烟火与超级月亮

2023年7月6日 Fireworks vs Supermoon Image Credit & Copyright: Michael Seeley Explanation: On July 4, an almost Full Moon rose in planet Earth’s evening skies. Also known as a Buck Moon, the full lunar phase (full on July 3 at 11:39 UTC) was near perigee, the closest point in the Moon’s almost monthly orbit around planet Earth. That qualified this July’s Full Moon as a supermoon, the first of four supermoons in 2023. Seen from Cocoa Beach along Florida’s Space Coast on July 4, any big, bright, beautiful Full Moon would still have to compete for attention though. July’s super-moonrise was captured here against a super-colorful fireworks display. Tomorrow’s picture: pixels in space 烟火与超级月亮 影像版权与提供: Michael Seeley 说明: 在7月4日，一轮几乎满相的月亮在地球的夜空中升起。亦名为雄鹿月的这轮明月，满相点（7月3日11:39 UTC）在近地点附近，也就是说，在为期将近一个月的绕地轨道上，月亮来到了最接近地球的位置。所以今年7月的满月是超级月亮，这也是2023年4个超级月亮中的第一个。于7月4日，从佛罗里达州太空海岸的可可亚海滩看出去，这轮美丽的满月尽管大又亮，却无法占尽风采。因为在拍摄这轮超级月亮东升之时，前景有无比缤纷的烟花表演。 （Buck Moon 雄鹿月） 明日的图片: pixels in…

2023年1月6日 Moon O’Clock 2022 Image Credit & Copyright: Niveth Kumar Explanation: The first Full Moon of 2023 is in the sky tonight opposite the Sun at 23:08 UTC. Big and beautiful, the Moon at its brightest phase should be easy to spot. Still, for quick reference images captured near the times of all the full moons of 2022 are aranged in this dedicated astro-imaging project from Sri Lanka, planet Earth. The day, month, and a traditional popular name for 2022’s twelve full moons are given in the chart. The apparent size of each full moon depends on how close the full lunar phase is to perigee or apogee, the closest or farthest point in the Moon’s elliptical orbit. Like the 2022 Wolf Moon at the…

2022年10月1日 Lunation Matrix Image Credit & Copyright: Tunc Tezel (TWAN) Explanation: Observe the Moon every night and you’ll see its visible sunlit portion gradually change. In phases progressing from New Moon to Full Moon to New Moon again, a lunar cycle or lunation is completed in about 29.5 days. Top left to bottom right, this 7×4 matrix of telescopic images captures the range of lunar phases for 28 consecutive nights, from the evening of July 29 to the morning of August 26, following an almost complete lunation. No image was taken 24 hours or so just after and just before New Moon, when the lunar phase is at best a narrow crescent, close to the Sun and really hard to see. Finding mostly clear Mediterranean…

2022年7月15日 Lubovna Full Moon Petr Horalek / Institute of Physics in Opava Explanation: On July 13 this well-planned telephoto view recorded a Full Moon rising over Lubovna Castle in eastern Slovakia. The photographer was about 3 kilometers from the castle walls and about 357,000 kilometers from this Full Moon near perigee, the closest point in its elliptical orbit. Known to some as supermoons, full moons near perigee are a little brighter and larger in planet Earth’s sky when compared to full moons that occur near the average lunar distance of around 384,000 kilometers. Of course any Full Moon near the horizon can show the effects of refraction over a long sight-line through dense clear atmosphere. In this image, atmospheric refraction creates the slight green flash…

2022年6月16日 Strawberry Supermoon from China Image Credit & Copyright: Jeff Dai (TWAN) Explanation: There are four Full Supermoons in 2022. Using the definition of a supermoon as a Full Moon near perigee, that is within at least 90% of its closest approach to Earth in a given orbit, the year’s Full Supermoon dates are May 16, June 14, July 13, and August 12. Full Moons near perigee really are the brightest and largest in planet Earth’s sky. But size and brightness differences between Full Moons are relatively small and an actual comparison with other Full Moons is difficult to make by eye alone. Two exposures are blended in this supermoon and sky view from June 14. That Full Moon was also known to northern hemisphere…

2022年5月18日 A Jewel on the Flower Moon Image Credit & Copyright: Tomas Slovinsky Explanation: Cloudy skies plagued some sky watchers on Sunday as May’s Full Flower Moon slipped through Earth’s shadow in a total lunar eclipse. In skies above Chile’s Atacama desert this telephoto snapshot still captured an awesome spectacle though. Seen through thin high cirrus clouds just before totality began, a last sliver of sunlit crescent glistens like a hazy jewel atop the mostly shadowed lunar disk. This full moon was near perigee, the closest point in its elliptical orbit. It passed near the center of Earth’s dark umbral shadow during the 90 minute long total eclipse phase. Faintly suffused with sunlight scattered by the atmosphere, the umbral shadow itself gave the eclipsed moon…

2022年1月1日 The Full Moon of 2021 Image Credit & Copyright: Soumyadeep Mukherjee Explanation: Every Full Moon of 2021 shines in this year-spanning astrophoto project, a composite portrait of the familiar lunar nearside at each brightest lunar phase. Arranged by moonth, the year progresses in stripes beginning at the top. Taken with the same camera and lens the stripes are from Full Moon images all combined at the same pixel scale. The stripes still looked mismatched, but they show that the Full Moon’s angular size changes throughout the year depending on its distance from Kolkata, India, planet Earth. The calendar month, a full moon name, distance in kilometers, and angular size is indicated for each stripe. Angular size is given in minutes of arc corresponding to…

2021年04月30日 Pink and the Perigee Moon Image Credit & Copyright: Alice Ross Explanation: On April 25 a nearly full moon rose just before sunset. Welcomed in a clear blue sky and framed by cherry blossoms, its familiar face was captured in this snapshot from Leith, Edinburgh, Scotland. Known to some as a Pink Moon, April’s full lunar phase occurred with the moon near perigee. That’s the closest point in its not-quite-circular orbit around planet Earth, making this Pink Moon one of the closest and brightest full moons of the year. If you missed it, don’t worry. Your next chance to see a full perigee moon will be on May 26. Known to some as a Flower Moon, May’s full moon will actually be closer to…
