Eclipse Details: Lunar Eclipse Chapter index in this window Chapter index in separate window This material (including images) is . See my for fair use practices. Let's explore a little more about lunar and solar eclipses. Remember that an eclipse happens when an object passes through another object's shadow. Any shadow consists of two parts: an umbra which is the region of total shadow and the penumbra which is the outer region of partial shadow. If the Moon were to pass through the Earth's umbra, an observer on the Moon would not be able to see the Sun at all-she would observe a solar eclipse! An observer on the Earth looking at the Moon would see a total lunar eclipse. The Earth's shadow is pretty big compared to the Moon so a total lunar eclipse lasts about 1 hour 45 minutes. If the Moon only passed through the outer part of the shadow (the penumbra), then the observer on the Moon would see the Sun only partially covered up-a partial solar eclipse. The observer on the Earth would see the Moon only partially dimmed-a partial lunar eclipse.

42. SkyEye - Eclipses Learn about some of the most spectacular events in the sky eclipses. http://www.obliquity.com/skyeye/misc/eclipse.html

SkyEye Eclipses A solar eclipse occurs when the new Moon passes between the Sun and the Earth, casting a shadow on the Earth. There are three types of solar eclipses: annular partial , and total A partial solar eclipse occurs when the Sun and the Moon are not quite lined up. In this case, the Moon covers only a section of the Sun. This kind of eclipse usually goes unnoticed by most people on Earth because the sunlight is scarcely dimmed. A total solar eclipse, however, is much more spectacular. At totality, the disc of the Sun is completely obscured by the new Moon, and only the ghostly solar corona and perhaps gigantic solar flares are visible around the edges of the Moon. Those parts of the Earth experiencing totality become very dark and it is possible to see stars in the sky. An annular solar eclipse is similar to a total eclipse except that the new Moon is near apogee and its disc appears slightly smaller than that of the Sun. Thus, a bright ring or annulus of the solar disc remains at maximum eclipse, and the sky does not become dark. There are at least two and sometimes as many as five solar eclipses every year. Why don't we have a solar eclipse during every new Moon? This is because the Moon's orbit around the Earth is at an angle to the ecliptic. The new Moon usually passes above or below the Sun as seen from the Earth and thus there is no eclipse. The proper alignment for a solar eclipse occurs only a few times a year.

43. On The Nature Of Eclipses They also cast shadows, and when, in the course of their orbits, the Moon s shadow falls on the Earth, or vice versa, it is known as an eclipse. http://www.inconstantmoon.com/cyc_ecl1.htm

on the nature of eclipses The Sun is the only body in the solar system which shines with its own light. All of the others, including the Earth and Moon, reflect the Sun's light. They also cast shadows, and when, in the course of their orbits, the Moon's shadow falls on the Earth, or vice versa, it is known as an eclipse. There are two parts to these shadows. The umbra is a central cone of darkness which tapers away from the Earth or Moon, whilst the penumbra is an outer cone of partial shadow which diverges instead of tapering. solar eclipse The Moon's shadow cast on the Earth appears as a solar eclipse. An observer inside the circle of the penumbra will see a partial solar eclipse: the Moon shows as a bite taken out of the Sun's disc. Within the smaller, inner circle of the umbra the Sun will be entirely blotted out by the Moon. Anyone outside the the area covered by the penumbra (and therefore also the umbra) will see no eclipse at all. The shadow travels across the surface of the Earth, generally along a curved track. The zone covered by the umbra is called the path of totality, and although no more than 270km (170 miles) wide (when the Moon is directly overhead) it may be thousands of kilometers long. There is a system of terms and notations for the key stages of a solar eclipse: First Contact (P1) - The observer enters the penumbra, the start of the partial eclipse.

44. Mars Global Surveyor MOC2-187 Release Martian eclipses are therefore dark but not as spectacular as total solar In compensation, the martian eclipses are thousands of times more common, http://www.msss.com/mars_images/moc/11_1_99_phobos/

Mars Global Surveyor Mars Orbiter Camera MOC Views of Martian Solar Eclipses MGS MOC Release No. MOC2-187, 1 November 1999 (A) (B) The shadow of the martian moon, Phobos, has been captured in many recent wide angle camera views of the red planet obtained by the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC). Designed to monitor changes in weather and surface conditions, the wide angle cameras are also proving to be a good way to spot the frequent solar eclipses caused by the passage of Phobos between Mars and the Sun. The first figure (A, above), shows wide angle red (left), blue (middle), and color composite (right) views of the shadow of Phobos (elliptical feature at center of each frame) as it was cast upon western Xanthe Terra on August 26, 1999, at about 2 p.m. local time on Mars. The image covers an area about 250 kilometers (155 miles) across and is illuminated from the left. The meandering Nanedi Valles is visible in the lower right corner of the scene. Note the dark spots on three crater floorsthese appear dark in the red camera image (left) but are barely distingished in the blue image (middle), while the shadow is dark in both images. The spots on the crater floors are probably small fields of dark sand dunes. The second figure (B, above), shows three samples of MOC's global image swaths, each in this case with a shadow of Phobos visible (arrow). The first scene (left) was taken on September 1, 1999, and shows the shadow of Phobos cast upon southern Elysium Planitia. The large crater with dark markings on its floor at the lower right corner is Herschel Basin. The second scene shows the shadow of Phobos cast upon northern Lunae Planum on September 8, 1999. Kasei Valles dominates the upper right and the deep chasms of Valles Marineris dominate the lower third of the September 8 image. The picture on the right shows the shadow of Phobos near the giant volcano, Olympus Mons (upper left), on September 25, 1999. Three other major volcanoes are visible from lower-center (Arsia Mons) and right-center (Pavonis Mons) to upper-middle-right (Ascraeus Mons).

Other Pages A solar eclipse occurs when the Moon, during its monthly trip around the Earth, happens to line up exactly between the Earth and the Sun. The glory of a solar eclipse comes from the dramatic view of the Sun's corona, or outer atmosphere, which we can see only when the brilliant solar disk is blocked by the Moon. The corona is not just light shining from around the disk. It is actually the outermost layer of the solar atmosphere. Although the gas is very sparse, it is extraordinarily hot (800,000 to 3,000,000 K), even hotter than the surface of the Sun! The corona shows up as pearly white streamers, and their shape is determined by the Sun's current magnetic fields. Thus every eclipse will be unique and beautiful in its own way.

51. Eclipses Solar eclipses A solar eclipse occurs when the Moon passes directly in front of the Sun, blocking out its view over a small region on the Earth. http://www.astro.cornell.edu/academics/courses/astro201/eclipse.htm

Click here to find Fred Espenak's eclipse page at the NASA Goddard Space Flight Center. Solar Eclipses: A solar eclipse occurs when the Moon passes directly in front of the Sun , blocking out its view over a small region on the Earth. Remember that the angular diameters of the Sun and the Moon as viewed from Earth are almost identical. Lunar Eclipses: A lunar eclipse occurs when the Moon moves through the Earth's shadow, thereby blocking sunlight from falling on the Moon. In order for there to be a total eclipse, the Moon must go through the umbra of the Earth's shadow. If the Moon partly goes through the umbra, there will be a partial eclipse. If the Moon only goes through the penumbra, then the Moon's light is only slightly dimmed, and the eclipse is hardly noticeable here on Earth. The Moon's orbit is tipped by 5 degrees with respect to the Earth's orbit. Therefore, eclipses do not occur every month. Instead, there are two eclipse seasons every year, about 6 months apart. Eclipses can occur only then the Sun, Moon and Earth line up perfectly, that is, when the line of interesection of the Earth's orbit plane and the Moon's points directly at the Sun. This is called the line of nodes. Movement of the line of nodes causes the eclipse seasons to vary from one year to the next.

For other uses, see Total Eclipse This view from the International Space Station shows the shadow of the Moon cast upon the eastern Mediterranean Sea near Cyprus NASA image. An eclipse Ancient Greek noun έκλειψις ( ©kleipsis ), from verb εκλείπω ( ekle­pō ), "I cease to exist," a combination of prefix εκ- ( ek- ), from preposition εκ, εξ ( ek ex ), "out," and of verb λείπω ( le­pō ), "I am absent") is an astronomical event that occurs when one celestial object moves into the shadow of another. The term is most often used to describe either a solar eclipse , when the Moon's shadow crosses the Earth's surface, or a lunar eclipse , when the Moon moves into the shadow of Earth. However, it can also refer to such events beyond the Earth-Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its parent planet, or a moon passing into the shadow of another moon.

Eclipse Near the beginning and end of total solar eclipse, the thin slice of the Sun visible appears broken up into beads of light. These lights are called 'Baily's Beads' after the British astronomer Francis Baily who discovered them. They occur because the edge of the Moon is not smooth but jagged with mountain peaks. When just one bead is visible, the effect is often likened to a diamond ring. A solar eclipse occurs when the Moon passes in front of the Sun and obscures it totally or partially. This configuration can only exist at New Moon, when Sun, Moon and Earth are on a single line with the Moon in the middle. There are four types of solar eclipses: A partial solar eclipse occurs when the Sun is only partially overlapped by the Moon. A total solar eclipse occurs when the Moon completely obscures the Sun. This happens when the Moon is near perigee and its angular diameter as seen from Earth is identical to or slightly larger than that of the Sun. A total solar eclipse is the only opportunity to observe the Sun's corona without specialised equipment. An annular (ring-formed) eclipse occurs when the Moon's center passes in front of Sun's center while the Moon is near apogee. The Moon's angular diameter is then smaller than that of the Sun so that a ring of the Sun can still be seen around the Moon. This is similar to a penumbral eclipse.
