In Astronomy with Skynet: Our Place In Space! students learn how to use robotic telescopes to observe planets, moons, asteroids, binary and variable stars, supernovae, star-forming regions, star clusters, and galaxies. Most of the labs require access to Skynet and Afterglow, resources provided by Dan Reichart at the University of North Carolina-Chapel Hill. Skynet is a network of robotic telescopes across the world that can be controlled over the Internet, serving professional astronomers, students, and the general public. For some of the labs, students take photos using telescopes on the Skynet system and then analyze them using programs such as Afterglow.

The WebAssign content for these labs includes a complete lab manual with instructions and corresponding questions for completing the lab assignment. Students enter their own data and grading for subsequent calculations are based on this initial data. This course contains eight interactive lab lessons on the topics listed below.
