Go to NASA's Astronomy Picture of the Day web page (http://antwrp.gsfc.nasa.gov/apod/astropix.html)
and explore the images there by browsing the Archives or using the
Search function. Find at least 3 images that relate to a topic you have
found interesting in this course. In a 2-3 paragraph essay, discuss how
these images (and possibly their descriptions) have helped to make the
topic more interesting or understandable to you.
