Question about Size of Universe

The topic of the 'Special Section' of the latest issue
of Science (4 January) is entitled 'Cosmic Web.'

The following is from page 48 (column 1):

"Researchers found that the universe is precisely
13.7 billion years old."

Two paragraphs further on:

"The oldest light, the cosmic microwave background,
appears to emanate from near the periphery of the
observable universe 46.5 billion light-years away."

QUESTION: I had been under the impression that the
distance to the edge (or periphery) of the observable
universe was numerically equal to the age of the
universe. How does this 46.5 billion light-years
correspond to the age of the universe, if at all?

thanks for any help,

Bob
