The Cosmic Dawn is the period in the early universe when the first stars and galaxies began to form, ending the long 'cosmic dark ages' that followed the Big Bang.
It is estimated to have begun roughly 200-400 million years after the Big Bang, approximately 13.4 billion years ago, and lasted for several hundred million years.
Astronomers use powerful telescopes like the James Webb Space Telescope to observe extremely distant, highly redshifted light from these early objects, effectively looking back in time.
It is crucial for comprehending how the universe evolved from its simple beginnings into the complex structure of galaxies, stars, and planets we see today, including our own origins.
