• Lunar And Solar Eclipses .
• Lunar and Solar Eclipses.
• Perhaps the most spectacular astronomical events that one can observe without a telescope, lunar and solar eclipses were considered omens of great fortune or complete disaster in ancient times. We now know that the occurrence of eclipses is a consequence of the orbits of the Earth and Moon with respect to the Sun.
• Similarly, the Moon can come between the Sun and the Earth during the day, temporarily blocking the Sun from view: these events are called solar eclipses. ...
• The relative motions of the Earth and the Moon cause solar eclipses to be visible only within a strip of a few degrees in latitude, and total obscuration lasts no more than about seven minutes. ... Because the shadow cast by the Earth is quite a bit larger than the Moon, lunar eclipses are more common than solar eclipses, and totality can last for about an hour. Nonetheless, the beauty of such events entices both professional and amateur astronomers alike to chase them all around the globe!

• TB: What about predicting eclipses. ...
• Dirk: Newton's discovery of the formula governing gravity has made it easier and more precise but even thousands of years ago people had found a way of predicting eclipses by noticing patterns. ... They must have kept detailed records and have had a good calendar system because total eclipses at any given place occur once in a human life-time or even less frequently. The Chinese and others discovered patterns and were able to predict eclipses without knowing the causes. They are said to have spent a great deal of effort on this because of their superstitions about the significance of eclipses, which we now know to be groundless. Also, because eclipses are relatively rare but occured at precisely known dates, ancient records of them help us to date other events in early history. ...

• It will be a rare hybrid solar eclipse aka total/annular eclipse that, because of the virtually identical apparent sizes of the sun and moon during this solar eclipse and ALL hybrid solar eclipses, combines a brief total solar eclipse in the central portion of the eclipse path with an annular eclipse at the eastern and western extremities of the eclipse path. ...

The archaeological record and other anthropological evidence make it abundantly clear that the readily perceivable cosmic religious symbolism that is spectacularly manifested in the heavens during total, annular, and partial solar eclipses played a significant role in the religious beliefs and practices of most ancient cultures including, but by no means limited to, those of ancient Egypt and other ancient Mesopotamian civilizations such as Babylonia, Assyria, and Persia, many aboriginal cultures of the ancient Americas such as the Pre-Columbian civilizations of the Mayans and Aztecs of Mesoamerica, the Moche ( Mochica ) and Nazca cultures of Peru, and the Southern Cult ( Moundbuilders Indians ), the Hohokam Indians of the American SouthWest, the Tlingit, the Haida and other Pacific NorthWest Coast Indians, and even the Inuit in the far North above the Arctic circle in the "Land of the Midnight Sun". ...

• That we get total solar eclipses at all is a bit of good luck. ...
• Were the Moon to be smaller, or the Sun closer to the Earth, there would be no total solar eclipses. On the other hand, were the Moon a bit bigger, the shadow it casts on the Earth during solar eclipses would be larger, and it would be easier to be in the right place to observe them. ...
• Lunar Eclipses.
• As explained above, lunar eclipses do not occur every month because of the inclination of the Moon's orbit. ...

Now that orbiting instruments have made it possible to produce artificial eclipses with some ease, the scientific importance of natural eclipses is not quite as great. However, the esthetic aspects of solar eclipses still make them one of the most striking and exciting of astronomical events. ...
