Explore Our Galactic Neighbourhood | The Schools' Observatory

Galaxies do not exist alone – they are part of groups. These groups can also be part of larger clusters with hundreds of thousands of galaxies. Each galaxy type has smaller versions called dwarf galaxies. Our own galaxy, the Milky Way, belongs to a group called the Local Group.

In this activity, you will map out the galaxies in the Local Group and explore our galactic neighbours!

By the end of this resource you will:

Know that galaxies exist in small groups and larger clusters
Be able to describe different types of galaxies, including dwarf galaxies
Understand the Milky Way’s place in the Universe
Have sketched the galaxies in our Local Group using a grid

To complete this resource you will need:

To watch the 'What is a galaxy' video
A copy of the worksheet
A pencil for drawing

Your challenge is to map the galaxies in the Local Group by completing a hands-on sketching activity.

Step 1:

Download the worksheet linked on this page.

Step 2:

Gather the materials you need before you begin.

Step 3:

Use the table in the worksheet to identify the type and classification of each galaxy.

Step 4:

Match each galaxy to the correct symbol using the galaxy key.

Step 5:

Locate each galaxy’s grid position and sketch its symbol in the correct place on the grid.

Step 6:

Use your completed grid to answer questions about the Local Group.

Step 7:

Discuss your findings with your group or class. What patterns did you notice?

Well done – you have explored our galactic neighbourhood just like an astronomer!
