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…
