The universe is a little older and perhaps a bit stranger than previously thought, according to the best measurements ever taken of the radiation left over from just after the Big Bang. Presented March 21 at a press conference in Paris, the data from the Planck satellite combine to form a map of the remnant glow that largely affirms scientists' theories about the universe's early history. But the results also reveal a few quirks that scientists will have to explain.
ââ¬ÅThe clarity and precision of Planckââ¬â¢s map is stunning,ââ¬Â says Richard Easther, an astrophysicist at the University of Auckland in New Zealand, who is not on the Planck team. ââ¬ÅItââ¬â¢s as good as anyone could have hoped for.ââ¬Â
Launched by the European Space Agency in 2009, the Planck satellite scans the sky for the cosmic microwave background, radiation that dates back to about 380,000 years after the Big Bang. That radiation was originally about 2,700ð Celsius but has cooled to a mere 2.7 degrees above absolute zero. Planck is essentially a supersensitive thermometer that can probe the temperature of this radiation to millionths of a degree.
