What will happen if you look at the lunar eclipse

Site Logo

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.

Lunar and Solar Eclipses

Read our important medical disclaimer. I have a science project and have decided to focus on the eye in relation to solar and lunar eclipses.

Why is it that you can look at a lunar eclipse with the bare eye but not the solar eclipse? In a lunar eclipse, the earth passes between the sun and the moon; making the moon invisible to an observer on earth because there are no light rays reflected off the moon.

Even when looking at the moon immediately before or after the eclipse, the reflected light off the moon does not have the same potential for damage as during a solar eclipse. In a solar eclipse, however, the moon passes between the earth and the sun; making the sun momentarily invisible.

Looking at the sun either before or after the eclipse for any period of time can lead to damage. On a regular day, the brightness of the light makes people unable to stare at the sun and thus avert the damage from the radiation. However during a solar eclipse, a person may get a false sense of security thinking that no damage is occurring because the brightness is much less, but still tremendous radiation emanates from the sun during this period of time.

Unfortunately, if you do not protect your eyes during an eclipse using special solar eclipse glasses search online for these , you can suffer a burn of the retina manifesting in a blind spot.

Watching Lunar Eclipses

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.

A solar eclipse will occur across most of the United States on April 8, , including a small band of total solar eclipse stretching from east to west across much of the continent. Before you do, please take the time to learn about the dangers to your vision and how to protect your eyes from injury during the eclipse.

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. A full lunar eclipse is often called a blood moon because the Moon becomes a bright reddish colour.

What is a partial lunar eclipse and is it safe to look at directly?

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. A supermoon also occurred in January with a slightly more distant perigee, a mere miles kilometers farther away, but 14 hours after the full Moon. The third and last supermoon of the year will happen March 19, when the perigee distance will be reached a day and five hours before the full Moon see the table below for details. The Moon will look extremely large when it rises and sets. Because these relatively close objects are in front of the Moon, our brain is tricked into thinking the Moon is much closer to the objects that are in our line of sight. At Moon rise or set, it only appears larger than when it is directly overhead because there are no nearby objects with which to compare it.

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

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. In this case the Earth's shadow hides the Moon from view.

A partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the they don't form a straight line in space. A small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra.

No part of this eclipse will be visible from North America. Visibility will be confined to central and east Africa, Eastern Europe, western and central Asia, most of Indonesia and Australia. Because at this moment in time the Moon is situated at a distance of , miles from Earth, its disk will appear slightly smaller than the Sun; four-tenths of one percent smaller to be exact. As such, when the Moon passes squarely in front of the Sun, it will not totally cover it, but instead, a narrow ring of sunlight will remain visible.

Lunar eclipse guide: What they are, when to see them and where

In the US, the eclipse will peak at 9. When this happens, sunlight directly blotted out by the Earth will cast a red-tinged shadow into space and onto the face of the Moon. Astronomers strongly advise against looking at solar eclipses without protection due to the harmful UV rays radiating from the star.

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. Failure to use appropriate filtration may result in permanent eye damage or blindness. Looking at the Sun through any kind of optical aid binoculars, a telescope, or even a camera's viewfinder is extremely dangerous, and can cause permanent blindness.

During a lunar eclipse, the Earth comes between the path of the Moon and the Sun and casts a shadow on its Jul 16, - Uploaded by IndianExpressOnline.

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.

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?

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.

Update for 6 p. EST: The first lunar eclipse of has ended.

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.
