The interactive reference to the beginning and evolution of the universe.
The first galaxies formed a few hundred million years after the Big Bang, ending the cosmic dark ages. Learn about the epochs of the early universe, the role of dark matter, the first stars, and how telescopes like JWST are rewriting our understanding of cosmic dawn.
The Big Bang timeline traces the universe from the Planck epoch through inflation, the first atoms, the cosmic microwave background, the dark ages, reionization, and the formation of galaxies. This guide explains the key epochs, the evidence from missions like COBE, WMAP, Planck, and JWST, and how the Lambda-CDM model ties the story together.
Galaxies formed from tiny quantum fluctuations in the early universe, growing through gravitational attraction and merging over billions of years. This guide explains the cosmic epochs from the Planck era to the present, the role of dark matter, and the evidence from the cosmic microwave background.
