The Hidden Lives of Galaxies - Identifying Galaxies

Activity #2 — Identifying Galaxies

Objectives:

  1. Using the "Hidden Lives of Galaxies" poster, the student will gain knowledge of galaxy morphology.
  2. Student will observe different images of galaxies from the Hubble Space Telescope deep survey image.
  3. Student will be able to identify the basic types of galaxies (spiral, elliptical, barred spiral, peculiar, or irregular) from the Hubble Space Telescope deep survey image.

Directions:

  1. List the five types of galaxies shown on the "The Hidden Lives of Galaxies" poster and write a brief description of each. (see Transparency #1: Types of Galaxies, http://imagine.gsfc.nasa.gov/educators/galaxies/transparencies/)
