Can we see solar eclipse with x ray
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.

Ask An Astronomer: Your Questions about the Annular Solar Eclipse, Answered
Updated: May 11, Reader-Approved References. Catching sight of an eclipse is a wonderful event, and there are people who invest much time and love into chasing eclipses around the world.
At its most basic, an eclipse occurs when one object passes through the shadow of another. While most people are familiar with solar eclipses, there are actually both solar and lunar eclipses and both are worth the effort if you're a serious stargazer; no words or photos can ever replace the experience of seeing an eclipse for yourself. While using things like sunglasses, binoculars, or telescopes may seem like a good idea, none of these methods will be strong enough to protect your eyes. Instead, try making an eclipse viewer by poking a small hole through a piece of cardstock.
Then, place another piece of cardstock on the ground to serve as a projection screen. Standing with your back to the sun, hold the card with the hole a few feet off the ground, in the direction of the sun. At the same time, face the screen you placed on the ground and align it with the cardstock in your hand until you can see a perfect circle on the screen. When the eclipse takes place, the circle will turn into a crescent or a thin-lined O, depending on the type of eclipse.
Viewing a Lunar Eclipse. Preparing to View an Eclipse. Tips and Warnings. Things You'll Need. Related Articles. Article Summary. Part 1 of Read about a solar eclipse. Solar eclipses occur when the sun, the moon, and the Earth are all in alignment allowing the moon to block the sunlight from reaching the Earth.
The amount of time a total eclipse lasts can be from a few seconds to a maximum of seven and half minutes, as the umbra moves along the "path of totality". There is also an "annular eclipse" when the moon slides across the sun, but doesn't completely cover it. Be aware of the methods that shouldn't be used for viewing a solar eclipse. You shouldn't look at eclipses through binoculars , telescopes , any type of glasses, sunglasses, smoked glass, polarizing filters, or exposed color film — none of these methods are strong enough to protect your eyes.
Make an eclipse viewer or a pinhole projector. A homemade eclipse viewer or pinhole viewer is very simply done and, generally speaking, it is the easiest and safest way to view an eclipse for just the price of some thick poster paper or cardstock. Its drawback is the very small image it produces, but this one is ideal for children and young teens who will enjoy the process of preparing the pinhole projector and then using it.
Place a second piece of paper on the ground to serve as the screen you will be projecting the eclipse onto. Standing with your back to the sun, hold the card a few feet off the ground above your shoulder or to your side. Make sure your head is not covering up the hole. It should be held in the direction of the sun and you should be facing the screen you placed on the ground.
When the projector is properly aligned, you should see a perfect circle on the other piece of card you placed on the ground.
The circle may appear fuzzy at the edges. You can bring it into sharper focus by moving the pinhole projector closer or further away from the ground.
When the eclipse takes place, that circle will shrink and turn into a crescent, if it is a partial eclipse. If it is a total eclipse, then it will turn into a thin-lined O. You can also use a pinhole camera for eclipse viewing. Use a solar filter on your viewing equipment. If you choose to look at the sun with your eyes rather than by projecting the sun onto something else , then you must always have a solar filter between you and the eclipse.
While it is possible to view a total solar eclipse without protection during totality , only an experienced observer will know when to judge this moment accurately and when it is essential to immediately place the filter between your eyes and the eclipse again: before the sun reappears.
Solar filters are available for all viewing equipment camera, binoculars, and telescope. When selecting a solar filter for a telescope or binoculars , it is absolutely vital that you choose a filter made for your exact model and brand. If the filter does not fit properly, or is used incorrectly, permanent eye damage can occur. View an eclipse indirectly by making a projection. Projection of the eclipse image through binoculars or a telescope is another safe method to view the eclipse indirectly.
However, it is only safe if you use it for projection, not for looking through — do NOT look through the binoculars or telescope doing the projecting! With your back to the sun, hold the binoculars with one hand and aim them towards the eclipse so that the uncovered lens picks up the eclipse. Use the shadow of the binoculars to help you align the binoculars. Watch the image projected back onto a screen, wall, or large piece of white paper that you're holding in your free hand.
Just move the binoculars around until the eclipse image appears on the card, screen, or wall. The further you hold the card away from the eyepiece, the larger the image will be. When you get used to using this method, try fixing the binoculars to something like a tripod or propping them up against a chair or table. The image will benefit from the increased steadiness. If you're using this method to observe the sun during a non-eclipse time, shift the binoculars away from the sun every minute to prevent overheating of the equipment.
Let the optical equipment cool down for a few minutes before trying again. Use welder's glass. Shade number 14 or higher welder's glass is one of the most affordable and widely available filters you can use to observe the sun with unaided eyes. The glass must completely cover your eyes at all times of observation. Again, all of the lens must be covered and if it can only cover one lens, cap the other one. Use mounted filters. There are special types of filters that can be purchased that mount directly onto a telescope or pair of binoculars.
While some of these can get quite expensive, there are cheaper versions that will still protect your eyes and allow you to view the sun. There are several important warnings you must take heed of when purchasing and mounting a solar filter:  X Research source You must be absolutely sure that the filter is a proper solar filter, as ordinary photographic filters will not filter the dangerous rays.
The filter must fit your brand and type of equipment perfectly. Always buy the filter from a reputable dealer; if you have any concerns about the safety of the filter, do not use it and if you need advice, take it to your local planetarium or astronomy club for expert advice.
Check for surface damage prior to mounting. Mylar is easy to puncture or rip and if that has happened, the filter cannot be used. Be sure that the filter is secure once on; if you need to tape it as well as mount it to ensure that it won't come off or loosen, then do so. Do not use filters that screw into the eyepiece end of binoculars or telescopes. The focused light can burn through or crack the filter at this end owing to the intense heat of the sun being concentrated; just the tiniest crack or separation in the filter can permanently damage your eyes.
Only use filters that mount onto the front end of the telescope. Part 2 of Read about lunar eclipses. Lunar eclipses occur less frequently than total eclipses of the sun, with a lunar eclipse taking place about twice a year, and a total lunar eclipse happening on average every two to three years. A lunar eclipse occurs when the full moon travels into the Earth's shadow and becomes a coppery or dull-red color a "Blood Moon".
Like solar eclipses, there are total and partial lunar eclipses that depend on the alignment of the Earth, the sun, and the moon. Be prepared to stay up late. A lunar eclipse occurs only during a full moon when it is perfectly aligned with the Earth and the sun.
The eclipse happens because the Earth casts a shadow on the moon. Lunar eclipses usually occur late at night over a period of hours as the moon passes in and out of the shadow cast by the Earth. If you want to see the whole thing, you will have to stay up late. View with your naked eye or through magnifying objects as desired. Lunar eclipses are perfectly safe to observe with your eyes and without a filter. If you'd like to photograph the lunar eclipse, read How to Photograph the Moon for more details on moon photography or How to Photograph an Eclipse for advice on photographing both solar and lunar eclipses.
What are the best ways to view a solar eclipse?
On December 26, , the third and final solar eclipse of the year will provide a visual treat to several parts of India between 8 am and am IST. This eclipse will be an annular solar eclipse — a type of eclipse that occurs when the apparent diameter of the Moon is smaller than that of the Sun. Abhay Deshpande, a Senior Scientist Physicist working for the Government of India as well as the Honorary Secretary of Khagol Mandal, an non-profit collective of astronomy enthusiasts who organise various sky observation programmes, lectures and study tours. An eclipse is a rare phenomenon seen from Earth. In a solar eclipse, the Moon comes between the Sun and the Earth and covers the Sun.
Bengaluru : A day after Christmas, on 26 December, the moon will gently glide in between the Earth and Sun, blocking the view of Sun completely and leaving only its outer edges to form a bright ring around the moon. This is called an annular solar eclipse and will be visible in several countries in Asia, including India. The annular ring will, however, be seen only in parts of Karnataka, Kerala and Tamil Nadu. Kannur in Kerala will be the first city in India where the ring will be visible.

How to see 2019’s last celestial treat — a solar eclipse with a ring of fire
T he solar eclipse occurring on December 26 is not only the last one this year, but is also going to very special. The spectacle will be visible in parts of South India. People in the rest of India need not despair, a partial eclipse will be visible everywhere in India. The eclipse will commence at am.
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.
How to View a Solar Eclipse
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.
A solar eclipse occurs when the moon passes between the sun and the earth, and the moon fully or partially obscures the sun. It is extremely dangerous to look directly at the sun even during a solar eclipse. You should never attempt to observe a total, partial or annular eclipse with the naked eye. The safest technique for viewing a solar eclipse is indirect viewing. For example you can easily project an image of the sun onto a screen or you can view live streams on TV or online. Children's eyes in particular are extremely delicate and transmit more light through to the retina.
