At a cosmologically crisp one degree Kelvin (minus 458 degrees Fahrenheit), the Boomerang Nebula is the coldest known object in the Universe -- colder, in fact, than the faint afterglow of the Big Bang, which is the natural background temperature of space. .

Located about 5,000 light years away from Earth, the Boomerang Nebula is the coldest place found in the universe so far. The temperature of the nebula has been measured at -272.15 degrees Celsius/-457.87 degrees Fahrenheit.
The Tulip Nebula in nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula the glowing cloud of interstellar gas and dust. About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms at the center of this composite image. HDE 227018 is the bright star very near the blue arc at the cosmic tulip’s center.
With a surface temperature of -364 degrees Fahrenheit (-220 degrees Celsius), the extrasolar planet known as OGLE-2005-BLG-390L b is likely the coldest alien world. It is about 5.5 times as massive as Earth and thought to be rocky. It orbits a red dwarf star about 28,000 light-years away, making it the most distant exoplanet currently known.
"...the faintest twinkle of starlight was a real connection between my comprehending eye along a narrow beam of light to the surface of another sun. The photons my eyes detect (the light I see, the energy with which my nerves interact) came from that star." Phil Hellenes
