Interacting Galaxies Arp 147 lithograph with in Search of...Peculiar Galaxies DLESE Reviewed Collection
This lithograph contains a Hubble Space Telescope image of galaxies that appear to form the number 10. The text describes the image and provides a brief explanation of why astronomer Halton Arp compiled his catalogue of odd-looking galaxies in the 1960s. The accompanying classroom activity In Search of ? Peculiar Galaxies is a curriculum support tool designed for use as an introductory inquiry activity. During the classroom activity, students use the images and text on this lithograph to generate questions about galaxy interactions. They will conduct research to answer their questions, and determine how Arp?s collection of peculiar galaxies compiled in the 1960?s contributed to today?s understanding of galaxy interactions. Students will create a presentation to demonstrate their understanding of the material, providing supporting evidence from their research.
