| The European Space Agency has revealed the most precise map of the ancient universe ever made. The 50-million pixels all-sky image of cosmic background radiation (CMB) made by the £515 million Planck satellite has already led to new theories of the age, composition and future of the universe. The remarkable image was made by observing microwave radiation across the sky over 15 months, and stripping out dust emissions and radio frequencies from the Milky Way galaxy and more distant objects to leave just the afterglow of the Big Bang. The result is an extremely precise picture of the universe just 380,000 years after the big bang. The data suggests the universe is slightly older than previously thought - 13.81 billion years, 80 million years more than our previous best guess. That's based on new observations of the Hubble constant, the rate at which the universe is expanding. The new estimate of 67.3 km/s/Mpc is slower than previously though. But the data could prove troubling for some scientists, as it includes "large scale anomalies" which point to a preferred direction of energy fluctuations in the universe - the so-called 'Axis of Evil'.
