Cosmic Microwave Background (CMB) Radiation

The initial generation of light that we can still observe today as the CMB occurred during the recombination epoch, about 380,000 years after the Big Bang. Before this time, the universe was a hot, dense plasma of protons, electrons, and photons. Photons were constantly interacting with the charged particles, making the universe opaque. As the universe expanded and cooled, protons and electrons combined to form neutral hydrogen atoms, reducing the interactions between photons and matter. This allowed photons to travel freely for the first time, resulting in the release of the CMB radiation. This event is sometimes referred to as the "decoupling" of matter and radiation.

Formation of the First Stars

The next significant source of light came from the formation of the first stars, which occurred several hundred million years after the Big Bang. During the period known as the "Dark Ages," the universe had cooled down and was dominated by neutral hydrogen gas. Eventually, regions of slightly higher density began to collapse under gravity, forming the first stars and galaxies. These first stars, often referred to as Population III stars, were massive and short-lived. They ignited nuclear fusion in their cores, producing the first stellar light and reionizing the surrounding hydrogen gas. This period is known as the "Epoch of Reionization."
