==Results== [[Image:Boomerang CMB.jpeg|thumb|200px|right|CMB Anisotropy measured by BOOMERanG]] Together with experiments like the [[Saskatoon experiment]], [[Mobile Anisotropy Telescope|MAT/TOCO]], MAXIMA, and others, the BOOMERanG data from 1997 and 1998 determined the angular diameter distance to the surface of last scattering with high precision. When combined with complementary data regarding the value of [[Hubble's law|Hubble's constant]], the Boomerang data determined the [[Friedmann equations|geometry of the Universe]] to be flat,<ref name="Nature_27Apr00"/> supporting the [[supernova]] evidence for the existence of [[dark energy]]. The 2003 flight of Boomerang resulted in extremely high [[signal-to-noise ratio]] maps of the CMB temperature anisotropy, and a measurement of the polarization of the [[Cosmic microwave background|CMB]].<ref name="MacTavish">{{cite journal|title=Cosmological Parameters from the 2003 Flight of BOOMERANG|date=August 2006|journal=[[Astrophysical Journal]]|volume=647|pages=799β812|last1=MacTavish|first1=C.
