First stars in universe were born 100 million years later than previously thought — mashable.com

The very first stars in the universe need to reset their birthday clocks: These ancient objects burst into existence more than 100 million years later than scientists previously thought, according to new research.

New measurements by the European Space Agency's Planck satellite — which studied the cosmic microwave background, or the light left over from the Big Bang — indicate that this period of light began about 100 million years later than Planck's previous estimate. The new results are based on an additional year of observations recorded by the satellite.
