How Astronomers Measure the Age of Stars

How do we know how old a star is? How can something so distant, so unreachable, still leave clues behind?

In this episode, we gently explore how astronomers measure the age of stars. Through color and brightness. Through slow changes in heat. Through the patient language of physics written into their light.

There is no rush to understand it all. Only soft ideas, drifting one by one, like constellations forming without effort.

As you listen, let time feel wide and gentle. Let the thought of ancient starlight be something steady, not heavy.

You are here for only a moment. But the stars have been keeping time for you.

And tonight, you can rest while they continue.
