Do the more extreme phases of matter like Bose-Einstein Condensate and Quark-Gluon Plasma still exist in nature?

Or are they only attainable under laboratory conditions currently? Or are there other, more exotic phases of matter that I'm unaware of that fit the bill?

Neutron and white dwarf stars are made of degenerate matter that could be described as a Fermi-Dirac rather than a Bose-Einstein condensate (although not the same as a fermionic condensate). Neutron star interiors are believed to be superfluid, which is a form of Bose-Einstein condensation. Also inside neutron stars it is possible that something like a quark-gluon plasma exists, but this is unknown for sure.
