Today, serves as a vital milepost. It is the boundary where the "Dark Ages" ended and the "Age of Reionization" began, turning the universe transparent and paving the way for the stars we see tonight.

: Surprisingly, JWST found more of these distant galaxies than anyone expected. This suggests the early universe was much more efficient at creating light and structure than our old models predicted.

When JWST finally turned its gold-plated mirrors toward the same patch of sky, the "8.7z" galaxy was no longer a mystery. The data revealed:

), light from the earliest galaxies began a multi-billion-year journey toward Earth.

: Analysis of the light showed high amounts of ionized oxygen and hydrogen, signaling that the first generations of stars had already begun "seeding" the universe with the elements necessary for future planets and life.

Here is a story of discovery centered on that distant frontier: The Echo of the First Stars

: Even in the universe's youth, these galaxies were forming stars at incredible rates.

In the vast expanse of the cosmos, "8.7z" refers to a point in time so distant that the universe was only about 600 million years old—a mere infant compared to its current age. At this (notated as
