Most exoplanets are found through indirect methods: measuring the dimming of a star that happens to have a planet pass in front of it, called the transit method, or monitoring the spectrum of a star for the tell-tale signs of a planet pulling on its star and causing its light to subtly Doppler shift. Space telescopes have found thousands of planets by observing “transits,” the slight dimming of light from a star when its tiny planet passes between it and our telescopes. Other detection methods include gravitational lensing, the so-called “wobble method.”---------------------------------------Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

students are engaged in reflecting on whether plate tectonics is a general theory of planetary organization and evolution. Students use topographic, magnetic, spectral, and other data from NASA and ESA missions to determine whether "Earth-style" plate tectonics is functional on planets and moons elsewhere in the solar system. Students are engaged in a data-rich environment from which they must formulate and test multiple hypotheses. Throughout the process, students are engaged in small groups to identify what they need to learn to answer their questions, what resources are available to them, how best to report their findings, and how they can assess the amount of learning that is taking place.

This sample syllabus for a course on planets, exoplanets, and SETI (using the OpenStax Astronomy textbook) may help beginning instructors think through what sorts of things they might want to put on a syllabus. It can also provide guidance on how to select key sections of the textbook for a course that doesn’t have time to cover everything.

This activity includes twelve monthly star charts to identify the stars that are visible in the night sky and that are known to have planets around them. The star maps can be used to find constellations and identify stars with extrasolar planets. (Northern Hemisphere only, naked eye)
