2022年11月12日 Eclipse in the City Image Credit & Copyright: Stan Honda Explanation: A darker Moon sets over Manhattan in this night skyscape. The 16 frame composite was assembled from consecutive exposures recorded during the November 8 total lunar eclipse. In the timelapse sequence stars leave short trails above the urban skyline, while the Moon remains immersed in Earth’s shadow. But the International Space Station was just emerging from the shadow into the sunlit portion of its low Earth orbit. As seen from New York City, the visible streak of this ISS flyover starts near a star in Taurus and tracks right to left, through the belt of Orion and over Sirius, alpha star of Canis Major. Gaps along the bright trail of the fast moving…

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11月10日 Total Lunar Eclipse Image Credit: KPNO / NOIRLab / NSF / AURA / Petr Horalek (Institute of Physics in Opava) Explanation: The beginning, middle, and end of a journey through planet Earth’s colorful umbral shadow is captured in this timelapse composite image of a total lunar eclipse. Taken on November 8 from Kitt Peak National Observatory this eclipse’s 1 hour and 25 minute long total phase starts on the right and finishes on the left. Reddened sunlight, scattered into the central shadow by Earth’s dusty atmosphere produces the dramatic dark red hues reflected by the lunar disk. For this eclipse, additional reddening is likely due to scattering from ash lingering in the atmosphere after a large volcanic eruption in the southern Pacific earlier this…

2022年11月5日 Lunar Eclipse at the South Pole Image Credit & Copyright: Aman Chokshi Explanation: Last May 16 the Moon slid through Earth’s shadow, completely immersed in the planet’s dark umbra for about 1 hour and 25 minutes during a total lunar eclipse. In this composited timelapse view, the partial and total phases of the eclipse were captured as the Moon tracked above the horizon from Amundsen-Scott South Pole Station. There it shared a cold and starry south polar night with a surging display of the aurora australis and central Milky Way. In the foreground are the BICEP (right) and South Pole telescopes at the southernmost station’s Dark Sector Laboratory. But while polar skies can be spectacular, you won’t want to go to the South Pole…

2022年5月20日 A View from Earth’s Shadow Image Credit & Copyright: Maxime Oudoux Explanation: This serene sand and skyscape finds the Dune of Pilat on the coast of France still in Earth’s shadow during the early morning hours of May 16. Extending into space, the planet’s dark umbral shadow covered the Moon on that date. From that location the total phase of a lunar eclipse had begun before moonset. Still in sunlight though, the International Space Station crossed from the western horizon and Earth’s largest artificial moon traced the bright flat arc through the sky over 400 km above. Simply constructed, the well-planned panoramic scene was captured over a 5 minutes in a series of consecutive images. Tomorrow’s picture: Abell 7 地球影子里的景观 影像提供与版权: Maxime Oudoux 说明:…

2022年5月19日 A Digital Lunar Eclipse Image Credit & Copyright: Michael Cain Explanation: Recorded on May 15/16 this sequence of exposures follows the Full Moon during a total lunar eclipse as it arcs above treetops in the clearing skies of central Florida. A frame taken every 5 minutes by a digital camera shows the progression of the eclipse over three hours. The bright lunar disk grows dark and red as it glides through planet Earth’s shadow. In fact, counting the central frames in the sequence measures the roughly 90 minute duration of the total phase of this eclipse. Around 270 BC, the Greek astronomer Aristarchus also measured the duration of total lunar eclipses, but probably without the benefit of digital watches and cameras. Still, using geometry…

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…

2021年06月04日 Blood Monster Moon Image Credit & Copyright: Chirag Upreti Explanation: On May 26, the Full Flower Moon was caught in this single exposure as it emerged from Earth’s shadow and morning twilight began to wash over the western sky. Posing close to the horizon near the end of totality, an eclipsed lunar disk is framed against bare oak trees at Pinnacles National Park in central California. The Earth’s shadow isn’t completely dark though. Faintly suffused with sunlight scattered by the atmosphere, the inner shadow gives the totally eclipsed moon a reddened appearance and the very dramatic popular moniker of a Blood Moon. Still, the monstrous visage of a gnarled tree in silhouette made this view of a total lunar eclipse even scarier. Tomorrow’s picture:…

2021年05月28日 Total Lunar Eclipse from Sydney Image Credit & Copyright: Peter Ward (Barden Ridge Observatory) Explanation: The reddened shadow of planet Earth plays across the lunar disk in this telescopic image taken on May 26 near Sydney, New South Wales, Australia. On that crisp, clear autumn night a Perigee Full Moon slid through the northern edge of the shadow’s dark central umbra. Short for a lunar eclipse, its total phase lasted only about 14 minutes. The Earth’s shadow was not completely dark though. Instead it was suffused with a faint red light from all the planet’s sunsets and sunrises seen from the perspective of an eclipsed Moon, the reddened sunlight scattered by Earth’s atmosphere. The HDR composite of 6 exposures also shows the wide range…
