The science, gently

  • The sun holds more than ninety-nine percent of all the material in the solar system.
  • Sunlight takes about eight minutes to travel from the sun to your window.
  • The sun is a middle-aged star, with billions of calm years still ahead of it.

Wonder together

  • The light on your wall left the sun eight minutes ago; what do you think it passed on the way?
  • What does it feel like to be held without being touched?
  • If the sun had a voice, how slowly would it talk?

Tonight's calm-down

Imagine the sun far below the horizon, still holding the whole solar system, including your bed, gently in place. Nothing needs holding by you tonight. Let the anchor do its work.
Go further together

There's so much more to explore.

The episode is a whole story on its own. But if the wondering keeps going after the audio ends, the Family Guide opens this one all the way up: the same calm voice, turned into something you can do together at the table the next morning.

  • Questions written for your child's age, not just their reading level
