  28.       Detailed studies of the spectrum of the cosmic microwave
  29. background using the COsmic Background Explorer satellite launched in
  30. 1989 allow one to study energy release later than 1 year after the Big
  31. Bang.  Studies of the temperature fluctuations around the sky allow one
  32. to see structures as they existed 300,000 years after the Big Bang; but
  33. these structures were formed less than 1 nanosecond after the Big Bang
  34. and provide us with our earliest observed datum about the history of
  35. the Universe.
