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 1
in Antarctica in 1983. We encounter an
interesting situation when we discuss temperatures in
2 temperatures in Earth orbit actually range from about 20℃
to 120℃. The temperature depends upon 3 you are in direct sunlight or shade. Obviously, -120℃ is colder than our
body can safely endure. Thank NASA science for well-designed space 4 that protect astronauts from these temperature
extremes. The space temperatures just discussed affect only our
areal of the solar 5 . 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 6 . We are taught it is supposedly 7 to have a temperature below absolute zero,
which is -273℃, at which atoms do not move. Two scientists, whose names are
Cornell and Wieman, have successfully cooled down a gas to a temperature barely
8 absolute zero. They won a Nobel Prize
in Physics in 2001 for their work—not a discovery, in this case2.
Why is the two scientists work so important to science
In the 1920s, Satyendra Nath Bose was studying an interesting 9 about special light particles we now call
photons. Bose had trouble 10 other
scientists to believe his theory, 11 he
contacted Albert Einstein. Einstein’s calculations helped him, theorize that
atoms 12 behave as Bose thought—but
only at very cold temperatures. Scientists have also discovered
that 13 atoms can help them make the
world’s atomic docks even more accurate. These clocks are so accurate today they
would only lose one second 14 six
million years! Such accuracy will help us travel in space because distance is
velocity times time (d=v×t). With the long distances involved in space 15 , we need to know time as accurately as
possible to get accurate distance.
