A total solar eclipse is probably the most spectacular astronomical event that most people will experience in their lives. There is a great deal of interest in watching eclipses, and thousands of astronomers both amateur and professional travel around the world to observe and photograph them. A solar eclipse offers students a unique opportunity to see a natural phenomenon that illustrates the basic principles of mathematics and science that are taught through elementary and secondary school. Indeed, many scientists including astronomers! Teachers can use eclipses to show how the laws of motion and the mathematics of orbital motion can predict the occurrence of eclipses.

Please refresh the page and retry. Solar eclipses have captivated and mystified mankind for centuries. But what's the safest way to view one? The most important message is never to look directly at the Sun, even through sunglasses or dark material such as a bin liner or photographic negative.

Makeshift filters may not screen out the harmful infrared radiation that can burn the retina of the eye. Here are some of the best safe methods of observing the magical moment when the Moon moves in front of the Sun. Cover a small flat mirror with paper that has a small hole cut in it. The hole does not have to be circular but should be no wider than 5mm. A larger hole will produce a brighter but fuzzier image.

Prop up or clamp the mirror so that it reflects the sunlight onto a pale screen or wall, ideally through a window. A projection distance of five metres The eclipse can be seen in the image as the Moon starts to take a "bite" out of the Sun, appearing upside down compared with its position in the sky. The smaller the mirror and further away the wall, the sharper the image will be. Experiment with the distances and mirror size. Do not look into the mirror during the eclipse as this is just as dangerous as looking directly at the Sun.

A big advantage of this method is that it allows a number of people to watch the eclipse at the same time - ideal for schools. Pinholes allow light through them and can create an image like a lens. Make a small hole in a piece of card using a compass or other sharp-pointed implement.

Standing with your back to the Sun, position another white card behind the one with the pinhole so that the Sun projects an image onto it. An alternative method uses a cereal box or something similar. Make a pinhole in one edge, point it towards the Sun, and a tiny image will be seen projected onto the inside of the box.

A piece of white paper or card placed inside will make it easier to see. Cover one eyepiece of a pair of binoculars with a lens cap and face the "big" end of the binoculars towards the Sun. The uncovered lens will project an image of the Sun that can be cast onto a plain card held about a foot away.

Use the focus wheel to sharpen the image. Ideally, the binoculars should be fastened to a tripod or stand. A cardboard "collar" with holes cut to fit the large lenses will shade the card on which the image is projected. Take an ordinary kitchen colander and stand with your back to the Sun holding it in one hand and a piece of paper in the other. These are the only way of viewing the eclipse directly, other than through a telescope fitted with a professional filter.

Similar to 3D glasses, eclipse viewers are made from card and inlaid with a special material that cuts the Sun's light down , times. If using a viewer, check for holes or scratches as it is only safe if undamaged. It might sound boring but the safest way to see an eclipse is to view it indirectly from the comfort of your home.

The holes in the colander can be used to project multiple eclipse images onto the paper.

Eye Safety During Solar Eclipses

Whereas lunar eclipses are safe to view with the naked eye, solar eclipses are not. You must take the necessary precautions to keep from harming your eyesight. This can only occur during a new moon, when the moon passes between the sun and Earth. A solar eclipse begins as a small notch slowly appears along one edge of the sun.

A solar eclipse is when the moon blocks any part of the sun. Can a solar eclipse damage your eyes? A solar eclipse can damage your eyes if safety measures are not employed.

Martin Mobberley. To children the world is full of magical events, and the line between make-believe and reality is happily distinctly blurred. However, as we all age and have to be realistic, earn money, become serious and responsible adults yawn! We accept that the worlds of make-believe are simply a product of the vivid imagi- tions of great story tellers, and that we are all very similar human beings; just sl- ging away at the tedious day job, and hoping for a win on the lottery.

Solar eclipse and the eyes

Both total solar eclipses AND partial solar eclipses require specialized eye protection. Failure to use proper observing methods may result in permanent eye damage or severe visual loss. Never risk your eyesight. As my new book Zapped makes clear, solar radiation includes fascinating components like ultraviolet waves. But right now we are concerned about the immediate damage produced by looking directly at the sun without adequate eye protection. The sun sets during a the partial solar eclipse of May Even high-intensity visible light can produce retinal burns resulting in temporary or even a permanent loss of visual function. This photochemical injury occurs mainly when the retina is exposed to the blue and green components of sunlight.

How to Photograph a Solar Eclipse

Originally published in and first revised in , The Art of Photography has sold well over , copies and has firmly established itself as the most readable, understandable, and complete textbook on photography. Featuring nearly beautiful photographs in both black-and-white and color, as well as numerous charts, graphs, and tables, this book presents the world of photography to beginner, intermediate, and advanced photographers who seek to make a personal statement through the medium of photography. Without talking down to anyone or talking over anyone's head, renowned photographer, teacher, and author Bruce Barnbaum presents how-to techniques for both traditional and digital approaches. In this newest edition of the book, Barnbaum has included many new images and has completely revised the text, with particular focus on two crucial chapters covering digital photography: he revised a chapter covering the digital zone system, and includes a brand-new chapter on image adjustments using digital tools. Throughout the book, Barnbaum goes well beyond the technical, as he delves deeply into the philosophical, expressive, and creative aspects of photography so often avoided in other books.

All rights reserved. We've all heard the warnings before: Looking directly at the sun, whether it's with your naked eyes or through an optical aid, can be extremely dangerous. This holds true on any regular sunny day—and when there is a partial solar eclipse.

How to view the solar eclipse safely - and without glasses

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.

Practical Astrophotography. Jeffrey R. Almost all amateur astronomers want to take photographs of the night sky. For all but the simplest star-trail pictures, this involves machinery - a telescope drive - to track the stars, essential to compensate for the rotation of the earth. The task becomes even more complicated when photographing very small or very faint objects that require high magnification or very long exposure times. Amateurs have many options according to their requirements, technical ability, and budget.

Solar Eclipse and Your Eyes

For those of us who waited too long to snag a pair of safe, legit solar-viewing glasses , using a phone as an intermediary to view the eclipse sounds like a clever, accessible hack. If you point your phone at the full, bright sun, it will immediately respond by darkening the entire view, just as your eyes are averse to staring directly at the sun. But the dimming of the sun during a partial eclipse can confuse your phone, too, and cause your phone screen to burn too brightly where there is a sliver of sun. This can cause damage to your phone, including the burning out of pixels on your screen. How risky this is really depends on what phone you own Androids seems to be more prone to damage, iPhones less so and how long you expose said phone to the eclipse. You can keep your phone safe the same way you keep your eyes safe — by placing an appropriate solar filter over the lens.

The metallic silver contained in the film emulsion is the protective filter; that are not safe - if you can see through the CD in normal room lighting, don't use it!! The fact that the Sun appears dim, or that you feel no discomfort when looking at.

Вскоре путь ей преградила кабина голосового сканирования, табличка на которой гласила: АГЕНТСТВО НАЦИОНАЛЬНОЙ БЕЗОПАСНОСТИ (АНБ) ОТДЕЛЕНИЕ КРИПТОГРАФИИ ТОЛЬКО ДЛЯ СОТРУДНИКОВ С ДОПУСКОМ Вооруженный охранник поднял голову: - Добрый день, мисс Флетчер. - Привет, Джон. - Не ожидал, что вы придете. - Да, я.  - Она наклонилась к микрофону и четко произнесла: - Сьюзан Флетчер.

Неужели высвободился. Однако тот не подавал никаких признаков жизни. Сьюзан перевела взгляд на помост перед кабинетом Стратмора и ведущую к нему лестницу. - Коммандер.

Директор. Директор! - кричал. ГЛАВА 95 Кровь Христа… чаша спасения… Люди сгрудились вокруг бездыханного тела на скамье. Вверху мирно раскачивалась курильница.

Сквозь строй - лучший антивирусный фильтр из всех, что я придумал. Через эту сеть ни один комар не пролетит.

Садись, Сьюзан. Я должен тебе кое-что сказать.  - Она не пошевелилась.  - Когда я все закончу, я сообщу тебе код вызова лифта.

Все десять присутствовавших при этом человек в напряженном ожидании молчали, когда вдруг заработавший принтер выдал им открытый текст: шифр был взломан. ТРАНСТЕКСТ вскрыл ключ, состоявший из шестидесяти четырех знаков, за десять с небольшим минут, в два миллиона раз быстрее, чем если бы для этого использовался второй по мощности компьютер АНБ. Тогда бы время, необходимое для дешифровки, составило двадцать лет.

Производственное управление АНБ под руководством заместителя оперативного директора коммандера Тревора Дж. Стратмора торжествовало победу. ТРАНСТЕКСТ себя оправдал.

Это невозможно! - воскликнула она.  - Вы проверили сигналы ошибки. Быть может, в ТРАНСТЕКСТЕ какой-нибудь сбой и… - Все в полном порядке.
