Query: Detection of anisotropy in the Cosmic Microwave Background at horizon
  and sub-horizon scales with the BOOMERanG experiment   BOOMERanG has recently resolved structures on the last scattering surface at
redshift $\sim$ 1100 with high signal to noise ratio. We review the technical
advances which made this possible, and we focus on the current results for maps
and power spectra, with special attention to the determination of the total
mass-energy density in the Universe and of other cosmological parameters.
