During the total solar eclipse in 1919 , scientists verified that light from remote stars could be bent by the gravity of the sun - just as einstein predicted . einstein became world famous overnight 1919年,當日食觀測隊藉日全食時證實來自遙遠恒星的光線被太陽的重力所偏折恰如愛因斯坦的預測一樣,一夜之間,愛因斯坦成為全世界的知名人物。

However , because the path of the total eclipse is very narrow , if you stay in one place and wait , probably you will not see even one total solar eclipse in your life time 可惜的是,由于全食帶非常狹窄,每次發生日全食,世界上只有很少地方可以看到。假若你妄圖以靜制動,留在一地守株待免,恐怕終其一生也不會看到一次日全食。

Solar eclipses occur when the sun is obscured by the moon , an occasion when the sun , the moon and the earth are in near alignment , and the earth moves into the moon s umbra or penumbra 日食是太陽被月球所掩蓋的自然現象。當太陽月球及地球接近排成一條直線時,地球便會進入月球的本影或半影,日食便會發生。

Due to the tidal friction , the moon is receding from us . tens of thousand of years later , the angular size of the moon will be so small that there will be no total solar eclipse anymore 由于潮汐摩擦作用,月球正逐漸遠離地球,數萬年后,月球的視直徑會變得很小,屆時地球上便再不能看到日全食了。

Although much of the world was not able to see it , the solar eclipse that passed over the earth on friday was what astronomers call a hybrid eclipse that only occurs every 18 years (盡管世界上大部分人無法看到,但周五繞經地球的日蝕即是天文學家所謂18年才出現一次的混合日蝕。 )

Maya priests prophesied the total solar eclipse of july 11 , 1991 would herald two life altering events for humankind : cosmic awareness and earth changes 公元755年,瑪雅祭司預言了1991年7月11日的整個日蝕會傳達兩種生命的意義,是為人類改變的事件:宇宙意識和地球的轉變。

Only observers near the center of the dark circle see a total solar eclipse - others see a partial eclipse where only part of the sun appears blocked by the moon 只有在離黑圈的中心很近才能看見完全的日食-其余的人只能看見部分日食由于太陽看起來只是遮住了月亮的一部分。

Phenomena involving brighter celestial bodies such as solar eclipses , lunar eclipses and moon phases can be recorded by stationary method with proper exposure time 一些較光亮的天象如日食月食或月球的盈虧都可以用固定方法拍攝,只不過曝光的時間需要小心掌握。

If the moon is only in the penumbra , we usually say that there is no eclipse . if you were on the moon at that time , you would see a partial solar eclipse 假若月球只是進入地球的半影,通常我們不會當它是月食,如果這時你有幸在月球上,你會看到一次日偏食現象。

According to phenomena observed during total solar eclipse , it can be pointed out that the velocity of gravitational field wave is equal to the velocity of light in vacuo 摘要據日全食時的現象能夠得出:在真空中,引力波的傳播速度和光波的傳播速度相等。

During solar eclipse , if the angular size of the moon is larger than that of the sun , the sun will be totally covered , resulted in total solar eclipse 日食solar eclipse時太陽被月球所侵蝕與及月食lunar eclipse時月球被地影所蠶食的意思亦顯而易見。

The next solar eclipse observable in hong kong will occur on 1 august 2008 . it will be a total eclipse but only be visible as a partial eclipse in hong kong 下一次可以在本港見到的日食將在2008年8月1日出現,是一次日全食,但在香港只可看見日偏食。

Although the next solar eclipse will occur this october , astronomers say the next uniquely hybrid eclipse will not occur again until 2023 雖然今年十月還會出現下一個日蝕,但天文學家說,這種獨特的混合日蝕要等到2023年才會再出現。

However , during a total solar eclipse , when the sun is fully blocked by the moon , you can photograph it with a telephoto lens or even a telescope 但在日全食出現時,即太陽完全被月球遮蓋著,則可利用長焦距鏡頭或望遠鏡進行拍攝。

Shicha algorithm of parallax theory plays an important role in solar eclipse theory because it is one of the major algorithms in solar solar eclipse theory 摘要日食時差算法是日食計算中的核心算法,在日食理論中占有重要地位。

Since sunlight is very strong , do not attempt to take photographs of the sun , partial or annular solar eclipse without using a professional filter 由于陽光十分猛烈,如沒有專業的減光設備,切勿嘗試拍攝太陽日偏食或日環食。

His significant accomplishments include the successful prediction of a solar eclipse , publishing his own almanac , and the surveying of washington , d . c 他的杰出成就包括了成功預測日蝕、出版自制年歷、丈量華盛頓等。

A solar eclipse occurs when the moon is directly in line between the sun and earth , so that the moon s shadow falls on part of the earth 兩個字在描述太陽的光芒被月球掩蓋或月球走進地球的陰影時是相通的。

If you reverse the roles of the moon and the earth in the above paragraphs , we will get solar eclipses instead of the lunar eclipses 若將上一段文字中月球和地球的角色互換便會發生日食。最普遍的日食是
