What can we learn about the stars and planets from their colors?
To answer this question requires a fundamental understanding of
why we see color. Through a series of activities, students deepen
their understanding. They "travel" to an imaginary planet circling a
red sun, and experiment with color filters and diffraction gratings.
Related classroom activities include observing spectra, making secret
messages that can be decoded only with color filters, and then using the
same filters to view nebulae and planets.
