Lunar eclipse - wikipedia Lunar eclipse For other uses, see Lunar eclipse ( disambiguation ). Not to be confused with Solar eclipse. Recent total lunar eclipses October 8, 2014 April 4, 2015 September 28, 2015 January 31, 2018 A lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. This can occur only when the Sun, Earth, and the Moon are aligned ( in syzygy ) exactly or very closely so, with the planet in between. Hence, a lunar eclipse can occur only on the night of a full moon. The type and length of an eclipse depend on the Moon 's position relative to its orbital nodes. During a total lunar eclipse, Earth completely blocks direct sunlight from reaching the Moon. The only light reflected from the lunar surface has been refracted by Earth 's atmosphere. This light appears reddish for the same reason that a sunset or sunrise does : the Rayleigh scattering of bluer light. Due to this reddish color, a totally eclipsed Moon is sometimes called a blood moon. Unlike a solar eclipse, which can be viewed only from a certain relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse lasts a few hours, whereas a total solar eclipse lasts only a few minutes as viewed from any given place, due to the smaller size of the Moon 's shadow. Also unlike solar eclipses, lunar eclipses are safe to view without any eye protection or special precautions, as they are dimmer than the full Moon. For the date of the next eclipse, see the section Recent and forthcoming lunar eclipses.

Within the central umbra shadow, the moon is totally shielded from direct illumination by the Sun. In contrast, within the penumbra shadow, only a portion of Sunlight is blocked. A total penumbral lunar eclipse dims the moon in direct proportion to the area of the Sun 's disk blocked by the Earth. This comparison shows the southern shadow penumbral lunar eclipse of January 1999 ( left ) to the moon outside of the shadow ( right ) demonstrates this subtle dimming. The shadow of the Earth can be divided into two distinctive parts : the umbra and penumbra. Within the umbra, there is no direct solar radiation. However, as a result of the Sun 's large angular size, solar illumination is only partially blocked in the outer portion of the Earth 's shadow, which is given the name penumbra. A penumbral eclipse occurs when the moon passes through the Earth 's penumbra. The penumbra causes a subtle darkening of the moon 's surface. A special type of penumbral eclipse is a total penumbral eclipse, during which the Moon lies exclusively within the Earth 's penumbra. Total penumbral eclipses are rare, and when these occur, that portion of the moon which is closest to the umbra can appear somewhat darker than the rest of the moon. A partial lunar eclipse occurs when only a portion of the moon enters the umbra. When the moon travels completely into the Earth 's umbra, one observes a total lunar eclipse. The moon 's speed through the shadow is about one kilometer per second ( 2,300 mph ), and totality may last up to nearly 107 minutes. Nevertheless, the total time between the moon 's first and last contact with the shadow is much longer and could last up to four hours. The relative distance of the moon from the Earth at the time of an eclipse can affect the eclipse 's duration. In particular, when the moon is near its apogee, the farthest point from the Earth in its orbit, its orbital speed is the slowest. The diameter of the umbra does not decrease appreciably within the changes in the orbital distance of the moon. Thus, a totally eclipsed moon occurring near apogee will lengthen the duration of totality. A central lunar eclipse is a total lunar eclipse during which the moon passes through the centre of the Earth 's shadow. These are relatively rare. Selenelion October 2014 lunar eclipse viewed from Minneapolis, with a partially eclipsed Moon still up after sunrise, seen as sunlight on the tree on the right. A selenelion or selenehelion occurs when both the Sun and the eclipsed Moon can be observed at the same time. This can happen only just before sunset or just after sunrise, and both bodies will appear just above the horizon at nearly opposite points in the sky. This arrangement has led to the phenomenon being referred to as a horizontal eclipse. There are typically a number of high ridges undergoing sunrise or sunset that can see it. Although the moon is in the Earth 's umbra, the Sun and the eclipsed Moon can both be seen at the same time because the refraction of light through the Earth 's atmosphere causes each of them to appear higher in the sky than their true geometric position. Timing As viewed from Earth, the Earth 's shadow can be imagined as two concentric circles. As the diagram illustrates, the type of lunar eclipse is defined by the path taken by the Moon as it passes through Earth 's shadow. If the moon passes through the outer circle but does not reach the inner circle, it is a penumbral eclipse ; if only a portion of the moon passes through the inner circle, it is a partial eclipse ; and if entire Moon passes through the inner circle at some point, it is a total eclipse. Contact points relative to the Earth 's umbral and penumbral shadows, here with the Moon near is descending node The timing of total lunar eclipses are determined by its contacts : P1 ( First contact ) : Beginning of the penumbral eclipse. Earth 's penumbra touches the Moon 's outer limb. U1 ( Second contact ) : Beginning of the partial eclipse. Earth 's umbra touches the Moon 's outer limb. U2 ( Third contact ) : Beginning of the total eclipse. The Moon 's surface is entirely within Earth 's umbra. Greatest eclipse : The peak stage of the total eclipse. The Moon is at its closest to the center of Earth 's umbra. U3 ( Fourth contact ) : End of the total eclipse. The Moon 's outer limb exits Earth 's umbra. U4 ( Fifth contact ) : End of the partial eclipse. Earth 's umbra leaves the Moon 's surface. P4 ( Sixth contact ) : End of the penumbral eclipse. Earth 's penumbra no longer makes contact with the Moon. Danjon scale The following scale ( the Danjon scale ) was devised by André Danjon for rating the overall darkness of lunar eclipses : L = 0 : Very dark eclipse. Moon almost invisible, especially at mid-totality. L = 1 : Dark eclipse, gray or brownish in coloration. Details distinguishable only with difficulty. L = 2 : Deep red or rust - colored eclipse. Very dark central shadow, while outer edge of umbra is relatively bright. L = 3 : Brick - red eclipse. Umbral shadow usually has a bright or yellow rim. L = 4 : Very bright copper - red or orange eclipse. Umbral shadow is bluish and has a very bright rim. Lunar versus solar eclipse A solar eclipse occurs in the day time at new moon, when the moon is between the Earth and the sun, while a lunar eclipse occurs at night when the Earth passes between the Sun and the Moon. The moon does not completely disappear as it passes through the umbra because of the refraction of sunlight by the Earth 's atmosphere into the shadow cone. There is often confusion between a solar and lunar eclipse. While both involve interactions between the sun, Earth, and moon, they are very different in their interactions. Lunar eclipse appearance A lunar eclipse occurs in two regions, an outer penumbral shadow where the sunlight is dimmed, and an inner umbral shadow, where much dimmer sunlight only exists by refraction through the Earth 's atmosphere, leaving a red color. This can be seen in different exposures of a partial lunar eclipse, for example here with exposures of 1 / 80, 2 / 5, and 2 seconds. The moon does not completely disappear as it passes through the umbra because of the refraction of sunlight by the Earth 's atmosphere into the shadow cone ; if the Earth had no atmosphere, the Moon would be completely dark during an eclipse. The reddish coloration arises because sunlight reaching the Moon must pass through a long and dense layer of the Earth 's atmosphere, where it is scattered. Shorter wavelengths are more likely to be scattered by the air molecules and the small particles, and so by the time the light has passed through the atmosphere, the longer wavelengths dominate. This resulting light we perceive as red. This is the same effect that causes sunsets and sunrises to turn the sky a reddish color ; an alternative way of considering the problem is to realize that, as viewed from the moon, the sun would appear to be setting ( or rising ) behind the Earth. From the Moon, a lunar eclipse would show a ring of reddish - orange light surrounding a dark Earth in the sky. The amount of refracted light depends on the amount of dust or clouds in the atmosphere ; this also controls how much light is scattered. In general, the dustier the atmosphere, the more that other wavelengths of light will be removed ( compared to red light ), leaving the resulting light a deeper red color. This causes the resulting coppery - red hue of the moon to vary from one eclipse to the next. Volcanoes are notable for expelling large quantities of dust into the atmosphere, and a large eruption shortly before an eclipse can have a large effect on the resulting color. Christopher Columbus predicting the lunar eclipse. Lunar eclipse in culture Several cultures have myths related to lunar eclipses or allude to the lunar eclipse as being a good or bad omen. The Egyptians saw the eclipse as a sow swallowing the moon for a short time ; other cultures view the eclipse as the moon being swallowed by other animals, such as a jaguar in Mayan tradition, or a three legged toad in China. Some societies thought it was a demon swallowing the moon, and that they could chase it away by throwing stones and curses at it. The Greeks were ahead of their time when they said the Earth was round and used the shadow from the lunar eclipse as evidence. Some Hindus believe in the importance of bathing in the Ganges River following an eclipse because it will help to achieve salvation. Incans Similarly to the Mayans, the Incans believed that lunar eclipses occurred when a jaguar would eat the moon, which is why a blood moon looks red. The Incans also believed that once the jaguar finished eating the moon, it could come down and devour all the animals on Earth, so they would take spears and shout at the moon to keep it away. Mesopotamians The ancient Mesopotamians believed that a lunar eclipse was when the moon was being attacked by seven demons. This attack was more than just one on the moon, however, for the Mesopotamians linked what happened in the sky with what happened on the land, and because the king of Mesopotamia represented the land, the seven demons were thought to be also attacking the king. In order to prevent this attack on the king, the Mesopotamians made someone pretend to be the king so they would be attacked instead of the true king. After the lunar eclipse was over, the substitute king was made to disappear ( possibly by poisoning ). Chinese In some Chinese cultures, people would ring bells to prevent a dragon or other wild animals from biting the moon. In the nineteenth century, during a lunar eclipse, the Chinese navy fired its artillery because of this belief. During the Zhou Dynasty in the Book of Songs, the sight of a red moon engulfed in darkness was believed to foreshadow famine or disease. Blood moon See also : Blood Moon Prophecy Certain lunar eclipses have been referred to as `` blood moons '' in popular articles but this is not a scientifically - recognized term. This term has been given two separate, but overlapping, meanings. The first, and simpler, meaning relates to the reddish color a totally eclipsed Moon takes on to observers on Earth. As sunlight penetrates the atmosphere of Earth, the gaseous layer filters and refracts the rays in such a way that the green to violet wavelengths on the visible spectrum scatter more strongly than the red, thus giving the Moon a reddish cast. The second meaning of `` blood moon '' has been derived from this apparent coloration by two fundamentalist Christian pastors, Mark Blitz and John Hagee. They claimed that the 2014 -- 15 `` lunar tetrad '' of four lunar eclipses coinciding with the feasts of Passover and Tabernacles matched the `` moon turning to blood '' described in the Book of Joel of the Hebrew Bible. This tetrad was claimed to herald the Second Coming of Christ and the Rapture as described in the Book of Revelations on the date of the first of the eclipses in this sequence on April 15, 2014. Occurrence This multi-exposure sequence shows the August 2017 lunar eclipse visible from the ESO headquarters. This collage shows the transitional stages of a lunar eclipse. See also : Saros ( astronomy ) and Eclipse cycle At least two lunar eclipses and as many as five occur every year, although total lunar eclipses are significantly less common. If the date and time of an eclipse is known, the occurrences of upcoming eclipses are predictable using an eclipse cycle, like the saros.
