Lunar eclipse can you see the moon
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.

How to see tonight’s ‘Wolf moon’ 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 The first of four penumbral lunar eclipses of arrives on Jan. This will be the first of four penumbral lunar eclipses in The moon will take on a tea-stained appearance during this eclipse, which begins at p.
The moon will again take on a slight saturation during the penumbral lunar eclipse of June, 5 The coloring will occur across half of the lunar face.
Central and western Africa, southeast Asia and most of Australia will view the entire penumbral lunar eclipse, which begins at p. The third penumbral lunar eclipse of will be visible from all of South America and most of North America. The slight shading will appear over less than half of the lunar face, peaking at a. This eclipse will begin at p. The moon will have a tea-stained appearance across most of its face during the final penumbral lunar eclipse of It will be visible from most places on the Earth except the African continent, the majority of Europe and central Eurasia.
It will begin at a. The next total lunar eclipse, or "blood moon," won't occur until May 26, , and it will be visible from eastern Asia, Australia, the Pacific Ocean and much of the Americas.
A partial lunar eclipse will follow on Nov. Those will be the only two lunar eclipses in NASA keeps a list predicting lunar eclipses until They also keep data about past lunar eclipses. During the 21st century, Earth will experience a total of lunar eclipses, according to the space agency. A lunar eclipse can occur only at full moon. A total lunar eclipse can happen only when the sun, Earth and moon are perfectly lined up — anything less than perfection creates a partial lunar eclipse or no eclipse at all.
Some understanding of simple celestial mechanics explains how lunar eclipses work. Because the moon's orbit around Earth lies in a slightly different plane than Earth's orbit around the sun, perfect alignment for an eclipse doesn't occur at every full moon. A total lunar eclipse develops over time, typically a couple hours for the whole event. Here's how it works: Earth casts two shadows that fall on the moon during a lunar eclipse: The umbra is a full, dark shadow.
The penumbra is a partial outer shadow. The moon passes through these shadows in stages. The initial and final stages — when the moon is in the penumbral shadow — are not so noticeable, so the best part of an eclipse is during the middle of the event, when the moon is in the umbral shadow.
Total eclipses are a freak of cosmic happenstance. Ever since the moon formed, about 4. The setup right now is perfect: the moon is at the perfect distance for Earth's shadow to cover the moon totally, but just barely. Billions of years from now, that won't be the case. According to NASA, two to four solar eclipses occur each year, while lunar eclipses are less frequent.
However, while solar eclipses can only be seen along a roughly mile wide path, each lunar eclipse is visible from over half the Earth. Total lunar eclipse : Earth's full umbral shadow falls on the moon. The moon won't completely disappear, but it will be cast in an eerie darkness that makes it easy to miss if you were not looking for the eclipse.
Some sunlight passing through Earth's atmosphere is scattered and refracted, or bent, and refocused on the moon, giving it a dim glow even during totality. If you were standing on the moon, looking back at the sun, you'd see the black disk of Earth blocking the entire sun, but you'd also see a ring of reflected light glowing around the edges of Earth — that's the light that falls on the moon during a total lunar eclipse.
Partial lunar eclipse : Some eclipses are only partial. But even a total lunar eclipse goes through a partial phase on either side of totality. During the partial phase, the sun, Earth and moon are not quite perfectly aligned, and Earth's shadow appears to take a bite out of the moon. Penumbral lunar eclipse : This is the least interesting type of eclipse, because the moon is in Earth's faint outer penumbral shadow. Unless you're a seasoned skywatcher, you likely won't notice the effect, in which the moon is subtly shaded by Earth's shadow.
The moon may turn red or coppery colored during the total portion of an eclipse. The red moon is possible because while the moon is in total shadow, some light from the sun passes through Earth's atmosphere and is bent toward the moon. While other colors in the spectrum are blocked and scattered by Earth's atmosphere, red light tends to make it through easier.
The effect is to cast all the planet's sunrises and sunsets on the moon. Christopher Columbus leveraged a blood-red eclipse in to frighten natives on Jamaica into feeding him and his crew.
It was on Columbus' fourth and final voyage to the New World. An epidemic of shipworms ate holes in the ships of his fleet; Columbus' was forced to abandon two ships. He then beached his last two on Jamaica on June 25, The natives welcomed the castaways and fed them. But after six months, Columbus' crew mutinied, and robbed and murdered some of the Jamaicans, who had grown weary of feeding the crew.
Columbus had an almanac that foretold a lunar eclipse on Feb. He met the local chief, and told him the Christian god was angry with his people for no longer supplying food. Columbus said to expect a sign of God's displeasure three nights later, when he would make the full moon appear "inflamed with wrath. Just before the total phase of the eclipse was about to end, Columbus said God had pardoned the natives and would bring the moon back.
The crew was well fed until help arrived in November and Columbus and his men sailed back to Spain. Lunar eclipses are among the easiest skywatching events to observe. Simply go out, look up and enjoy. You don't need a telescope or any other special equipment. However, binoculars or a small telescope will bring out details in the lunar surface — moonwatching is as interesting during an eclipse as anytime. If the eclipse occurs during winter, bundle up if you plan to be out for the duration — an eclipse can take a couple hours to unfold.
Bring warm drinks and blankets or chairs for comfort. If you want to photograph the next lunar eclipse, be sure to check out our guide by veteran astrophotographers Imelda Joson and Edwin Aguirre.

What Is a Total Lunar Eclipse?
There are lots of exciting lunar events to look forward to this year, including four lunar eclipses. First, a brief explanation of what we mean when we say "lunar eclipse. A penumbral lunar eclipse occurs when the moon passes through the penumbra, or the outermost section of Earth's shadow. All four eclipses in are penumbral eclipses, and the moon will be cloaked in a darker-than-usual, silvery hue. There are four lunar eclipses scheduled for
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.
While not as spectacular as a solar eclipse , a lunar eclipse can still be a beautiful and amazing spectacle. It's also a lot easier to see a total lunar eclipse than its solar equivalent! A lunar eclipse always occurs at night, during a Full Moon ; you should be able to see the eclipse if it occurs during your nighttime, and you have a view of the Moon. But what you will see depends on the specific type of the eclipse. By the way, since a lunar eclipse occurs at night, when the Sun isn't around, it's always safe to look at a lunar eclipse. As described in Mechanics of Lunar Eclipses , the Earth's shadow during a lunar eclipse has two parts: the penumbra , where the Sun's light is only partly blocked from the Moon; and the umbra , where the Earth totally blocks the Sun's light. If the Moon touches the penumbra, a penumbral eclipse will be seen although, in practice, this type of eclipse is subtle; most penumbral eclipses can't bee seen with the naked eye ; if the Moon touches the umbra, a partial umbral eclipse will be seen; and if the Moon completely enters the umbra, the result is a total umbral eclipse , or total lunar eclipse. A total eclipse is always preceded and followed by a partial eclipse; which is in turn preceded and followed by a penumbral eclipse. Hence, we say that a total eclipse goes through a penumbral stage, then a partial stage, then the total stage, then partial, then penumbral, before finishing.
Lunar Eclipses: What Are They & When Is the Next One?
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.
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. This means that the Moon passes through the darkest part of the Earth's shadow.

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.SEE VIDEO BY TOPIC: First impact flash ever spotted on the Moon during a lunar eclipse
By Vigdis Hocken and Aparna Kher. A total lunar eclipse takes place when the Earth comes between the Sun and the Moon and covers the Moon with its shadow. When this happens, the Moon can turn red, earning it the nickname of Blood Moon. The astronomical term for this type of alignment is syzygy , which comes from the Greek word for being paired together. The Moon does not have its own light but shines because its surface reflects the Sun's rays.

The moonlight we see on Earth is sunlight reflected off the Moon's grayish-white surface. The amount of Moon we see changes over the month — lunar phases — because the Moon orbits Earth and Earth orbits the Sun. Everything is moving. During a lunar eclipse , Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. Earth's shadow covers all or part of the lunar surface.

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.
When Is the Next Lunar Eclipse?
Lunar eclipses are common. On average they happen twice a year. But only half the world gets to view any Lunar eclipse, and some eclipses--penumbral eclipses--are hardly noticeable.
