What Is the Coolest Gas in the Universe? What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃，which in Antarctica in1983. We encounter an interesting situation when we discuss temperatures in .Temperatures in Earth orbit actually range from about +120℃ to -120℃.The temperature depends upon you are in direct sunlight or shade.Obviously，-120℃ is colder than our body can safely endure.Thank NASA science for well-designed space that protect astronauts from these temperature extremes. The space temperatures just discussed affect only our area of the solar .Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun.Astronomers estimate temperatures at Pluto are about -210℃.How cold is the lowest estimated temperature in the entire universe? Again，it depends upon your .We are taught it is supposedly to have a temperature below absolute zero，which is -273℃, at which atoms do not move.Two scientists，whose names are Comell and Wieman，have successfully cooled down a gas to a temperature barely absolute zero.They won a Nobel Prize in Physics in 2001 for their worknot a discovery，in this case. Why is the two scientists work so important to science? In the 1920s，Satyendra Nath Bose was studying an interesting about special light particles we now call photons.Bose had trouble other scientists to believe his theory， he contacted Albert Einstein.Einsteins calculations helped him theorize that atoms behave as Bose thoughtbut only at very cold temperatures. |
