6 copies left

The sun is a fascinating object to study, and, contrary to popular opinion, it is very easy to view it safely, either by projecting its image or by using filters. Pam Spence, an experienced astronomer, explains how to observe the Sun, what you should look for and what you can learn from your observation. She also explains how to look at the Sun in visible, or white, light, as well as in other wavelengths.
