So far, the Boomerang Nebula is the only preplanetary nebula whose temperature has dropped below that of the Big Bang's afterglow, but there's no way it's the only one that ever has.

At a cosmologically crisp –458° Fahrenheit (–272° Celsius), the Boomerang Nebula is the coldest known object in the universe — colder, in fact, than the faint afterglow of the Big Bang ...

The preplanetary nebula IRAS 2006+84051 is hotter than the Boomerang Nebula, but is still an... [+] intermediate phase between a red giant and a planetary nebula/white dwarf stage. ESA/Hubble & NASA ...

The Boomerang Nebula’s central star has lost an entire Sun’s worth of material just since A.D. 500 — an unsustainable mass-loss that will not endure much longer.

The Boomerang Nebula, however, is not quite at that stage, researchers said. It's visible right now because the star's light is being reflected off the dust grains.

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 ...

The Hubble Space Telescope has taken photo images of the “Boomerang Nebula” - the coldest object in the Universe. The nebula is located in the constellation of Centaurus, about 5000 light years from ...

The Boomerang Nebula is located about 5,000 light-years from Earth in the direction of the Southern constellation Centaurus. Submillimeter radio measurements made in 1995 show the deep interior of ...

The Boomerang Nebula is located about 5,000 light-years from Earth in the constellation Centaurus. The red giant star at its center is expected to shrink and get hotter, ultimately ionizing the ...

The Boomerang Nebula is a numbing 1 degree Kelvin, or about -458 Fahrenheit, more than a degree colder than the background radiation of the Big Bang, according to calculations by an astronomy team ...

The Boomerang Nebula is located about 5,000 light-years from Earth in the constellation Centaurus. The red giant star at its center is expected to shrink and get hotter, ultimately ionizing the ...
