CMB Polarization Map
NASA's Wilkinson Microwave Anisotropy Probe WMAP has produced a new, more
detailed picture of the infant universe. Colors indicate "warmer" (red) and
"cooler" (blue) spots. The white bars show the "polarization" direction of
the oldest light. This new information helps to pinpoint when the first stars
formed and provides new evidence for the inflationary scenario of the big bang.
