This historical insight is possible because light takes a finite time to travel to Earth from distant galaxies, so looking at these galaxies is akin to seeing them at the time when the light left, sometimes as early in the 13.8-billion-year history of the cosmos as around 300 million years after theLight from these galaxies doesn't remain unchanged over the course of its many-billion-year journey to the 21-foot-wide gold-plated primary mirror of JWST, however.
The expansion of the universe stretches the wavelengths of this light, reducing its energy from the visible spectrum to infrared light. This process is known as"
