Using parallax calculations, the [[Milky Way]] galaxy alone can be directly observed to have a diameter of approximately 80-100,000 light years. Calculations based on the observed brightness of [[supernova]]e of known energy output can determine the distance to more distant objects. The most distant object known is a star cluster approximately thirteen billion light-years away from Earth, observed by the [[Hubble Telescope]] using gravitational lensing.<ref>Amos, 2004</ref>

Although creationists have at times disputed the size of the [[universe]], virtually none propose that it is less than 12,000 light years across.<ref>Fangrad, Richard, 2007.</ref>
