Stars shine in the sky.

People see them at night.

They are bright.

But some stars hide.

You cannot see them.

They are there.

Scientists know this.

These stars are different.

They do not glow.

Long ago, people look up.

They see only bright stars.

The hidden ones stay secret.

Now, we have tools.

The tools find them.

People ask, "How?"

The sky is big.

It holds mysteries.

Stars you can’t see are real.

They wait for us to learn about them.
