🪐 The cosmic microwave background—the ancient light that fills all of space—has tiny, almost invisible ripples mapped in detail by telescopes like the Atacama Cosmology Telescope. Studying these tiny differences across the sky lets scientists measure the universe’s age, confirm that galaxies like the Milky Way formed from faint clumps in this early glow, and prove that the universe is expanding almost exactly as predicted since the Big Bang. ✨ #universe⚡#cosmology⚡#microwaves⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
