All About Eclipses An eclipse is defined as an astronomical event that occurs when one celestial object moves into the shadow of another, partially or fully obscuring it from view. An eclipse on Earth occurs when the Sun , the Earth and the moon are all in a line together. The two primary types of eclipses seen from Earth are the solar eclipse and the lunar eclipse. These two types of eclipses can then be broken down into four different types; a total eclipse, partial eclipse, annular eclipse or hybrid eclipse. The term solar eclipse describes the occurrence of when the moon travels between the Sun and the Earth, blocking the Sun’s light from the Earth in the middle of the day, and generally giving the appearance of a ring of light in the darkened sky. During a lunar eclipse, the moon moves into the shadow of the Earth during night time hours, gradually blocking the view of the moon form the Earth. Eclipses have also been known to occur on other planets as well. On Earth, there can be anywhere from four to seven eclipses of varying degrees within any given year. For more eclipse information on both lunar and solar eclipses, simply select any eclipse article, eclipse picture or other interactive eclipse feature below.

3. What Causes An Eclipse? An eclipse occurs at those times when the Moon moves into a position of direct alignment with the Sun and the Earth. There are two basic types of eclipses http://www.earthview.com/tutorial/causes.htm

What Causes an Eclipse? What Causes an Eclipse? An eclipse occurs at those times when the Moon moves into a position of direct alignment with the Sun and the Earth total lunar eclipse But the gentle beauty of a lunar eclipse pales in comparison with the truly awesome spectacle of a total solar eclipse , which occurs when the new Moon passes directly between the Sun and the Earth. In the narrow path of totality umbra corona dark disk of the Moon totally obscures the bright Sun penumbra Not all solar eclipses are total. During a partial solar eclipse , only the penumbra touches our planet. The umbra passes either just above the North Pole or just below the South Pole, completely missing the Earth. No total eclipse is visible only partial phases can be seen. A third type of solar eclipse occurs when the Moon's umbra passes across the Earth, but is not quite long enough to touch the surface; the shadow cone diminishes to a point before reaching the Earth. This effect happens when the Moon is farther out in its orbit around the Earth. The Moon appears slightly smaller and is not large enough to completely cover the Sun. When the Moon is centered over the Sun, a ring of sunlight remains visible around the edge. This type of eclipse is called an annular eclipse . (Annular comes from the Latin word meaning "ring.") Because the Sun is not completely covered by the Moon, the rare and dramatic effects of a total solar eclipse (onset of darkness and view of the corona) are not present at either annular or partial eclipses of the Sun.

(click to see more photos) Solar Eclipses for Beginners Introduction What is an eclipse of the Sun? What causes eclipses and why? How often do eclipses happen and when is the next eclipse of the Sun? You'll learn the answers to these questions and more in MrEclipse's primer on solar eclipses. Before we learn more about the eclipses of the Sun, we need to first talk about the Moon. Phases of the Moon. Phases of The Moon The Moon is a cold, rocky body about 2,160 miles (3,476 km) in diameter. It has no light of its own but shines by sunlight reflected from its surface. The Moon orbits Earth about once every 29 and a half days. As it circles our planet, the changing position of the Moon with respect to the Sun causes our natural satellite to cycle through a series of phases: New Moon > New Crescent > First Quarter > Waxing Gibbous> Full Moon > Waning Gibbous > Last Quarter > Old Crescent > New Moon (again) The phase known as New Moon can not actually be seen because the illuminated side of the Moon is then pointed away from Earth. The rest of the phases are familiar to all of us as the Moon cycles through them month after month. Did you realize that the word

5. Eclipses (Science U) An explanation of what eclipses are, with images and animations. http://www.scienceu.com/observatory/articles/eclipses/

About Eclipses Eclipses, be they solar or lunar, occur when the Earth, Sun and Moon are in a line. If the Moon is in-between the Earth and the Sun, it blocks the view of the Sun from some parts of the Earth, and this produces a solar eclipse. If, on the contrary, it is the Earth that is in-between the Sun and Moon, then the earth will block the light from the Sun before it can get to the Moon. Since moonlight is just the light the Moon reflects from the Sun, this will darken the Moon, and we get a lunar eclipse. Since the Moon goes around the Earth every 28 days, shouldn't we expect a solar eclipse about every 28 days (when the Moon is new ), and a lunar one in the same period, (when the Moon is full Well, this would be so if the orbit of the Moon were in the same plane as the orbit of the Earth around the Sun. But we know eclipses are rarer than that; and the Moon's orbit is not in the same plane. Instead, it is tilted with respect to it, and the Moon does not in general pass directly on the Earth-Sun line. Moreover, the Moon's orbit tilt varies slowly. To have an eclipse, then, it is not enough that the three bodies be in the right order; the Moon's orbit should also be at the right tilt. The behavior of the orbit of the moon (around the solar eclipse of August 11, 1999)

6. Solar Eclipses Tells how often they happen, gives a diagram that shows what the position of the earth and sun and moon are, and defines the types of solar eclipses. http://csep10.phys.utk.edu/astr161/lect/time/eclipses.html

Solar Eclipses One consequence of the Moon's orbit about the Earth is that the Moon can shadow the Sun's light as viewed from the Earth, or the Moon can pass through the shadow cast by the Earth. The former is called a solar eclipse and the later is called a lunar eclipse . The small tilt of the Moon's orbit with respect to the plane of the ecliptic and the small eccentricity of the lunar orbit make such eclipses much less common than they would be otherwise, but partial or total eclipses are actually rather frequent. Frequency of Eclipses For example there will be 18 solar eclipses from 1996-2020 for which the eclipse will be total on some part of the Earth's surface. The common perception that eclipses are infrequent is because the observation of a total eclipse from a given point on the surface of the Earth is not a common occurrence. For example, it will be two decades before the next total solar eclipse visible in North America occurs. The next total solar eclipse will be on August 11, 1999 , with the path of totality crossing the North Atlantic, Europe, the Middle East, and India. In this section we consider solar eclipses and in the next we discuss lunar eclipses. Geometry of Solar Eclipses The geometry associated with solar eclipses is illustrated in the following figure (which, like most figures in this and the next section, is illustrative and not to scale).

Eclipses depend on the moon's revolution around Earth. The moon's orbit is tilted with respect to Earth's orbit. So the moon rarely goes directly between Earth and the Sun or directly behind Earth. When the moon does move into one of these positions, an eclipse occurs. This simulation allows the student to control the position of the Earth, Sun and moon while viewing the scene from a number of different angles and perspectives to fully understand the concepts being taught.

A great event for beginners to observe Total and Partial Eclipses A lunar eclipse A lunar eclipse may be partial or total. A partial lunar eclipse occurs when the Moon skirts into the Earth's penumbral shadow. When the Moon is fully immersed in the umbra a total lunar eclipse occurs. During a lunar eclipse, the Earth passes between the Sun and the Moon, blocking the Sun’s light. We see the Earth’s shadow creep across the surface of the Moon. Lunar eclipses are not as spectacular as Solar eclipses, when day turns to night. However, they last for much longer, and can be seen from any part of the Earth’s surface where the Moon is above the horizon. They require no equipment to view, and are perfect events for beginners to observe.

Search Activities Weighing In Age Is Relative Planetary Icosahedrons Teachers Lesson Activities Student Resources Using Views of the Solar System Text Add A Search Box To Your Pages Educator's Guide to Eclipses Courtesy of the Jet Propulsion Laboratory Astronomical Alignments Eclipses have long been a source of mystery and spectacle. These events were viewed with fear and dread in the past and, even today, still thrill. There is a lot of special vocabulary involved in eclipses but there is a way to keep from being confused. The eclipse is named for the object that is being eclipsed, or obscured. In a solar eclipse you observe the Sun (using only safe methods, of course). You will see the Sun with a piece apparently cut out of it. In a lunar eclipse you observe the Moon. A portion of its surface will be obscured. Another way to avoid confusion is to consider the time at which you will be viewing the eclipse. Because of the geometry described below, you can only view a solar eclipse when the Sun is up. You view lunar eclipses when the Moon is up. Eclipses occur when the Sun, Earth and Moon line up. They are rare because the Moon usually passes above or below the imaginary line connecting Earth and the Sun. In a solar eclipse the Moon passes directly in front of the Sun. This can only happen when the phase of the Moon is "new." That occurs because, for Earth-based observers, the far side of the Moon is illuminated while the side facing Earth is in darkness. The Moon, like any sphere, casts a shadow. A solar eclipse occurs when that shadow sweeps across Earth. The black cone is called the

Confessions of a Coronaphile T otal solar Eclipses are a bigger part of my life than I'd like to admit (a touch of mindless obsession lurks nearby.) But for those who have witnessed this most spectacular of natural events, no words are capable of expressing the awe, the goose bumps, the thrill of the chase, the indelible memories wrought by one of these beauties. By the most unlikely odds, earth's moon is nearly the same angular size as the sun, when they are viewed from the surfacehalf a degree (it varies only a few percent during the year.) This permits the moon's orb, when it's path crosses the sun's, to just barely block out the intense light from the sun completely, fitting the solar disk just inside the moon's craggier one. When that happens, at least if you're lucky to be within the very narrow path the moon's shadow traces during the next few hours (or less), you will witness the day become near-night, like the deepest twilight. Sunset colors bathe the full horizon, while a gaping black hole gazes down at you from the inky sky, eye-like and surreal, surrounded by the solar

Lunar Eclipses This image explains how the Earth's shadow causes a lunar eclipse. Notice the difference between the umbra and the penumbra. Click on image for full size ( 17K JPG Windows Original Lunar eclipses are special events that only occur when certain conditions are met. First of all, the Moon must be in full phase . Secondly, the Sun Earth and Moon must be in a perfectly straight line. If both of these are met, then the Earth's shadow can block the Sun's light from hitting the Moon. There are three types of lunar eclipses. Which one we will see depends on the alignment of the three celestial objects. But first, you need to know that the Earth's shadow is broken up into two parts. The umbra is the darker part of the shadow, where no part of the Sun can been seen. The penumbra is lighter than the umbra, because part of the Sun can be seen. So, when part of the Moon passes through the umbra, this is called a partial eclipse. When all of the Moon passes through the umbra, this is called a total eclipse. Finally, when the Moon only passes through the penumbra, this is called a penumbral eclipse. Now that you know all about eclipses, you can step outside and enjoy the show! Remember that lunar eclipses are not dangerous to the eye, so you don't need protection to watch. Just find a nice, cozy spot and enjoy!

A lunar eclipse occurs when the moon passes through the shadow of the earth. A lunar eclipse can last up to an hour and a half. During a lunar eclipse the moon may turn a reddish color. It is not dangerous at all to look at a lunar eclipse because the moon does not make its own light. Animation by Stephen Gray using photos © James Funkhouser Photograph © James Funkhouser A Solar Eclipse occurs when the moon goes in front of the sun and blocks most of the sun's light from the earth. During a total eclipse all you can see from earth is a ring of light around the moon which is part of the sun the moon did not cover. It is dangerous to look at a solar eclipse directly, even if you have sun glasses or smoked glass. It is better to view solar eclipses through a pin hole projector.
