2023年09月17日:日环食期间被放大的月球山峰-(Moon Mountains Magnified during Ring of Fire Eclipse)
2023年09月17日:日环食期间被放大的月球山峰-(Moon Mountains Magnified during Ring of Fire Eclipse)--原图下载{mtitle title="日环食期间被放大的月球山峰"/}Credit & Copyright: Wang Letian (Eyes at Night)说明: 在这张摄于日食期间的组合影像里,这些暗纹是什么?它们是月缘山峰的倒转影子。最中间摄于中国.厦门的照片,则呈现了月亮中心与太阳中心重合的食甚阶段。在此例日食里,月亮离地球太远,因此无法遮住整个日盘。阳光得以从月亮的边缘透过来,形成火之环的景观。此外在这个影像系列里,于环食启始的食既和结束的生光阶段,阳光也会从月谷漏出来。随着月亮从左到右移过日盘,只有较高的月缘山峰,才能挡住阳光。因此这些暗纹,其实是月缘山峰投射出的扭曲、倒转及放大影子。影像中的亮区称为倍里珠。在2020年时,只有在东半球的狭窄食带内,才能见到这例日环食的完整过程。在下个月,于穿过北美洲及南美洲的狭窄的食带里,可再次见到另一个日环食。然后在明年4月,北美洲可见到日全食。{lamp/}原文:{mtitle title="Moon Mountains Magnified during Ring of Fire Eclipse"/}Credit & Copyright: Wang Letian (Eyes at Night)Explanation: What are those dark streaks in this composite image of a solar eclipse?They are reversed shadows of mountains at the edge of the Moon. The center image, captured from Xiamen, China, has the Moon's center directly in front of the Sun's center.The Moon, though, was too far from the Earth to completely block the entire Sun. Light that streamed around the edges of the Moon is called a ring of fire.Images at each end of the sequence show sunlight that streamed through lunar valleys. As the Moon moved further in front of the Sun, left to right, only the higher peaks on the Moon's perimeter could block sunlight. Therefore, the dark streaks are projected, distorted, reversed, and magnified shadows of mountains at the Moon's edge. Bright areas are called Baily's Beads.Only people in a narrow swath across Earth's Eastern Hemisphere were able to view this full annular solar eclipse in 2020.Next month, though, a narrow swath crossing both North and South Americawill be exposed to the next annular solar eclipse.And next April, a total solar eclipse will be visible across North America.

2021年01月07日:2020年日全食-(Total Solar Eclipse 2020)
2021年01月07日:2020年日全食-(Total Solar Eclipse 2020)--原图下载{mtitle title="2020年日全食"/}Image Credit &Copyright:Miloslav Druckmuller,Andreas Moller,(Brno University of Technology),说明: 12月14日,在南美洲智利到阿根廷的一道狭窄带上,2020年最后一轮新月掩过太阳的前方,带来2020年唯一的日全食。在这幅精采的组合影像里,离椭圆轨道最近地球的近地点2天的新月,其表面受到地照光微微照亮。而这幅影像,则组合自55张经过校正、曝光时间介于1/640至3秒的照片。影像除了呈现全食阶段大範围的亮度变化,也记录了暗淡的月表、背景恒星、太阳边缘大小与行星相当的日珥、庞大的日冕物质抛射事件、及通常受太阳炫光遮掩而不得见的流泛日冕。如仔细检视,还可见到一颗难逃灭亡命运的克罗伊泽族掠日彗星C/2020 X3 SOHO,从左下方大约7点钟的方位向内飞掠。在2021年的6月10日,追日食者可见到日环食。不过,如想见到2021年唯一的日全食,得再等到12月4日。届时可见的区域,是在南极洲的一道狭窄食带上。{lamp/}原文:{mtitle title="Total Solar Eclipse 2020"/}Image Credit &Copyright:Miloslav Druckmuller,Andreas Moller,(Brno University of Technology),Explanation: Along a narrow pathcrossing southern South America through Chileand Argentina, the final New Moon of 2020moved in front of the Sun on December 14 in the year's onlytotal solar eclipse.Within about 2 days of perigee, the closest point in its ellipticalorbit, the New Moon's surface is faintlylit by earthshinein this dramatic composite view.The image is a processed compositeof 55 calibrated exposures ranging from 1/640 to 3 seconds.Covering a large range in brightness during totality,it reveals the dim lunar surface and faint background stars,along withplanet-sizedprominences at the Sun's edge, an enormouscoronal mass ejection,and sweeping coronal structures normally hidden in the Sun's glare.Look closelyfor an ill-fated sungrazing Kreutz family comet(C/2020 X3 SOHO)approaching from the lower left, at about the 7 o'clock position.In 2021 eclipse chasers will see an annular solar eclipse coming upon June 10.They'll have to wait until December 4 for the only totalsolar eclipse in 2021 though.That eclipse will betotal along a narrow path crossing the southernmostcontinent of Antarctica.

A total solar eclipse will be visible at the bottom of the world near the end of this year.

2019年07月18日:-()--原图下载{mtitle title=""/}Image Credit: Norbert Span说明: 7月16日阿波罗11号发射的50周年时,月亮以全球大部分地区可见的月食献上祝贺。如同上面这张影像所示,当时部分的月盘沈浸在地球黝黑红化的本影里。而在接近最大食分的期间,月亮沿着这座山的稜线滑落。这幅呈现奥地利.因斯布鲁克市南方崎岖泰罗宁山脉夜景的影像,摄于月出之后,同时也记录座落在稜线上,点着明亮灯火的通讯塔。交食现象通常不是独立事件,例如在这个满月的偏食事件发生之后,紧接着七月的第二个新月,就为我们带来了日全食事件。{lamp/}原文:{mtitle title=""/}Image Credit: Norbert SpanExplanation: On July 16 the Moon celebrated the 50th anniversary of thelaunch of Apollo 11with a lunar eclipse visible from much of planet Earth.In this view part of the lunar disk is immersedin Earth's dark, reddenedumbral shadow.Near the maximum eclipse phase,it just touches down along a mountain ridge.The rugged Tyrolean nightscape was recorded after moonrise southof Innsbruck, Austria with a dramatically lit communication toweralong the ridgeline.Of course eclipses rarely travel alone.This partial lunar eclipsewas at the Full Moon following July 2nd's New Moon and totaleclipse of the Sun.

2018年08月27日:汽球上见到的日全食影子-(Total Solar Eclipse Shadow from a Balloon)
2018年08月27日:汽球上见到的日全食影子-(Total Solar Eclipse Shadow from a Balloon)--原图下载{mtitle title="汽球上见到的日全食影子"/}Image Credit: Kuaray Project, NASA Eclipse Ballooning Project, Brasilia Astronomy Club, Montana State U.说明: 2017年美国大日食期间,你人在何处?离上星期的一年前,北美洲有超过1亿人走出户外,去观赏日偏食 ,而在同一期间里,有超过1千万位在美国各地的人们,见到了太阳完全消失在月盘后头的日全食。据估据,有百分之八十八的美国成年人,要么直接要么透过转播见到此次日食。此次日食,是人类历史上有最多影像记录的事件之一,日食影像 的摄影平台涵盖一些颇不寻常的地点,甚至包括飘流在地球平流层里的汽球。这批总数约50颗的汽球,是美国航太总署日食探空汽球计画的一部分。上面的主题照片,是由从爱达荷州释放的无人汽球上拍摄的360环景影片的一个定格,参与汽球释放者包括巴西的学生及美国航太总署和蒙大拿州立大学的人员。在影像里,可见到月球的影子 掠过下方的大地。虽然全食阶段持续不到3分钟,但许多亲眼目睹者 ,可能会终生难忘。许多北美洲的居民在2024年,有机会再次见到日全食。{lamp/}原文:{mtitle title="Total Solar Eclipse Shadow from a Balloon"/}Image Credit: Kuaray Project, NASA Eclipse Ballooning Project, Brasilia Astronomy Club, Montana State U.Explanation: Where were you during the Great American Eclipse of 2017? A year ago last week, over 100 million of people in North America went outside to see a partial eclipse of the Sun, while over ten million drove across part of the USA to see the Sun completely disappear behind the Moon -- a total solar eclipse.An estimated 88 percent of American adults saw the eclipse either personally or electronically.One of the better photographed events in human history, images from the eclipse included some unusual vistas, such as from balloons floating in the Earth's stratosphere.About fifty such robotic balloons were launched as part of NASA's Eclipse Ballooning project.Featured is a frame taken from a 360-degree panoramic video captured by one such balloon set aloft in Idaho by students from Brazil in conjunction with NASA and Montana State University.Pictured, the dark shadow of the Moon was seen crossing the Earth below. Although the total eclipse lasted less than three minutes, many who saw it may remember it for a lifetime.Many North Americans will get a another chance to experience a total solar eclipse in 2024.

2017年08月19日:1979年日全食-(Total Solar Eclipse of 1979)
2017年08月19日:1979年日全食-(Total Solar Eclipse of 1979)--原图下载{mtitle title="1979年日全食"/}Image Credit &Copyright:Jimmy Westlake (ColoradoMountain College)说明:这张摄于1979年2月26日的长焦镜头影像,记录了地球.加拿大.曼尼托巴.里弗顿寒冷清朗天空中,日冕环拱在新月剪影周围的景观。这个发生在38年前的事件,是在美国附近所见到的最后一次日全食。当时狭窄的全食带掠过美国西北角的华盛顿州、奥勒冈州、爱达华州、蒙大拿州和北达科达州,然后再穿过加拿大的萨斯喀彻温省、曼尼托巴省、安大略省和魁北克省。接续在即将到来2017年8月21日从西岸横贯到东岸的日全食之后,在2023年10月14日美国本土从北加州到佛罗里达州一带,可见到日环食。然后在2024年4月8日会再出现一次日全食,全食带将会切过美国本土从德州到缅因州等13个州。{lamp/}原文:{mtitle title="Total Solar Eclipse of 1979"/}Image Credit &Copyright:Jimmy Westlake (ColoradoMountain College)Explanation: From cold, clear skies over Riverton, Manitoba, Canada, planet Earth,the solar corona surrounds the silhouette of the New Moon in thistelescopic snapshot of the total solar eclipse of February 26, 1979.Thirty eight years ago, it wasthe last totalsolar eclipse visible from the contiguous United States.The narrow path of totality ran through the northwesternstates of Washington, Oregon, Idaho, Montana, and North Dakotabefore crossing into Canadian provinces Saskatchewan, Manitoba,Ontario and Quebec.Following the upcomingAugust 21, 2017total solar eclipse crossing the U.S. from coast to coast,an annular solar eclipse will be seen inthe continental United States on October 14, 2023,visible along a route from Northern California to Florida.Then,thenext total solar eclipse to touch thecontinental U.S. will track across 13 states fromfrom Texas to Maine on April 8, 2024.
