树荫里的日食
2023年10月15日 An Eclipse Tree Image Credit & Copyright: Shawn Wyre Explanation: Yes, but can your tree do this? If you look closely at the ground in the featured image, you will see many images of yesterday’s solar eclipse — created by a tree. Gaps between tree leaves act like pinhole lenses and each create a small image of the partially eclipsed Sun visible in the other direction. The image was taken in Burleson, Texas, USA. Yesterday, people across the Americas were treated to a partial eclipse of the Sun, when the Moon moves in front of part of the Sun. People in a narrow band of Earth were treated to an annular eclipse, also called a ring-of-fire eclipse, when the Moon becomes completely engulfed by…
扭曲的日出带食
2023年10月9日 A Distorted Sunrise Eclipse Image Credit & Copyright: Elias Chasiotis Explanation: Yes, but have you ever seen a sunrise like this? Here, after initial cloudiness, the Sun appeared to rise in two pieces and during a partial eclipse in 2019, causing the photographer to describe it as the most stunning sunrise of his life. The dark circle near the top of the atmospherically-reddened Sun is the Moon — but so is the dark peak just below it. This is because along the way, the Earth’s atmosphere had a layer of unusually warm air over the sea which acted like a gigantic lens and created a second image. For a normal sunrise or sunset, this rare phenomenon of atmospheric optics is known as the Etruscan…
飞机、云、月亮、黑子与太阳
2023年10月8日 Plane, Clouds, Moon, Spots, Sun Image Credit & Copyright: Doyle and Shannon Slifer Explanation: What’s that in front of the Sun? The closest object is an airplane, visible just below the Sun’s center and caught purely by chance. Next out are numerous clouds in Earth’s atmosphere, creating a series of darkened horizontal streaks. Farther out is Earth’s Moon, seen as the large dark circular bite on the upper right. Just above the airplane and just below the Sun’s surface are sunspots. The main sunspot group captured here, AR 2192, was in 2014 one of the largest ever recorded and had been crackling and bursting with flares since it came around the edge of the Sun a week before. This show of solar silhouettes was…
活跃太阳的偏食
2022年11月2日 A Partial Eclipse of an Active Sun Video Credit: Ralf Burkart; h/t Maciej Libert (AG) Explanation: Watch for three things in this unusual eclipse video. First, watch for a big dark circle to approach from the right to block out more and more of the Sun. This dark circle is the Moon, and the video was made primarily to capture this partial solar eclipse last week. Next, watch a large solar prominence hover and shimmer over the Sun’s edge. A close look will show that part of it is actually falling back to the Sun. The prominence is made of hot plasma that is temporarily held aloft by the Sun’s changing magnetic field. Finally, watch the Sun’s edge waver. What is wavering is a…
日落（月落）泰姬玛哈陵
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。…
来自食日的火红云隙光
2022年5月30日 Red Crepuscular Rays from an Eclipse Image Credit & Copyright: Fefo Bouvier Explanation: What’s happening behind that island? Things both expected and unexpected. Expected, perhaps, the pictured rays of light — called crepuscular rays — originate from the Sun. Unexpected, though, the Sun was being partially eclipsed by the Moon at the time — late last month. Expected, perhaps, the Sun’s rays are quite bright as they shine through gaps in below-horizon clouds. Unexpected, though, the crepuscular rays are quite red, likely the result an abundance of aerosols in Earth’s atmosphere scattering away much of the blue light. Expected, with hope, a memorable scene featuring both the Moon and the Sun, superposed. Unfortunately, from this location — in Uruguay looking toward Argentina — clouds…
阿根廷上空的日偏食
2022年5月2日 Partial Solar Eclipse over Argentina Image Credit & Copyright: Aixa Andrada Explanation: What’s happened to the Sun? Two days ago, parts of South America were treated to a partial solar eclipse — where the Moon blocked out part of the Sun. The featured image shows an image of the partially eclipsed Sun through clouds as it was setting over Patagonia, Argentina. In the tilted image, Earth is toward the right. During the eclipse, the Moon moved partly between Earth and the Sun. Although a visually impressive sight, the slight dimming of surroundings during this partial eclipse was less noticeable than dimming created by a thick cloud. In about two weeks, all of South America and part of North America will experience a total lunar…
水面上的日食
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…
