Timeline for the universe, illustration. This timeline shows key events from the origin of the universe billion years ago to the present day. From left: the Big Bang (the initial formation of the universe), the cosmic dark ages (380,000 years), the first stars (180 million years), the formation of the first black holes and accretion disks (250 million years), the reionization phase (between 150 million and one billion years after the Big Bang), and the formation of the galaxies we see today (from one billion years onwards). Image published in 2018.
