In one of the most important cosmological discoveries in years, NASA scientists have captured the most precise image of the universe, shedding light on its origins, age, and providing further evidence for the long-standing Big Bang and inflation theories. In Feb. 2003, a joint NASA–Princeton University satellite, the Wilkinson Microwave Anisotropic Probe (WMAP), produced a high-resolution map that captured the oldest light in the universe. This ancient light, called the cosmic microwave background, is the cooled remnant of the hot explosion known as the Big Bang. “The cosmic microwave light is a fossil,” explained David Wilkinson, after whom the probe was named, “Just as we can study dinosaur bones and reconstruct their lives of millions of years ago, we can probe this ancient light and reconstruct the universe as it was.” (Wilkinson died just before WMAP’s amazing findings were published.)

How old is the universe? What is it made of? For the first time, scientists have clarity.
