By Anne Buckle and Aparna Kher. One of the easiest ways to safely watch a solar eclipse is to use 2 sheets of cardboard and make your own simple pinhole projector. Never look directly at the Sun without proper eye protection. You can seriously hurt your eyes and even go blind.

The simplest and quickest way to safely project the Sun is with a projector made from only 2 pieces of card or paper. A box projector works on the same principles, it requires a little more time and a few extra items to construct, but it is more sturdy. Topics: Astronomy , Eclipses , Sun.

DIY: Simple Card Projector The simplest and quickest way to safely project the Sun is with a projector made from only 2 pieces of card or paper.

You Need: 2 pieces of stiff white cardboard, e. Make sure that the hole is round and smooth. With your back towards the Sun, hold 1 piece of paper above your shoulder allowing the Sun to shine on the paper. The 2nd sheet of paper will act as a screen. Hold it at a distance, and you will see an inverted image of the Sun projected on the paper screen through the pinhole.

To make the image of the Sun larger, hold the screen paper further away from the paper with the pinhole. Keep Safe! Never look at the Sun directly without protective eye gear. Even sunglasses cannot protect your eyes from the damage the Sun's rays can do to them.

Always keep your back towards the Sun while looking at a pinhole projection. Do not look at the Sun through the pinhole, binoculars or telescope.

What Are Total Solar Eclipses?

There are close to confirmed moons orbiting six major planets in our solar system Mercury and Venus lack moons. But any given spot on our planet's surface gets darkened by the Moon's shadow on average only once about every years, so in that sense totality is indeed rare. The Sun is also on average about times farther away. This truly remarkable coincidence is what gives us total solar eclipses. If the Moon were slightly smaller or orbited a little farther away from Earth, it would never completely cover the solar disk.

A solar eclipse occurs when a portion of the Earth is engulfed in a shadow cast by the Moon which fully or partially blocks sunlight. This occurs when the Sun , Moon and Earth are aligned.

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. Never look directly at the sun during a solar eclipse except during the very brief time the sun is in total eclipse; and even then, with caution. Looking directly at the sun can cause permanent damage to your eyes. A solar eclipse occurs when the moon moves between the sun and the earth.

Lunar Eclipses and Solar Eclipses

F or the first time in U. ET on Monday. But those who watch this rare celestial event in person need to take precautions, because staring right at the sun can quickly harm your eyes. The path of totality, which is about 70 miles wide, is viewable from parts of 14 states, as shown on this solar eclipse map , and only lasts a maximum of two minutes and 40 seconds, according to NASA. Before and after the total solar eclipse, those in its path will see a partial eclipse, in which the moon only partly blocks the sun. The rest of the country will also see a partial eclipse — so essentially, everyone needs to prepare themselves to view the eclipse safely. According to experts, viewing the sun with your naked eye during the eclipse can burn your retina, damaging the images your brain can view. It is not possible to go completely blind from looking at the eclipse, Chou said, because the injury is limited to the central part of your visual field.

Why is it dangerous to look at the solar eclipse directly specially at that moment?

Remember to use safe solar eclipse glasses and other equipment during the partial phases, and soak up the darkness during totality! In fact, you've probably been told that by lots of reputable sources including our own Space. A total solar eclipse happens when the central disk of the sun is completely covered by the moon. But total solar eclipses are a much rarer sight. A joint statement from NASA and the four other organizations says that with the right information, skywatchers can safely view the total solar eclipse in its full glory with the naked eye.

The What: Eye Safety

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.

By Vigdis Hocken and Aparna Kher. Total solar eclipses occur when the New Moon comes between the Sun and Earth and casts the darkest part of its shadow, the umbra, on Earth. A full solar eclipse, known as totality, is almost as dark as night. During a total eclipse of the Sun, the Moon covers the entire disk of the Sun. In partial and annular solar eclipses, the Moon blocks only part of the Sun. Eclipses are normally named after their darkest phase.

Solar eclipse

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.

A total solar eclipse is one of the most awe-inspiring events in nature, but astronomers and ophthalmologists warn that looking at the sun without solar eclipse glasses or other protection can damage your eyes and cause permanent blindness. Totality, the brief period when the moon completely covers the sun, is the only safe time to watch with the naked eye. Lasting from seconds to a maximum of 7. The sun is basically a huge, continuous thermonuclear explosion, which produces intense radiation across the spectrum from infrared to ultraviolet light and beyond. Infrared light is absorbed by many materials and is readily converted to heat, while ultraviolet light is the source of sunburn.
