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.
