hi, can anyone confirm the 1degree above absolute zero for the
boomerang nebula?
boomerang nebula?

It would be similar to the Freon (sp?) in your AC system, or any expanding gasses which, as you know, drop in temperature when moving from a compressed state to a less compressed state. Just like the AC in your house or car, or even the fire extinguisher.Originally posted by wolram

It could be. Helium will "degrade" at about 2.17*K, and Sodium took it down to 1 millionth *K in the MIT laser experiment. I guess it totally depends on the element, and temperature of course, but that 1*K nebula should certainly apply as a candidate for a Bose-Einstein Condensate for certain elements...

thanks LABGUY, straying from the origonal question, if you can have
a 1k nebula is it going to far to say that there may be bose einstein
condition in space?
Absolute zero is the lowest possible temperature that can be reached, at which point all molecular motion stops. It is equivalent to 0 Kelvin or -273.15 degrees Celsius.
The boomerang nebula is important because it is the coldest known object in the universe with a temperature of only 1 Kelvin. Studying this object can provide valuable insights into the behavior of matter at extremely low temperatures.
The temperature of the boomerang nebula was measured using radio telescopes that detect the radiation emitted by the cold gas and dust in the nebula. By analyzing the intensity and wavelengths of this radiation, scientists were able to calculate the temperature of the nebula.
No, nothing can survive at absolute zero. At this temperature, all molecular motion stops, making it impossible for any form of life to exist.
The boomerang nebula maintains its low temperature through a process called adiabatic expansion. As the gas and dust in the nebula expand and move away from the central star, their temperature decreases. This process continues until the temperature reaches close to absolute zero.
