The night sky is filled with wonders and sights of incomparalble beauty that can only be appreciated far from city lights. Located at the base of the Chiricahua Mountains in Southeast Arizona, Bifrost Astronomical Observatory experiences some of the darkest skies in the USA. To see the constellations and Milky Way from such a remote location is a delight that few people ever have the opportunity to enjoy. This Website offers a forum to share images from Bifrost as well as information about the ever changing motions of the Sun, Moon and planets. May it inspire you to venture outside some evening and enjoy the heavens for yourself. Carpe noctem! (Seize the night!)
