Like a big city sparkling with lights, our galaxy, the Milky Way, glitters with the light from billions of stars. We live in the outskirts of this immense cosmic city.

(DESCRIPTION) 
 A starry sky above a hill. Red and white light in the sky fades to black in the upper left. 

Text, Like a big city sparkling with lights, our galaxy, the Milky Way, glitters with the light from billions of stars. 

A blue spiral galaxy. 

Text, We live in the outskirts of this immense cosmic city. 

Our star, the Sun, is our "porch light." 

Galaxies in black space. 

Text, Far in the distance are other stellar cities -- other galaxies, each shining with their own huge collection of stars. 

Some galaxies are smaller, like quaint little towns. 

Others sprawl out, each one a cosmic metropolis. 

Glowing galaxies flow by in outer space. 

Text, Everywhere we look, in every direction, these celestial cities go on and on as far as our eyes and telescopes can see. 

There are billions of other galaxies like ours -- each filled with millions, billions, or even trillions of stars -- scattered throughout our incredible universe. A Visualization of numerous galaxies as they fly past us.
