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.
“The clarity and precision of Planck’s map is stunning,” says Richard Easther, an astrophysicist at the University of Auckland in New Zealand, who is not on the Planck team. “It’s as good as anyone could have hoped for.”
