2017年07月26日:纪念碑谷上空的银河-(The Milky Way over Monument Valley)

2001年09月07日:日与月-(Moon AND Sun)
2001年09月07日:日与月-(Moon AND Sun)--原图下载{mtitle title="日与月"/}Composite Image Credit: Fred Espenak (courtesy ofwww.MrEclipse.com)说明: 今天再呈现一张合成图,它是2001年6月21日全蚀时,在辛巴威Chisamba地区所拍摄的22张太阳与月亮影像所组合出来的。这些多重曝光的影像,在经过电脑数位化处理及合成后,将许多细节展露无遗,单一相机曝光或肉眼观测是无法看得如此清楚的。其中最引人注意的特点,是自太阳外层大气或称日冕伸出的流线。我们平常是不可能看到这种景像,只有在新月遮住明亮的日盘时,人类才有这个眼福。在地球反照光的照射之下,在这幅影像中,还可以看到月亮靠地球这面的一些月貌。除此之外,你看到高挂在月盘左上方的巨大日珥没?月球中下方,离月亮一个日盘宽度的暗淡恒星是双子座1。{lamp/}原文:{mtitle title="Moon AND Sun"/}Composite Image Credit: Fred Espenak (courtesy ofwww.MrEclipse.com)Explanation: Today's composite image was made from 22 separate picturesof the Moon and Sun all taken fromChisamba, Zambia during thetotal phase of the 2001 June 21 solar eclipse.The multiple exposureswere digitally processed and combined tosimultaneously show a wealth of detail which no single cameraexposure or naked-eye observation could easily reveal.Most striking are the incredible flowing streamersof the Sun's outer atmosphere orsolar corona, notoriously difficult to see except whenthenew Moon blocks the bright solar disk.Features on the darkened near sideof the Moon canalso be made out,illuminatedby sunlight reflected fromafull Earth.A giant solar prominence seems to hangjust beyond the Moon's eastern (left) edge while about onediameter farther east of the eclipsed Sun is therelatively faint (4th magnitude)star 1 Geminorum.
