白昼的月亮遇见晨星
2023年11月16日 Daytime Moon Meets Morning Star Image Credit & Copyright: Katarzyna Kaczmarczyk Explanation: Venus now appears as Earth’s brilliant morning star, shining above the southeastern horizon before dawn. For early morning risers, the silvery celestial beacon rose predawn in a close pairing with a waning crescent Moon on Thursday, November 9. But from some northern locations, the Moon was seen to occult or pass in front of Venus. From much of Europe, the lunar occultation could be viewed in daylight skies. This time series composite follows the daytime approach of Moon and morning star in blue skies from Warsaw, Poland. The progression of eight sharp telescopic snapshots, made between 10:56am and 10:58am local time, runs from left to right, when Venus winked out behind the…

2023年2月25日 Crescent Moon Occultation Image Credit & Copyright: Fefo Bouvier Explanation: On February 22, a young Moon shared the western sky at sunset with bright planets Venus and Jupiter along the ecliptic plane. The beautiful celestial conjunction was visible around planet Earth. But from some locations Jupiter hid for a while, occulted by the crescent lunar disk. The Solar System’s ruling gas giant was captured here just before it disappeared behind the the Moon’s dark edge, seen over the Río de la Plata at Colonia del Sacramento, Uruguay. In the serene river and skyscape Venus is not so shy, shining brightly closer to the horizon through the fading twilight. Next week Venus and Jupiter will appear even closer in your evening sky. Tomorrow’s picture: Saturn’s…
月亮临边上方的火星
2022年12月9日 Mars Rises above the Lunar Limb Image Credit & Copyright: Tom Glenn Explanation: On the night of December 7 Mars wandered near the Full Moon. In fact the Red Planet was occulted, passing behind the Moon, when viewed from locations across Europe and North America. About an hour after disappearing behind the lunar disk Mars reappears in this stack of sharp video frames captured from San Diego, planet Earth. With the Moon in the foreground Mars was a mere 82 million kilometers distant, near its own opposition. Full Moon and full Mars were bright enough provide the spectacular image with no exposure adjustments necessary. In the image Mars appears to rise just over ancient, dark-floored, lunar crater Abel very close to the southeastern edge…
血月与冰质巨行星
2022年11月11日 Blood Moon, Ice Giant Image Credit & Copyright: Ryan Han Explanation: On November 8 the Full Moon turned blood red as it slid through Earth’s shadow in a beautiful total lunar eclipse. During totality it also passed in front of, or occulted, outer planet Uranus for eclipse viewers located in parts of northern America and Asia. For a close-up and wider view these two images were taken just before the occultation began, captured with different telescopes and cameras from the same roof top in Shanghai, China. Normally very faint compared to a Full Moon, the tiny, pale, greenish disk of the distant ice giant is just to the left of the Moon’s edge and about to disappear behind the darkened, red lunar limb. Though…

2022年6月2日 Lunar Occultation of Venus Image Credit & Copyright: Quentin Gineys Explanation: On May 27 Venus rose as the morning star, near the waning crescent Moon in a predawn sky already full of planets. It was close on the sky to the Moon’s crescent and a conjunction of the second an third brightest celestial beacons were enjoyed by skygazers around the world. But seen from locations along a track through southeast Asia and the Indian Ocean the Moon actually passed in front of Venus in a lunar occultation. In this animated gif the 75 percent illuminated disk of Venus approaches and just begins to disappear behind the sunlit southwestern lunar limb. The telescopic frames used to construct it were captured from Reunion Island in the…

2021年8月21日 Triple Transit and Mutual Events Image Credit & Copyright: Christopher Go Explanation: These three panels feature the Solar System’s ruling gas giant Jupiter on August 15 as seen from Cebu City, Philippines, planet Earth. On that date the well-timed telescopic views detail some remarkable performances, transits and mutual events, by Jupiter’s Galilean moons. In the top panel, Io is just disappearing into Jupiter’s shadow at the far right, but the three other large Jovian moons appear against the planet’s banded disk. Brighter Europa and darker Ganymede are at the far left, also casting their two shadows on the gas giant’s cloud tops. Callisto is below and right near the planet’s edge, the three moons in a triple transit across the face of Jupiter. Moving…
月亮临边旁的火星
2020年8月15日 Mars at the Moon’s Edge Image Credit & Copyright: Sergio Scauso Explanation: Does the Moon ever block out Mars? Yes, the Moon occasionally moves in front of all of the Solar System’s planets. Just this past Sunday, as visible from some locations in South America, a waning gibbous Moon eclipsed Mars. The featured image from Córdoba, Argentina captured this occultation well, showing a familiar cratered Moon in the foreground with the bright planet Mars unusually adjacent. Within a few seconds, Mars then disappeared behind the Moon, only to reappear a few minutes later across the Moon. Today the Moon moves close to, but not in front of, Venus. Because alignments will not have changed by much, the next two times the Moon passes through…
