2023年9月17日 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…

2023年9月10日 An Annular Solar Eclipse over New Mexico Credit & Copyright: Colleen Pinski Explanation: 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…

2021年06月18日 Devil Horns from a Ring of Fire Image Credit & Copyright: Madhup Rathi Explanation: Atmospheric refraction flattened the solar disk and distorted its appearance in this telescopic view of an Atlantic sunrise on June 10. From Belmar, New Jersey on the US east coast, the scene was recorded at New Moon during this season’s annular solar eclipse. The Moon in partial silhouette gives the rising Sun its crescent shape reminding some of the horns of the devil (or maybe a flying canoe …). But at its full annular phase this eclipsed Sun looked like a ring of fire in the heavens. June’s annular solar eclipse followed on the heels of the total lunar eclipse of late May’s Full Moon. Of course, that total lunar…

2021年06月12日 Eclipse on the Water Image Credit & Copyright: Elliot Severn Explanation: Eclipses tend to come in pairs. Twice a year, during an eclipse season that lasts about 34 days, Sun, Moon, and Earth can nearly align. Then the full and new phases of the Moon separated by just over 14 days create a lunar and a solar eclipse. Often partial eclipses are part of any eclipse season. But sometimes the alignment at both new moon and full moon phases during a single eclipse season is close enough to produce a pair of both total (or a total and an annular) lunar and solar eclipses. For this eclipse season, the New Moon following the Full Moon’s total lunar eclipse on May 26 did produce an…

2021年06月11日 Eclipse Flyby Image Credit & Copyright: Zev Hoover, Christian Lockwood, and Zoe Chakoian Explanation: On June 10 a New Moon passed in front of the Sun. In silhouette only two days after reaching apogee, the most distant point in its elliptical orbit, the Moon’s small apparent size helped create an annular solar eclipse. The brief but spectacular annular phase of the eclipse shows a bright solar disk as a ring of fire when viewed along its narrow, northerly shadow track across planet Earth. Cloudy early morning skies along the US east coast held gorgeous views of a partially eclipsed Sun though. Rising together Moon and Sun are captured in a sequence of consecutive frames near maximum eclipse in this digital composite, seen from Quincy…

2020 June 27 Eclipse under the ISS Image Credit: NASA ISS Expedition 63 Explanation: The dark shadow of the New Moon reached out and touched planet Earth on June 21. A high definition camera outside the International Space Station captured its passing in this snapshot from low Earth orbit near the border of Kazakhstan and China. Of course those along the Moon’s central shadow track below could watch the much anticipated annular eclipse of the Sun. In the foreground a cargo spacecraft is docked with the orbital outpost. It’s the H-II Transfer Vehicle-9 from JAXA the Japan Aerospace Exploration Agency. Gallery: Notable images of the Annular Solar Eclipse of 2020 June submitted to APOD Tomorrow’s picture: moons and shadows 国际空间站下方的月影 影像提供:NASA ISS Expedition 63 说明:在6月21日,向太空伸展的新月影子落到地球上。而挂在国际太空站外头的高画质摄影机,从低地球轨道上,恰好拍下这幅影像捕捉到影子掠过哈萨克斯坦共和国和中国的边境。想当然耳,在月亮影子中心掠过地区的人们,得以见到引颈翘望的日环食。影像的前景,可见到一艘停泊在这个轨道前哨站的补给太空船。它是日本宇宙航空研究开发机构(JAXA),所派遗的H-II第8号补给船。…

2020 June 26 Eclipse under the Bamboo Image Credit & Copyright: Somak Raychaudhury (Inter-University Centre for Astronomy & Astrophysics) Explanation: Want to watch a solar eclipse safely? Try looking down instead of up, though you might discover you have a plethora of images to choose from. For example, during the June 21st solar eclipse this confusing display appeared under a shady bamboo grove in Pune, India. Small gaps between close knit leaves on the tall plants effectively created a network of randomly placed pinholes. Each one projected a separate image of the eclipsed Sun. The snapshot was taken close to the time of maximum eclipse in Pune when the Moon covered about 60 percent of the Sun’s diameter. But an annular eclipse, the Moon in…

2020 June 25 Eclipse Street, Hong Kong Image Credit & Copyright: Gary Chan Explanation: On June 21 an annular solar eclipse came soon after the solstice and our fair planet’s northernmost sunset for 2020. At maximum eclipse, the New Moon in silhouette created a ring of fire visible along a narrow path at most 85 kilometers wide. The annular eclipse path began in central Africa, crossed south Asia and China, and ended over the Pacific Ocean. But a partial eclipse of the Sun was visible over a much broader region. In Hong Kong, this busy section of Jordan Street looks to the northwest, well-aligned with the track of the near solstice afternoon Sun. The street level view was composited with an eclipse sequence made with…

2020 June 22 Moon Mountains Magnified during Ring of Fire Eclipse Image Credit & Copyright: Wang Letian (Eyes at Night) Explanation: What are those dark streaks in this composite image of yesterday’s 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 all of 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…

2020 June 15 A Ring of Fire Sunrise Solar Eclipse Video Credit: Colin Legg & Geoff Sims; Music: Peter Nanasi Explanation: What’s rising above the horizon behind those clouds? It’s the Sun. Most sunrises don’t look like this, though, because most sunrises don’t include the Moon. In the early morning of 2013 May 10, however, from Western Australia, the Moon was between the Earth and the rising Sun. At times, it would be hard for the uninformed to understand what was happening. In an annular eclipse, the Moon is too far from the Earth to block the entire Sun, and at most leaves a ring of fire where sunlight pours out around every edge of the Moon. The featured time-lapse video also recorded the eclipse…
