Figure 1.Map of the universe based on cosmic microwave background temperature fluctuations. The whole celestial sphere is mapped into an oval by an equal-area Molleweide projection. The map is in galactic coordinates.

Figure 2.Diagram of the vacuum energy density of the universe versus the matter density, both expressed as a fraction of the critical density (Ov=?vac/?crit, OM=?matter/?crit), which divides open infinite models of the universe from closed finite models. Models consistent with cosmic microwave background data are shown as dots. Those models that are also consistent with the Hubble Space Telescope value of the Hubble constant are shown as larger dots. The contours show the 1-, 2- and 3-standard deviation confidence intervals based on supernova evidence.
