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.

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.

During a total lunar eclipse, the Earth comes between the Sun and the Moon and blocks any direct sunlight from reaching the Moon. The Sun casts the Earth's shadow on the Moon's surface. Types of Eclipses. For a lunar eclipse to occur, the Sun, Earth, and Moon must be roughly aligned in a line.

Otherwise, the Earth cannot cast a shadow on the Moon's surface and an eclipse cannot take place. When the Sun, Earth, and Moon come together in a straight line, a total lunar eclipse takes place. When the three bodies are aligned in a way that the Moon is partly covered by the Earth's umbra, a partial lunar eclipse is the result. On the other hand, if only the outer part of Earth's shadow covers the Moon, a penumbral lunar eclipse takes place.

Earth's umbra extends into space far beyond the orbit of the moon. This means that Earth's antumbra plays no role in lunar eclipses. Lunar nodes are the locations where the Moon crosses the Earth's orbital plane.

Why don't we see a lunar eclipse every month if a Full Moon is needed for a total lunar eclipse? The points where the two orbital planes meet are called lunar nodes. Lunar eclipses occur when a Full Moon happens near a lunar node. Even though Earth blocks sunlight from directly reaching the surface of the Moon during a total lunar eclipse, the Moon is still visible to the naked eye.

This is because Earth's atmosphere bends sunlight and indirectly lights up the Moon's surface. When sunlight passes through the Earth's atmosphere, it gets refracted towards the Earth's surface , and part of it—the colors with shorter wavelengths—gets scattered and filtered out , while the rest, colors with longer wavelengths like orange and red, passes through the atmosphere.

This light is once again refracted towards the surface of the fully eclipsed Moon, thus illuminating it in a reddish-orange glow. Because of this, a total lunar eclipse is sometimes colloquially called a Blood Moon. Why does the Moon look red? A lunar eclipse can also be yellow, orange, or brown in color. This is because different types of dust particles and clouds in Earth's atmosphere allow different wavelengths to reach the surface of the Moon.

A series of four consecutive total lunar eclipses with no partial or penumbral lunar eclipses in between is called a lunar tetrad.

In recent years, eclipses in a lunar tetrad have also been popularly called Blood Moons. This usage of the term has no technical or astronomical basis and it is thought that it has Biblical origins. A total lunar eclipse usually happens within a few hours. Totality can range anywhere from a few seconds to about minutes.

The July 26, total lunar eclipse had one of the longest periods of totality in the 20th century— minutes and 43 seconds. Almost everyone on the night side of Earth can see a total eclipse of the Moon. Because of this, most people have higher chances of seeing a total lunar eclipse than a total solar eclipse , even though both occur at similar intervals.

Unlike solar eclipses , observing a total lunar eclipse does not require any special equipment. Lunar eclipses are safe to see with the naked and unaided eye. On average, a total lunar eclipse can be seen from any given location every 2. More details about upcoming Eclipses. Topics: Astronomy , Eclipses , Moon , Sun.

Earth Blocks the Sunlight The Moon does not have its own light but shines because its surface reflects the Sun's rays. Types of Eclipses Earth's Three Shadows Earth's shadow can be divided into three parts: Umbra - the darker, central part. Penumbra - the outer part. Antumbra - the partly shaded area beyond the umbra. Why are there three shadows? During a total lunar eclipse, Earth's umbra completely covers the Moon.

Total lunar eclipses happen only when: It is Full Moon. At the same time, the Moon is at or very near a lunar node, so the Sun, the Moon, and the Earth are aligned in a straight or nearly straight line.

Phases of the Moon Why don't we see a lunar eclipse every month if a Full Moon is needed for a total lunar eclipse? How to see a Lunar Eclipse? The Moon Looks Red Even though Earth blocks sunlight from directly reaching the surface of the Moon during a total lunar eclipse, the Moon is still visible to the naked eye.

Different Colored Eclipses A lunar eclipse can also be yellow, orange, or brown in color. Tetrads and Blood Moons A series of four consecutive total lunar eclipses with no partial or penumbral lunar eclipses in between is called a lunar tetrad.

There are 7 stages of a total lunar eclipse: Penumbral eclipse begins : This begins when the penumbral part of Earth's shadow starts moving over the Moon. This phase is not easily seen by the naked eye. Partial eclipse begins : Earth's umbra starts covering the Moon, making the eclipse more visible. Total eclipse begins : Earth's umbra completely covers the Moon and the Moon is red, brown, or yellow in color.

Maximum eclipse : This is the middle of the total eclipse. Total eclipse ends : At this stage, Earth's umbra starts moving away from the Moon's surface. Partial eclipse ends : Earth's umbra completely leaves the Moon's surface. Penumbral eclipse ends : At this point, the eclipse ends and Earth's shadow completely moves away from the Moon. What is earthshine? No Special Equipment Needed Unlike solar eclipses , observing a total lunar eclipse does not require any special equipment.

Lunar eclipse

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.

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.

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.

Lunar Eclipses: What Are They & When Is the Next One?

Find out what a lunar eclipse is and when the next total lunar eclipse in the UK will occur, as well as expert tips on how to see it from astronomers at the Royal Observatory Greenwich. 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 bodies lie in a straight line. During a total lunar eclipse, the Moon usually turns a deep, dark red because it is illuminated by light that has passed through the Earth's atmosphere and has been bent back towards the Moon by refraction. During the partial phase of the eclipse, part of the Moon travels through the Earth's full 'umbral' shadow. However, on this occasion only a very small section of the Moon will be covered by the umbra at maximum eclipse, though the whole northern half of the Moon will be darkened by the penumbral shadow. Find out more. A penumbral lunar eclipse occurs when the Moon travels only through the outer, fainter part of the Earth's shadow, or 'penumbra'. This happens when the Earth moves between the Sun and Moon but the three do not form a perfectly straight line.

A Space Place Trivia Alert! While we call it a solar eclipse , astronomers call it an occultation. An occultation happens when an object blocks your view of another object. In this case, the moon blocks your view of the sun.

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.

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.

Watching Lunar Eclipses

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.
