Stretching across the dark night sky, not easily visible when the Moon is in the sky, is a faint irregular glowing strip of light. For thousands of years peoples of various cultures tried to explain what they saw, sometimes using stories. Here are some examples:


The seventh Princess of Heaven fell in love with a poor herdsman and ran away to marry him. When her mother sent soldiers to bring her home, the herdsman chased them away. Seeing her daughter’s husband running, the mother dropped a silver pin to make a silver stream to separate the lovers forever. Eventually, her father allowed her to have an annual reunion with her husband — black birds escorted her across the stream. The Milky Way is that silver stream. The young lovers are the stars Vega and Altair on either side of it.


When the world was created, the people gathered around Black God to place stars in the sky. Coyote was frustrated by how long it was taking. He threw the bag of stars over his head, forming the Milky Way.


The goddess Isis spread large quantities of wheat across the sky. We see this bounty as the Milky Way.

The Milky Way is made of the ashes of campfires.


The Milky Way is a long, blue, cloud-eating shark.


The Milky Way is along the circular path where the Sun once moved across the sky. It looks different than the rest of the sky because the Sun scorched it.

Activity 1

Show students a picture of the Milky Way. Read several of the selections above. Tell them to work in groups to make up a story and picture that explains how someone living thousands of years ago in their location might have explained it. When the pictures are done, have each group present its report. For a link to Social Studies, have them choose a civilization to research to discover what important elements of their culture are reflected in these stories.


Galileo, the first person to look at the sky with a telescope, discovered that the Milky Way is actually made up of countless faint stars. Other astronomers discovered it also had many star clusters and nebulae (clouds of gas and dust). In the 20th century, astronomers put together clues from many types of observations to deduce that we live at the edge of a spiral arm in the Milky Way galaxy. Because we are in the arm, we look at the rest of the galaxy edge-on and don’t easily see its structure. If we could take a picture of the Milky Way from a vast distance, we would see it as a majestic cosmic pinwheel. The Sun is just one of hundreds of billions of stars in the Milky Way galaxy. The stars in the arms are young, and many of them are hot and blue. The stars in the core and between the spiral arms are mostly older and redder.

Activity 2

Examine color pictures of spiral galaxies. Using them as examples, take yellow and red fluorescent poster paint to make a nucleus-shape in the center of a piece of black paper. Add blue spiral arms swirling out from the center. Within the arms, glue small pieces of cotton balls to indicate the gaseous nebulae. Add a flag attached to a toothpick saying “You are here” to indicate the Sun’s position about two-thirds of the way from the center, on the edge of a spiral arm.
