Today's interesting fact has to do with the coldest place in the known universe.
You might find this hard to believe, but by studying the sky with telescopes, both visual and radio, they've been able to show that the temperature of the universe is pretty constant.
The coldest places we've found yet are not in outer space, not in the depths between the stars or galaxies.
The coldest places we've found so far was generated using our own refrigeration equipment.
Absolute zero corresponds to –273.15 degrees Celsius (or –459.67 degrees Fahrenheit).
Scientists have gotten matter to within 100 picokelvins (pK), or 0.000 000 000 1 of a Kelvin of absolute zero.
