2023年09月10日:美国新墨西哥州上空的日环食-(An Annular Solar Eclipse over New Mexico)
2023年09月10日:美国新墨西哥州上空的日环食-(An Annular Solar Eclipse over New Mexico)--原图下载{mtitle title="美国新墨西哥州上空的日环食"/}Credit & Copyright: Colleen Pinski说明: 这家伙在做什么?2012年日环食的可见区域,为穿过北太平洋和美国本土数个西部州的狭窄全食带。在日环食期间,月亮离地球太远而无法完全遮住太阳,因此日盘会从月盘的边缘露出来,形成火之环的景观。为了要记录这种难得的太阳事件,一位不嫌麻烦的的摄影者,从亚利桑那州开车到新墨西哥州,寻找完美的观测地点。在架好设备后,食日正落向半公里外的山脊后方,而一位不知情者刚好走入视野。虽然虽然摄影者为外加的人文元素而心怀感激,但他从未得知这位以剪影之姿入镜者的身份。乍看之下,这位老兄好像手持一个用来观赏这次日食的圆形器物。这幅影像是在2012年5月20日当地时间7:36 pm,摄于美国.新墨西哥州.阿布奎基市的一座公园内。下个月的10月14日将再出现另一例日环食,而如果天空清朗的话,此事件可见的区域为穿过北美洲与南美洲的狭窄食带。在此同时,这二个洲无云遮蔽地区的其他住民可见到日偏食。{lamp/}原文:{mtitle title="An Annular Solar Eclipse over New Mexico"/}Credit & Copyright: Colleen PinskiExplanation: What is this person doing? In 2012, an annular eclipse of the Sun was visible over a narrow path that crossed the northern Pacific Ocean and several western US states. In an annular solar eclipse, the Moon is too far from the Earth to block out the entire Sun, leaving the Sun peeking out over the Moon's disk in a ring of fire. To capture this unusual solar event, an industrious photographer drove from Arizona to New Mexico to find just the right vista.After setting up and just as the eclipsed Sun was setting over a ridge about 0.5 kilometers away, a person unknowingly walked right into the shot.Although grateful for the unexpected human element, the photographer never learned the identity of the silhouetted interloper.It appears likely that the person is holding a circular device that would enable them to get their own view of the eclipse.The shot was taken at sunset on 2012 May 20 at 7:36 pm local time from a park near Albuquerque. Next month, on October 14, a different narrow swath across North and South America will be exposed to a different annular solar eclipse, if the sky is clear.Simultaneously, cloud-free observers almost anywhere on either continent will be able to see a partial solar eclipse.

However, almost all of Asia with a clear sky will be able to see, tomorrow, at the least, a partial solar eclipse.

2018年04月30日:日全食日冕的高动态範围影像-(Total Solar Eclipse Corona in HDR)
2018年04月30日:日全食日冕的高动态範围影像-(Total Solar Eclipse Corona in HDR)--原图下载{mtitle title="日全食日冕的高动态範围影像"/}Image Credit & Copyright: Nicolas Lefaudeux说明: 美国大日食到底有多精采呢?这张高动态範围主题影像证明,它或许比我们所知的还要更精采。在去年的8月21日,沿着一道横贯美国的狭窄路径上,月亮 挡在太阳前方达数分钟之久。虽然这个事件,是人类历史上拥有最多影像记录的事件之一,但是上面这张影像,因为需要极大量的数位处理,直到最近才得以完成,并且呈现了有史以来拍到的最细緻日冕景观之一。由极端炽热的气体聚成的日冕,只有在日全食期间肉眼才得见。这张主题影像,总共整合了70多幅曝光时间长短不一的照片。这系列的互补式高动态範围影像,获得足够的细节,让我们得以见到日冕的运动。这批影像摄于美国.奥勒冈州.Unity当地早晨,以确保有稳定的大气视宁度。地球上可见的下一次日全食,将发生在2019年7月,然而下一个整个北美洲和美国都看得到的日全食,得再等到2024年4月。{lamp/}原文:{mtitle title="Total Solar Eclipse Corona in HDR"/}Image Credit & Copyright: Nicolas LefaudeuxExplanation: How great was the Great American Eclipse?The featured HDR image shows it to be perhaps greater than we knew.On August 21 of last year, the Moon blocked the Sun for a few minutes along a narrow path across the USA.Although one of the most photographed events in human history, this image -- only recently completed after an extraordinary amount of digital processing -- shows one of the most detailed depictions of a solar corona ever taken. Composed of extremely hot gas, the solar corona is only visible to the unaided eye during a total solar eclipse.The featured image combined over 70 images of different time exposures. The series of complementary HDR images recovered enough detail to see motion of the solar corona.The images were taken in Unity, Oregon in the morning to get steady atmospheric seeing conditions.The next total solar eclipse visible on Earth will be in 2019 July, while the next one visible across North America and the USA will occur in 2024 April.

2017年01月31日:该到何处去看美国日食-(Where to See the American Eclipse)
2017年01月31日:该到何处去看美国日食-(Where to See the American Eclipse)--原图下载{mtitle title="该到何处去看美国日食"/}Image Credit: Jay Anderson; Data: MODIS Satellite, NASA's GSFC说明: 你计划去观赏8月21日的美国日食吗?在那天的日出后的数小时,在切过美国的一道狭窄路径上,可见到相对罕见的日全食。不在这个带状区内的人,则会看到日偏食。虽然有些美国人就住在全食带之内,但是,一定有更多人会规划开车前去这个带状区。不过观赏日月食,有时会受到云层的干扰。所以为了增加视野清朗的机会,你不妨参考这幅主题图片,然后找个历史记录上常是蓝天的地点,以免全食阶段受到乌云的遮蔽。因为大部分的美国人拥有照相功能的智慧手机,这次的美国日食,可能会成为世界历史上最广被拍摄的天文事件。{lamp/}原文:{mtitle title="Where to See the American Eclipse"/}Image Credit: Jay Anderson; Data: MODIS Satellite, NASA's GSFCExplanation: Are you planning to see the American Eclipse on August 21?A few hours after sunrise, a rare total eclipse of the Sun will be visible along a narrow path across the USA.Those only near the path will see a partial eclipse. Although some Americans live right in path of totality, surely many more will be able to get there after a well-planned drive. One problem with eclipses, though, is that clouds sometimes get in the way. To increase your clear-viewing odds, you might consult the featured map and find a convenient destination with a historically low chance (more blue) of thick clouds overhead during totality.Given the large fraction of Americans carrying camera-equipped smartphones, this American Eclipse may turn out to be the most photographed event in the history of the world.

2016年08月31日:美国.新墨西哥州上空的日环食 -(Annular Solar Eclipse over New Mexico)
2016年08月31日:美国.新墨西哥州上空的日环食 -(Annular Solar Eclipse over New Mexico)--原图下载{mtitle title="美国.新墨西哥州上空的日环食 "/}Image Credit & Copyright: Colleen Pinski说明: 这个人在做什么?2012年的日环食,可见的区域在通过北太平洋及数个美国西部州的狭窄食带上。日环食之所以发生,是因为月亮离地球太远而无法遮住整个太阳,因此太阳从月盘的边缘露出来形成一圈火之环。为了捕捉这个不寻常的日食现象,一位勤快的摄影者从美国的亚利桑那州开车到新墨西哥州,去寻找合适的视野。在架好相机之后,食日正在向2.5公里外的山脊西沉之时,一位不知情的人士走入场景里。这个人看似拿着一个圆形装置让他得以观赏日食。虽然拍摄者很感谢这份意外纳入的人文元素,但是这位剪影中人,身份一直不明。这幅摄于美国.新墨西哥州.阿尔伯克基市附近一座公园内的影像,拍摄的时间是2012年5月20日当地时间下午7:36。你认识当时正在看日食的这个人吗?明天将可见到另一次日环食,此次的食带将划过非洲及马达加斯加。{lamp/}原文:{mtitle title="Annular Solar Eclipse over New Mexico"/}Image Credit & Copyright: Colleen PinskiExplanation: What is this person doing?
