The universe is a little older than previously thought

Scientists using data from the ESA Planck mission have measured the age of the universe to be a little older — about 100 million years older — than previously thought. The official age, based on measurements of the cosmic microwave background, is now 13.8 billion years. Also, the proportions of matter and dark energy have changed a little, with slightly more matter (‘normal’ matter + dark matter) and slightly less dark energy than previously measured.
