Galaxies are collections of millions, or billions of stars. The Milky Way is the galaxy in which we live, orbiting around it’s centre in a distant spiral arm. But when we look into the night sky the stars look similar in every direction we look, so how do we know where we are?
Use this investigation to take observations inside and outside of our galaxy, to compare the number of stars and think a little more about the structure of the Milky Way.
By the end of this resource you will:
- have used a robotic telescope to take observations.
- carry out an investigation to compare 2 patches of the night sky, one inside and one outside of our galaxy.
- have opened and analysed your observations in specialist software.
- have drawn conclusions from your investigation.
To complete this resource you will need:
- Access to Go Observing through your Schools’ Observatory log in.
- Access to the internet
- Access to our software
- Investigation planning and results worksheets
