History of the Universe. Schematic diagram of the major milestones in the evolution of the Universe since the Big Bang, about 13.8 billion years ago. Stages shown include 'Recombination', 'The Dark Ages', the formation of the first astronomical objects, and the formation of the galaxies (right), up to the present day (far right). The yellow labels show the change from fully ionised to neutral (400 thousand years after the Big Bang). Light from the first generation of stars started to ionise the hydrogen in the period of reionisation. After several hundred million years, the gas in the Universe was fully ionised.
