"Goldilocks and the Three Planets"
Once upon a time,
there was a little girl
with short blonde curls
who wanted to explore space.
So Goldilocks got into her spaceship,
and she traveled a long, long way
in search of planets to explore.
The first planet she found was too hot!
It snuggled up right next to its sun,
and even the rocks melted.
The next planet she found was too cold!
It was far, far away from its sun,
and even the air was frozen.
So Goldilocks went home to her library.
She turned on her computer and
took out her books and studied.
She read all about stars and planets
and something called physics.
Then next time Goldilocks
went exploring in her spaceship,
she looked for suns with planets that
were not too close and not too far.
These were much better planets.
Some were a little warm, or a little cold,
so she kept looking for more middle ones.
Soon Goldilocks found a planet that was just right!
It was not too hot or too cold, too big or too small,
and it had soft soil for growing yummy things.
Goldilocks got out of her starship
and put up a habitat dome and
began to plant a garden.
She was very happy in
her new home, and people
began to say that such planets
were in "The Goldilocks Zone."
And she's still there!
Eventually the aliens came home,
but that's another story.

"Goldilocks and the Three Bears" is a fairytale about boundaries and moderation. Read a version online, or enjoy a video.
"The Goldilocks Zone" is the area of space around a star where planets are likely to have liquid water on the surface, and therefore may be habitable for life as we know it. (Life not as we know it may prefer other environments.)
