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

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?

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... (?)

thanks once more labguy, the posibilities get more interesting...
