2023年10月19日 A Sunrise at Sunset Point Image Credit & Copyright: Martin Ratcliffe Explanation: This timelapse series captured on October 14 is set against the sunrise view from Sunset Point, Bryce Canyon, planet Earth. Of course on that date the New Moon caught up with the Sun in the canyon’s morning skies. Local temperatures fell as the Moon’s shadow swept across the high altitude scene and the brilliant morning sunlight became a more subdued yellow hue cast over the reddish rocky landscape. In the timelapse series, images were taken at 2 minute intervals. The camera and solar filter were fixed to a tripod to follow the phases of the annular solar eclipse.

2023年10月16日 Eclipse Rings Image Credit & Copyright: Jerry Zhang (left), Baolong Chen (photographer) & Amber Zhang (right) Explanation: She knew everything but the question. She was well aware that there would be a complete annular eclipse of the Sun visible from their driving destination: Lake Abert in Oregon. She knew that the next ring-of-fire eclipse would occur in the USA only in 16 more years, making this a rare photographic opportunity. She was comfortable with the plan: that she and her boyfriend would appear in front of the eclipse in silhouette, sometimes alone, and sometimes together. She knew that the annular phase of this eclipse would last only a few minutes and she helped in the many hours of planning. She could see their friend…

2023年10月5日 Ring of Fire over Monument Valley Image Credit & Copyright: Tunc Tezel (TWAN) Explanation: Tracking along a narrow path, the shadow of a new moon will race across North, Central, and South America, on October 14. When viewed from the shadow path the apparent size of the lunar disk will not quite completely cover the Sun though. Instead, the moon in silhouette will appear during the minutes of totality surrounded by a fiery ring, an annular solar eclipse more dramatically known as a ring of fire eclipse. This striking time lapse sequence from May of 2012 illustrates the stages of a ring of fire eclipse. From before eclipse start until sunset, they are seen over the iconic buttes of planet Earth’s Monument Valley. Remarkably,…

2022年10月27日 Sunset, Moonset, Taj Mahal Image Credit & Copyright: Neelam and Ajay Talwar (TWAN) Explanation: On October 25th, Sun and New Moon set together as seen from Agra, India. Their close conjunction near the western horizon, a partial solar eclipse, was captured in this elevated view in hazy skies near the solitary dome of the Taj Mahal. Of course, the partial solar eclipse was also seen from most of Europe, northern Africa, the Middle East, and western parts of Asia. This eclipse was the last of two solar eclipses (both partial eclipses) in 2022. But the next Full Moon will slide through planet Earth’s shadow on November 7/8, in a total lunar eclipse. Tomorrow’s picture: comet’s return 日落（月落）泰姬玛哈陵 图像提供与版权: Neelam and Ajay Talwar（TWAN） 说明: 10月25日，从印度.阿格拉市看出去，太阳和新月同时西落。两者在西方地平线附近的近合，带来了悬在泰姬玛哈陵圆顶上方朦胧天空中的日偏食。当然，这次的日偏食，在大部分的欧洲地区、北非、中东、和亚洲西部也得见。而这次日食，是2022年2次日食（均为偏食）中的最后一次。不过，11月7/8日的下轮满月将滑入地球的影子里带来月全食的景观。…

2022年7月25日 Find the New Moon Image Credit & Copyright: Mohamad Soltanolkotabi Explanation: Can you find the Moon? This usually simple task can be quite difficult. Even though the Moon is above your horizon half of the time, its phase can be anything from crescent to full. The featured image was taken in late May from Sant Martí d’Empúries, Spain, over the Mediterranean Sea in the early morning. One reason you can’t find this moon is because it is very near to its new phase, when very little of the half illuminated by the Sun is visible to the Earth. Another reason is because this moon is near the horizon and so seen through a long path of Earth’s atmosphere — a path which dims the…

2021年01月07日 Total Solar Eclipse 2020 Image Credit & Copyright: Miloslav Druckmuller, Andreas Moller, (Brno University of Technology), Explanation: Along a narrow path crossing southern South America through Chile and Argentina, the final New Moon of 2020 moved in front of the Sun on December 14 in the year’s only total solar eclipse. Within about 2 days of perigee, the closest point in its elliptical orbit, the New Moon’s surface is faintly lit by earthshine in this dramatic composite view. The image is a processed composite of 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 with planet-sized prominences at the Sun’s edge, an enormous coronal mass…
