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

    Re: 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.

    This is not a "confirmation", but the Boomerang nebula, a planetary nebula, is found to be expanding at a rapid rate that is 10 to 100 times faster than other known planetary nebula. This rapid expansion equals a fast drop in temperature, enough to be at just ~1 degree K.

    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?

    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... (?)
