But – although it’s theoretically visible to the eye under ideal conditions – you’ll be unlikely to spot the planet Uranus with the eye alone use your binoculars for this one, or a small telescope. You’ll have no trouble seeing Mars, even in the glare of the waxing crescent moon. Then let Mars help you find a much fainter planet, distant Uranus.

This review also presents a dozen suggestions for observing projects, many of which can be directly taken for individual study, for classroom projects, or for professional research.On February 9, 10 and 11, 2019, use the moon to find the red planet Mars, which still shines as brightly as a 1st-magnitude star, or one of the brightest stars in our sky. These model results can then be applied a wide variety of problems arising in history, astronomy, archeology, meteorological optics, and archeoastronomy. These formulas can then be combined as appropriate to create mathematical models for the visibility of the source under the conditions of interest. Each of these disciplines contribute specialized mathematical formulations which quantify the many processes that affect light as it leaves a source, traverses the atmosphere, and is detected by the human eye. Celestial visibility is a young discipline in the sense that the number of interesting applications with simple solutions outnumber the solved problems it is a broad interdisciplinary field that involves work with astronomy, meteorology, optics, physics, physiology, history, and archeology.
The results of such studies have more relevance to non-scientists than does any other area of astronomy. This study is based on what is seen by ordinary humans, either in their everyday lives or at times of historical events. On the contrary, unlike what stated by another popular and controversial theory (the so-called Cygnus-Giza Correlation), we have found no coincidence between the mutual positions of the three pyramids and those of the three stars of the short arm of the asterism of Northern Cross, in the Cygnus constellation.Ĭelestial visibility is the study of the limits of observability of objects in the sky, with application to deducing the truth about historical events or to the derivation of astronomical information of modern utility. These statistical analyses have been performed by means of Monte Carlo simulations and have been coupled with previous astronomical/astrophysical tests of the presumed correlation, finding that the coincidence does not seem to be fortuitous and that it is compatible with the naked-eye astrometry and photometry of the Orion Belt stars. In the present paper, this apparent coincidence has been subjected to some statistical verifications, in order to assess the probability that the correlation between stars and pyramids, both in relative position and in luminosity/height, can be merely due to the case. In particular, according to a popular and controversial hypothesis (the so-called Orion Correlation Theory), a perfect coincidence would exist between the mutual positions of the three stars of the Orion Belt and those of the main Giza pyramids. Since long time various qualitative speculations have been proposed about the link between the three major Giza pyramids and the stars.
