"Dark energy" rules the universe- "This finding provides strong support for a universe which is dominated by a kind of energy we've never directly observed," says Chaboyer. "Observations of distant supernova have suggested for a few years that dark energy dominates the universe, and our finding provides independent evidence that the universe is dominated by this type of energy we do not understand."

Age of the universe revised, again. In a study published today in the journal Science, a team of researchers says the universe is between 11.2 billion and 20 billion years old. Most estimates in recent years have ranged between 10 billion and 15 billion years. Last year, data supplied by the Hubble Space Telescope led to an apparently refined estimate of 13 billion to 14 billion years.
