Scenes from COSI's "Invisible Astronomy" interactive videoconference program for grades 7-12.

Here, Ohio State University astronomy professor Dr. David Ennis takes two classrooms of high school students, including a Canadian classroom, through a lesson on how astronomers use space telescopes to make observations in infrared light, and what astronomical objects this light reveals. Dr. Ennis began studying astronomy in 1975.

Jessica Teng, COSI's Manager of Interactive Videoconference Programs, facilitates.

This program and the related kit have been partially funded by the Smithsonian Astrophysical Observatory Chandra Grant.

COSI is Columbus, Ohio's dynamic Center of Science and Industry. For more information, please visit
