Sponsored by Gettysburg College and the National Science Foundation, Project CLEA, Contemporary Laboratory Experiences in Astronomy, develops laboratory exercises that illustrate modern astronomical techniques using digital data and color images.

These exercises are suitable for high school and college classes at all levels, but come with defaults set for use in introductory astronomy classes for non-science majors.

Each CLEA laboratory exercise includes a dedicated computer program, a student manual, and a technical guide for the instructor.

The technical guides describe file formats, user-settable options, and algorithms used in the programs. The most advanced CLEA labs run under Windows on PCs, or under Windows emulation on Macintosh computers.
