Study Activity

  • Planetarium Program:

    If you can, use your planetarium to view Earth from Space. In Sky Safari, chose on of the planets and then the "orbit" option, then maneuvre to see Earth, select it and fly to it with "Orbit". In Starry Night, use the Explorations option to choose Earth.

    Once you have located Earth in your screen, use the planetarium conrols to explore the surface, and note how sunlight affects the poles at this time of year. (If you are doing this exercise around Thanksgiving, the northern hemisphere is approaching midwinter, so the north pole will be in darkness, and the south pole -- Antarctica -- will be in sunlight, regardless of the time of day.)

  • Optional Website Viewing the earth as one of several planets with similar characteristics offers us a new perspective. The Univeristy of Washington's astronomy department offers courses on planetary atmospheres, planetary surfaces, and the origin of the solar system. Take a look at the topics discussed for these courses.
