Now, a quick word from our sponsors before tonight's story begins.

Hello, everyone. I'm Olympia. Thank you for being here with me in this wonderful place called

Lights Out Library

and I have a great story to tell you.

We are returning to space tonight.

This journey is going to be our biggest ever.

We are not just going to visit a particular planet

or a part of the solar system no by the power of

imagination we're going to accelerate to several thousand times the speed of light we will escape the

solar system in a matter of seconds and travel to other galaxies.

Along the way, I will tell you about our galaxy, the Milky Way.

We will discuss other galaxies, too, like our destination, Andromeda.

I will explain the mind-blowing distances within and between galaxies,

their populations of billions and billions of star systems, how the existence of galaxies was discovered

and how they are observed. We will discuss mysteries like the possibility of life on these hundreds of billions of planets

they contain, the possible existence of invisible dark matter in the universe, and how fast it is

possible to travel in space.

As usual, you don't need to worry about the complexity of all this.

Everything is going to be easy to understand, even without knowledge, of physics or astronomy.
