Webb Telescope Sees 13 Billion Years Back! 🤯

Ever stared at a breathtaking galaxy photo and wondered, "How do scientists know when that light first left?" 🌌
In this video we turn a single telescope snapshot into a genuine time machine.

You'll see how the expanding universe quietly stretches every light wave during its multi-billion-year journey, and how elements like hydrogen and iron stamp their own spectral "bar-codes." By matching each pristine lab pattern to its red-shifted twin, astronomers read a galaxy's age as easily as a date stamp. 🛰️

We'll pull apart a jaw-dropping James Webb deep-field where some waves arrive stretched ten-fold-revealing galaxies less than 400 million years after the Big Bang. 🤯 You'll discover why colour really does equal time, why "redshift" is more than a buzzword, and how stellar hues inside the same image unveil each galaxy's personal life story.

By the end you'll have a party-trick explanation for anyone who asks "But how do we know?"
