      <string language="en">This activity aims to introduce to students the concept of varying galactic 
morphologies. Students will look in detail at images of numerous galaxies 
derived from the ‘Faulkes telescopes’ and they will attempt to classify 
them according to their own notion and then according to the Hubble 
Classification Scheme. Moreover, the class will try to investigate the origin 
of the shapes of the galaxies that stem from galaxy interactions using the 
“Galaxy Crash’ simulation.
