The Universe Is Expanding Surprisingly Fast


The universe really is expanding faster than scientists had thought, new research suggests.

Astronomers have pegged the universe's current expansion rate — a value known as the Hubble constant, after American astronomer Edwin Hubble — at about 44.7 miles (71.9 kilometers) per second per megaparsec. (One megaparsec is about 3.26 million light-years.)
