Play the Game!


Greetings, Space Sleuth!

We're joining our new friends Epo and Alkina to determine if the galaxy in which we live is active; if it is, we could all be in great and inescapable danger!

First, you will lean about the different shapes that galaxies take. Next you will learn about what it means for a galaxy to be active, and how astronomers tell if galaxies are active by examining their images and spectra. Then you will move on to observing some distant galaxies and making some classifications of your own. Finally, you will determine if our own galaxy is active.

This one has really got me worried space sleuth, we haven't a moment to lose!
