NASA's Jet Propulsion Laboratory website contains a large library of infographics that you can download and print for free. The library contains infographics about spacecraft, exploration missions, planets, moons, the solar system, and comets. I downloaded the What is Comet Made Of? infographic that you see pictured below.

Applications for Education
If printed in color, these infographics could make a nice addition to your classroom walls. More importantly these infographics could provide a model for your students to follow as they create their own infographics about topics in space science.
