Oldest light in the universe

This map depicts the oldest light in our universe, some 370,000 years ago. The data sent in from the Planck mission now puts the universe's age at about 13.8 billion years old, or some 100 million years older than earlier estimates. Also, the data suggests that the universe expanded at a very rapid rate shortly after the Big Bang. Scientists reacting to the news expressed delight and surprise at the existence of features which they said challenge conventional understanding of the universe.
