The Planck observatory spent four and a half years studying the evolution of stars and galaxies.
It was designed to detect faint traces of radiation from the Big Bang – also known as the Cosmic Microwave Background (CMB).
“Planck has provided us with more insight into the evolution of the Universe than any mission has before,” says Alvaro Giménez, ESA’s Director of Science and Robotic Exploration.
“Planck’s picture of the CMB is the most accurate ‘baby photo’ of the Universe yet, but the wealth of data still being scrutinised by our cosmologists will provide us with even more details.”
