  Scaling properties of the cosmic microwave background (CMB) radiation are
studied using satellite (COBE-DMR maps), balloon-borne and ground-based
(combined QMASK map) data. Quantitative consistency is found between the
multiscaling properties of the COBE-DMR and QMASK CMB maps. Surprisingly, it is
found that the observed CMB temperature multiscaling resembles quantitatively
the multiscaling properties of fluid turbulence, that indicates primordial
plasma turbulence as an origin of the CMB temperature space anisotropy.
