Are There Solar Eclipses on the Moon?
Total solar eclipse: the Sun a black circle framed by an ethereal corona. Dark enough to see stars, and for birds to go to sleep – yet an eerie darkness unlike night. The Sun can also be eclipsed on other Solar System planets as long as they have moons. But what would we see from our own Moon?
*Solar eclipse coming in a few days*
A reminder that there's a lot of useful information, links, and interesting things about solar eclipses on this forum thread: http://forums.bellaonline.com/ubbthreads.php/topics/918130/American_Eclipse_August_21st#Post918130
