A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partially obscuring Earth's view of the Sun.

Solar eclipse (not to scale)
As noted above, the images that we show in discussing eclipses are illustrative but not drawn to scale.
The longest solar eclipses occur when the Earth is at aphelion (farthest from the Sun, making the solar disc smaller) and the Moon is at perigee (closest to the Earth, making the Moons apparent diameter larger).
A spectacular total solar eclipse over the ancient statues of Easter Island is set to occur on 11 July, where those lucky enough to have made it to the Pacific will witness the last total eclipse to occur until November 2012.
where n is an integer, and solar eclipses occur when n (mod 223) is one of 0, 6, 12, 18, 24, 30, 36, 42, 47, 53, 59, 65, 71, 77, 83, 89, 88, 94, 100, 106, 112, 118, 124, 130, 135, 141, 147, 153, 159, 165, 171, 177, 182, 188, 194, 200, 206, 212, ...

During a solar eclipse, the moon comes between the sun and Earth so that all or part of the sun's light is blocked from Earth.
Martian Solar Eclipses
The shadow of the Martian moon, Phobos, is captured here by the Mars Global Surveyor wide angle camera. Frequent solar eclipses are caused by the passage of Phobos between Mars and the Sun.

Partial solar eclipse, 3 October 2005. The picture was taken through a solar filter.
Solar Eclipses
A total solar eclipse can occur only when the moon is in its new phase. At this time the moon is between the sun and the earth and cannot be seen until it moves across the sun's disk.

a phenomenon that occurs when the Earth passes into the shadow of the Moon. A total solar eclipse occurs when the Moon is close enough to completely block the Sun's light.

Solar eclipses can only occur within a few days of the New Moon, but they do not happen at every New Moon. This is due to the 5.1 degree tilt of the Moon's orbit around the Earth compared to the Earth's orbit around the Sun.
Solar Eclipse
A phenomenon in which the Moon's disk passes in front of the Sun, blocking sunlight. A total eclipse occurs when the Moon completely obscures the Sun's disk, leaving only the solar corona visible.
Solar eclipses occur when the Moon, traveling in it's orbit around the Earth, comes directly between the Earth and the Sun.
Solar eclipses are relatively brief events that can only be viewed in totality along a relatively narrow track.

April 24 Penumbral Lunar Eclipse
This penumbral lunar eclipse follows the April 8 solar eclipse by a fortnight -- the shortest possible period between a solar and a lunar eclipse.
August 21 - Total Solar Eclipse. This is a rare, once-in-a-lifetime event for viewers in the United States. The last total solar eclipse visible in the United States occurred in 1979 and the next one will not take place until 2024.
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 solar eclipse occurs during a new moon, when the moon is directly between Earth and the sun, as per the illustration on the left, which is not to scale. When this happens, the moon blocks the sun's light from reaching Earth in two main ways.
A Solar eclipse (see Eclipse, Solar) in which the Solar disk is never completely covered but is seen as an annulus or ring at maximum eclipse. An annular eclipse occurs when the apparent disk of the Moon is smaller than that of the Sun. [S92] ...
A solar eclipse happens when the moon blocks our view of the sun.
A solar flare is a magnetic storm on the sun, which appears to be a very bright spot, and a gaseous surface eruption.
1991 Solar Eclipse
This image shows the total solar eclipse of July 11, 1991 as seen from Baja California. It is a digital mosaic derived from five individual photographs, each exposed correctly for a different radius in the solar corona.

Since total solar eclipse is a very stunning experience, people will travel around the globe to watch it. The following photos will give you some flavors of how a total eclipse is.

This is called a solar eclipse; if the alignment is slighly imperfect then the Moon covers only part of the Sun's disk and the event is called a partial eclipse.
You were probably told in elementary school "Don't ever look at a solar eclipse - you'll go blind!" or something like that. That's not entirely true, though you have a pretty good opportunity to really screw up your eyes if you are really stupid.
Total solar eclipses occur when the moon's umbra reaches the earth. The diameter of the umbra is never greater than 268.
In 1868, during a solar eclipse, the French astronomer Pierre Janssen pointed a spectrometer at the suddenly visible corona and found a bright yellow line that he took to represent sodium.

[10] Section #8b, about using a total solar eclipse to estimate the distance of the Moon, includes a map of the eclipse of August 11, 1999. The path of totality across the Black Sea is shown, as are samples of the region of totality at selected times.
Just as totality begins during a solar eclipse a small portion of the Suns photosphere can peak out from behind the moon through a valley at the edge of the lunar disk. It is not visible during every solar eclipse.

K. A lunar eclipse is the opposite of a solar eclipse. Instead of the moon moving between the earth and the sun (a solar eclipse) casting its shadow on earth, the earth comes between the sun and the moon casting its shadow over the moon.
