Get your groove on - it's Friday!

Did you know that the coldest known place in the universe is the Boomerang Nebula?

From Space Telescope.org:

The Boomerang Nebula is one of the Universe's peculiar places. In 1995, using the 15-metre Swedish ESO Submillimetre Telescope in Chile, astronomers revealed that it is the coldest place in the Universe found so far. With a temperature of -272 °C, it is only 1 degree warmer than absolute zero (the lowest limit for all temperatures). Even the -270 °C background glow from the Big Bang is warmer than this nebula. It is the only object found so far that has a temperature lower than the background radiation.

It's cold outside, there's no kind of atmosphere... etc (showing my age here folks).
