Precision Cosmology : The First Half Million Years Apr 2026

A "timeline of transparency"—showing the transition from a glowing orange wall of plasma to the first streaks of clear light, eventually fading into the "Dark Ages" before the first stars turned on.

Contrast the "guesswork" of 20th-century astronomy with modern missions like Planck . We’ve moved from "the universe is roughly 10–20 billion years old" to "it is exactly 13.787 ± 0.020 billion years old." Key "Stats" to Highlight Precision cosmology : the first half million years

This sounds like a deep dive into the and the Cosmic Microwave Background (CMB) . Since the first 500,000 years set the stage for everything we see today, a great feature would focus on how we use that ancient light to "weigh" the universe.
