbelievably powerful. Maybe Lumistar can get it’s hands on that tech.

  23. They enjoy a tremendous thermal capacity, certainly to the highest level. They can continue in a single place without a whole lot.

  33. Hey just wanted to give you a quick heads up. The words in your content seem to be running off the
    screen in Chrome. I’m not sure if this is a format issue or something
    to do with internet browser compatibility but I figured I’d post to let you know.
    The layout look great though! Hope you get the
    issue fixed soon. Kudos

  51. Woah! I’m really digging the template/theme of this site.
    It’s simple, yet effective. A lot of times it’s tough to get that “perfect balance” between user friendliness and visual appeal.
    I must say you have done a very good job with this.
    Additionally, the blog has alot of informative articles for those are fans of the other side of the red spectrum.
    Outstanding Blog!
