Europe turns off Planck

Europe turns off Planck.

Planck operated four-and-a-half years, three times longer than originally planned. Launched in May 2009 on an Ariane 5 rocket shared with ESA’s Herschel telescope, Planck measured the cosmic fingerprint of the Big Bang, detecting subtle variations in background light originating 380,000 years after the genesis of the universe.
