One of the coincidences of living on Earth at the present time is that the two most prominent astronomical objects, the Sun and the Moon , have nearly the same apparent size in the sky. As a result, the Moon, as seen from Earth, can appear to cover the Sun, producing one of the most impressive events in nature. Figure 1: Solar Eclipse. Notice the dark umbra and the lighter penumbra. Four points in the shadow are labeled with numbers. In b you see what the Sun and Moon would look like in the sky at the four labeled points.

A lunar eclipse occurs when the Moon moves into the Earth's shadow. A lunar eclipse can occur only on the night of a full moon. The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit. 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 only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly 2 hours, while a total solar eclipse lasts only up to a few minutes at 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. Earth's shadow can be divided into two distinctive parts: the umbra and penumbra. Earth totally occludes direct solar radiation within the umbra, the central region of the shadow. However, since the Sun's diameter appears about one-quarter of Earth's in the lunar sky , the planet only partially blocks direct sunlight within the penumbra, the outer portion of the shadow.

A penumbral lunar eclipse occurs when the Moon passes through Earth's penumbra. Total penumbral eclipses are rare, and when these occur, the portion of the Moon closest to the umbra may appear slightly darker than the rest of the lunar disk. A partial lunar eclipse occurs when only a portion of the Moon enters Earth's umbra, while a total lunar eclipse occurs when the entire Moon enters the planet's umbra.

The Moon's average orbital speed is about 1. Nevertheless, the total time between the first and the last contacts of the Moon's limb with Earth's shadow is much longer and could last up to four hours. The relative distance of the Moon from Earth at the time of an eclipse can affect the eclipse's duration. In particular, when the Moon is near apogee , the farthest point from Earth in its orbit , its orbital speed is the slowest. The diameter of Earth's umbra does not decrease appreciably within the changes in the Moon's orbital distance.

Thus, the concurrence of a totally eclipsed Moon 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 Earth's shadow, contacting the antisolar point.

This type of lunar eclipse is relatively rare. A selenelion or selenehelion occurs when both the Sun and an eclipsed Moon can be observed at the same time. This can occur only just before sunset or just after sunrise , when both bodies will appear just above the horizon at nearly opposite points in the sky. This arrangement has led to the phenomenon being also called a horizontal eclipse.

Typically, a number of high ridges undergoing sunrise or sunset can view it. Although the Moon is in Earth's umbra, both the Sun and an eclipsed Moon can be simultaneously seen because atmospheric refraction causes each body to appear higher in the sky than their true geometric positions. The timing of total lunar eclipses are determined by its contacts: [5].

There is often confusion between a solar eclipse and a lunar eclipse. While both involve interactions between the Sun, Earth, and the Moon, they are very different in their interactions. The Moon does not completely darken as it passes through the umbra because of the refraction of sunlight by Earth's atmosphere into the shadow cone; if Earth had no atmosphere, the Moon would be completely dark during the eclipse. Shorter wavelengths are more likely to be scattered by the air molecules and small particles ; thus, the longer wavelengths predominate by the time the light rays have penetrated the atmosphere.

Human vision perceives this resulting light as red. This is the same effect that causes sunsets and sunrises to turn the sky a reddish color. An alternative way of conceiving this scenario is to realize that, as viewed from the Moon, the Sun would appear to be setting or rising behind Earth.

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. 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.

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. 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. In some Chinese cultures, people would ring bells to prevent a dragon or other wild animals from biting the Moon. Certain lunar eclipses have been referred to as "blood moons" in popular articles but this is not a scientifically-recognized term. The first, and simpler, meaning relates to the reddish color a totally eclipsed Moon takes on to observers on Earth.

The second meaning of "blood moon" has been derived from this apparent coloration by two fundamentalist Christian pastors, Mark Blitz and John Hagee. 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.

Eclipses occur only during an eclipse season , when the Sun appears to pass near either node of the Moon's orbit. From Wikipedia, the free encyclopedia. When the Moon moves into the Earth's shadow.

Lunar and Solar Eclipses

Lunar eclipses are some of the most easy-to-watch astronomical events. All you need to see them are clear skies and a pair of eyes. Anyone on the night-side of the Earth at the time of the eclipse can see it. Viewing a lunar eclipse, whether it is a partial , penumbral or total eclipse of the Moon, requires little effort.

You could be forgiven for thinking that America is suddenly experiencing lots of eclipses, but what will happen in the early hours of January 31 will be nothing like August's total solar eclipse in the U. While that event lasted just a few minutes and had to be viewed mostly through special safety glasses, the total lunar eclipse happening on Wednesday will last for hours, and be completely safe to watch. A supermoon is when our satellite is slightly closer to Earth than usual in its orbit, which results in a slightly larger and brighter moon — about 14 percent larger.

The first thing to remember about observing an eclipse is safety. A solar eclipse is potentially dangerous, however, because viewing a solar eclipse involves looking at the Sun, which can damage your eyesight. A solar eclipse can be viewed safely with the naked eye only during the few brief seconds or minutes of a total solar eclipse , when the Sun itself is completely obscured by the Moon. Partial eclipses , annular eclipses , and the partial phases of total solar eclipses are never safe to watch without taking special precautions.

Lunar Eclipse 2020 Guide: When, Where & How to See Them

Find out everything you wanted to know about partial and total solar and lunar eclipses, including when to see them in the UK. Watch more in this film series. An eclipse can be due either to a dark body coming between us and a light emitter, so that we can no longer see the source, or it can be a body coming between a light source and the body that the light is illuminating, so that we no longer see the illuminated body. An eclipse of the Sun occurs when the Moon comes directly between the Sun and the Earth so that the Earth lies in the shadow of the Moon. Because the Moon is much smaller than the Earth its shadow only covers a small part of the Earth's surface and a solar eclipse can only be seen from a restricted area. A total solar eclipse can be viewed from the darkest part of the shadow its umbra and areas covered by partial shade its penumbra witness a partial eclipse. When the Moon is not at its closest to the Earth its apparent diameter is less than that of the Sun and even where the Moon's disk obscures the Sun centrally, the outer ring of the Sun's disk is still visible. This is called an annular eclipse. An eclipse of the Moon occurs when the Earth lies directly between the Sun and the Moon and the Moon lies in the shadow of the Earth. During a total eclipse, the Moon does not disappear entirely but turns a deep, dark red.

Observing and Photographing Lunar Eclipses

When Earth casts its shadow on the Moon it can cause quite a spectacle. Find out how often these events occur, and where you can view them from over the next ten years. You might be familiar with the idea of a solar eclipse: when the Moon passes in front of the Sun from our point of view on Earth, blocking it out and turning day to night for a few minutes on the surface of our planet. But what happens during a lunar eclipse, when will the next one occur and how can you see one?

But the eclipse will not peak until after 7pm GMT, when the lunar orb is closest to the centre of the shadow. Staring directly at a solar eclipse without certified filter glasses can be incredibly damaging to your eyes.

Celestial Objects to Observe. You can unsubscribe anytime. This can only happen when the Moon is full. The dark, central shadow is called the umbra, while the lighter shadow that surrounds it is the penumbra.

This illustration shows the Moon passing through Earth's shadow during a typical lunar eclipse. The Moon is slightly tinted when it passes through the light outer portion of the shadow, the penumbra, but turns dark red as it passes through the central portion of the shadow, called the umbra. Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line.

Four lunar eclipses will appear across Earth's skies in They will all be penumbral eclipses, which means the face of the moon will appear to turn a darker silver color for a few hours. Weather permitting, people across most locations on our planet will catch at least one of the lunar eclipses falling on Jan. There's always a place on Earth where the sun don't shine. In the space above the planet's night side is Earth's cone-shaped shadow. It's impossible to see most of the time, but when the moon passes through part of the shadow, its existence becomes apparent.

Lunar eclipse

Lunar eclipses occur when Earth's shadow blocks the sun's light, which otherwise reflects off the moon. There are three types — total, partial and penumbral — with the most dramatic being a total lunar eclipse, in which Earth's shadow completely covers the moon. The next lunar eclipse will be a penumbral lunar eclipse on June 5, and will be visible from Europe, Africa, Asia and Australia. Throughout history, eclipses have inspired awe and even fear, especially when total lunar eclipses turned the moon blood-red, an effect that terrified people who had no understanding of what causes an eclipse and therefore blamed the events on this god or that. Below, you'll find the science and history of lunar eclipses, learn how they work, and see a list of the next ones on tap. The last lunar eclipse was on July 16, It was a partial lunar eclipse. Here is a schedule of lunar eclipse coming in

Jan 30, - Can you look directly at a lunar eclipse with your eye? The total lunar eclipse is completely safe to look at with the naked eye. There is absolutely.

A partial lunar eclipse could be visible from the UK on Tuesday 16 July. An eclipse of the Moon occurs when the Earth lies directly between the Sun and the Moon and the Moon lies in the shadow of the Earth. For a total lunar eclipse to happen, all three are in a straight line.

The lunar eclipse is this Friday and these are five things you have to know

The third of will happen March As a result, there are two distance extremes of each orbit: closest approach, known as perigee, and the farthest, or apogee. When the Moon is at closest approach and within a day or so of being full, it is called a supermoon because the Moon will be at its brightest and largest. For the supermoon on Feb.

Can You Look at a Lunar Eclipse? How to Safely Watch on January 31

A lunar eclipse occurs when the Moon moves into the Earth's shadow. A lunar eclipse can occur only on the night of a full moon. The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit.

But what exactly is a penumbral lunar eclipse and is it safe to look at? Here's all you need to know.
