2023年06月16日:波罗的海从日落到日出-(Sunset to Sunrise over the Baltic Sea)
[2023年06月16日:波罗的海从日落到日出-(Sunset to Sunrise over the Baltic Sea)--原图下载](https://apod.nasa.gov/apod/image/2306/baltic-sea-timelapse-image.jpg"onMouseOver="if (document.images)document.imagename1.src='https://apod.nasa.gov/apod/image/2306/baltic-sea-timelapse-image_with-timescale600.jpg';"onMouseOut="if (document.images)document.imagename1.src='image/2306/baltic-sea-timelapse-image600.jpg';){mtitle title="波罗的海从日落到日出"/}Image Credit &Copyright: Bernd Pröschold(TWAN)说明: 这片从瑞典海岸俯瞰波罗的海之静谧视野,以压缩时间的方式,在单张影像里呈现了一个夜晚时光的流逝。从日落到日出之间,月光照亮了美丽的海面和天空景观。转瞬即逝的云朵、固定的恒星及摇曳的北极光,都在地球的天空中留下了它们的蹤迹。为了建构这幅缩时影像,摄影者于6月的满月那晚,在当地时间晚间7:04到隔天早晨6:35之间记录了3296帧影片定格。然后依时间流逝的顺序,从相对应的影像定格撷取一行像素,从左到右依序组合出这幅宽度为3296像素的数位影像。{lamp/}原文:{mtitle title="Sunset to Sunrise over the Baltic Sea"/}Image Credit &Copyright: Bernd Pröschold(TWAN)Explanation: This serene view fromthe coast of Sweden looks across the Baltic seaand compresses time, presenting the passage of one night in asingle photograph.From sunset to sunrise,moonlightilluminates the creative sea and skyscape.Fleeting clouds, fixed stars, and flowingnorthern lightsleave their traces inplanet Earth's sky.To construct the timelapse image,3296 video frames were recorded on the nightof a nearly full moon between 7:04pm and 6:35am local time.As time progressesfrom left to right,a single column of pixels was takenfrom the correspondingindividual frame and combined in sequence into a single digital image3296 pixels wide.

2021年08月26日:蓝色时段的满月-(A Blue Hour Full Moon)
2021年08月26日:蓝色时段的满月-(A Blue Hour Full Moon)--原图下载{mtitle title="蓝色时段的满月"/}Image Credit &Copyright:Giorgia Hofer说明: 自然景观摄影者与其他地球景观的粉丝,通常都很期待蓝色时段。这段时间是指暮曙光时分里,在日出前或日落后的这段期间,该时太阳在地平面之下,但大地与天空全都沐浴在泛蓝的美丽辉光里。 这幅摄于8月21日落后的蓝色时段影像,记录近满相、与太阳反向的月轮,从义大利.科尔蒂纳丹佩佐镇附近的嵯峨阿尔卑斯山后方升起。这座沐浴在泛蓝晕光里的金字塔状安特拉奥峰,是此区最高耸的阿尔卑斯山峰,有多洛米蒂山脉之王的称号。虽然这轮明月在散发泛黄的月光,不过就连它也有这季的蓝月之称。从至点到分点之间的时日为一季,而在拥有4轮满月的季里,第三轮满月称为蓝月。在目前的季节里,第四轮满月将在今年秋分的前一天、9月20日的蓝色时段升起。{lamp/}原文:{mtitle title="A Blue Hour Full Moon"/}Image Credit &Copyright:Giorgia HoferExplanation: Nature photographers and other fans of planet Earthalways look forward tothe bluehour.That's the transitionin twilight,just before sunrise or after sunset, whenthe Sun is below the horizon but land and sky are still suffused witha beautiful blue light.After sunset on August 21,this blue hour snapshot captured the nearly full Moon as itrose opposite the Sun, above the rugged Italian Alps fromCortina d'Ampezzo, Italy.Sharing bluish hues with the sky, the rocky pyramid of Monte Antelao,also known as the King of the Dolomites,is the region's prominent alpine peak.The moonlightis yellow, but even so this full Moon was known to someas a seasonal Blue Moon.That's because by one definitionthe third full Moon of a season with four full moonsin it is called a Blue Moon.Recognizing a season as the time between a solstice and an equinox,this season's fourthfull Moon will be risingin the blue hour of September 20, just before September's equinox.

2021年07月16日:月光里的金星与火星-(Love and War by Moonlight)
2021年07月16日:月光里的金星与火星-(Love and War by Moonlight)--原图下载{mtitle title="月光里的金星与火星"/}Image Credit &Copyright: Shi Huan说明: 在这幅7月11日摄于地球.刚果共合国.卢阿拉巴省的静谧影像里,以西洋神话爱神(Venus)为名的金星和以战神(Mars)为名的火星,一同沐浴在月光中。这幅影像除了拍下刚日落后的暮光西方天空,也记录了受地照光照亮、原本非常黝黑的新月夜面。目前月亮已移至他处,但在地球天空第三亮、亮度排在太阳与月亮之后的金星,仍以昏星之姿在西方天空绽放光芒。影像中位在明亮金星上方的火星,后来愈来愈接近金星,在7月13日接近到与月亮相距约1个满月的宽度。在目前的暮光天空中,火星逐渐远离非常明亮的金星,不过二者都往亮星轩辕十四靠近。于这片视野的顶缘之外的狮子座最亮星轩辕十四,在接下来数日的暮光天空中,将接续有金星及火星来访。{lamp/}原文:{mtitle title="Love and War by Moonlight"/}Image Credit &Copyright: Shi HuanExplanation: Venus,named for the Roman goddess of love, andMars,the war god's namesake, come togetherby moonlightin this serene skyview, recorded on July 11from Lualaba province, Democratic Republic of Congo, planet Earth.Taken in the western twilight sky shortly after sunsetthe exposure also recordsearthshine illuminating the otherwisedark surface of theyoung crescent Moon.Of course the Moon has moved on.Venus still shines in the west though as theeveningstar, third brightest object in Earth's sky,after the Sun and the Moon itself.Seen here above a brilliant Venus,Mars moved even closerto the brighter planet and by July 13 could be seen onlyabout a Moon's width away.Mars has since slowly wandered away from much brighter Venus in thetwilight, but both are sliding toward bright star Regulus.Alpha star of the constellation Leo, Regulus lies off thetop of this frame and anticipates avisit from Venusand then Mars in twilight skies ofthe coming days.

2018年10月08日:玫瑰星云与锥状星云之间的彗星21P-(Comet 21P Between Rosette and Cone Nebulas)
2018年10月08日:玫瑰星云与锥状星云之间的彗星21P-(Comet 21P Between Rosette and Cone Nebulas)--原图下载{mtitle title="玫瑰星云与锥状星云之间的彗星21P"/}Image Credit & Copyright: Fritz Helmut Hemmerich说明: 这个绿灰色彗星的小碎片,预期会在今晚穿过地球的大气。更明确的说,来自贾科比尼-津纳彗星(Comet 21P / Giacobini-Zinner)彗核的碎片,所形成的天龙座流星雨会在今晚达到极大期。今年的天龙座流星应轻易可辨,因为流星出现率可能在日落后不久达到峰值的这群流星雨,基本上不会受到月光的干扰。不过,耐心是关键,虽然彗星21P刚在上个通过地球附近,但是天龙座流星雨通常每小时数颗的出现率,并不预期会增加。话虽如此,流星出现率极难预测,何况天龙座流星在1933年、1946年和2011年都有很精采的演出。在2星期前拍摄的这张主题影像里,彗星21P正好位在玫瑰星云(左铲)与锥状星云(右下)之间,之后它就从当时在木星轨道附近的位置向外退去,大约在6年半之后才会再次回归。{lamp/}原文:{mtitle title="Comet 21P Between Rosette and Cone Nebulas"/}Image Credit & Copyright: Fritz Helmut HemmerichExplanation: Small bits of this greenish-gray comet are expected to streak across Earth's atmosphere tonight.Specifically, debris from the eroding nucleus of Comet 21P / Giacobini-Zinner, pictured, causes the annual Draconids meteor shower, which peaks this evening. Draconid meteors are easy to enjoy this year because meteor rates will likely peak soon after sunset with the Moon's glare nearly absent. Patience may be needed, though, as last month's passing of 21P near the Earth's orbit is not expected to increase the Draconids' normal meteor rate this year of (only) a few meteors per hour. Then again, meteor rates are notoriously hard to predict, and the Draconids were quite impressive in 1933, 1946, and 2011. Featured, Comet 21P gracefully posed between the Rosette (upper left) and Cone (lower right) nebulas two weeks ago before heading back out to near the orbit of Jupiter, to return again in about six and a half years.

2018年09月14日:黄刀镇上空的冰晕 -(Ice Halos at Yellowknife)
[2018年09月14日:黄刀镇上空的冰晕 -(Ice Halos at Yellowknife)--原图下载](https://apod.nasa.gov/apod/image/1809/image1bedingfield.jpg"onMouseOver="if (document.images)document.imagename1.src='https://apod.nasa.gov/apod/image/1809/image2bedingfield1024.jpg';"onMouseOut="if (document.images)document.imagename1.src='image/1809/image1bedingfield1024.jpg';){mtitle title="黄刀镇上空的冰晕 "/}Image Credit &Copyright: Stephen Bedingfield说明: 你以前可能见过出现在太阳周围的晕环。在各种冰晕之中,比彩虹还要常见的22度晕很容易分辨,尤其是眼睛未受阳光直射的话。不过,要像上面这张摄于地面的照片,同时有多种不同的冰晕出现,仍属非常罕见,其中可辨的包括幻日(sundog)、正切晕弧(tangent)、外晕弧(infralateral)和彩晕弧(Parry arc)。上面这张影像,是在9月4日近午之时,摄于加拿大.西北地区的黄刀镇。这些美丽的光弧,是阳光(或月光)在穿过地球大气中的六边形冰晶时,受到反射及折射所产生的。想当然耳,其他系外行星的天空冰晕,形态可能也会不同。{lamp/}原文:{mtitle title="Ice Halos at Yellowknife"/}Image Credit &Copyright: Stephen BedingfieldExplanation: You've probably seen a circlearound the Sun before.More common than rainbows, ice halos,like a 22 degree circular halo for example, can be easy to spot,especially if you can shade your eyes from direct sunlight.Still it's rare to see such a diverserange of ice halos,includingsundogs, tangent, infralateral, and Parry arcs,all found in thissnapshot from planet Earth.The picture was quickly taken in the late morning ofSeptember 4 from Yellowknife, Northwest Territories, Canada.The beautiful patterns are generated as sunlight(or moonlight)is reflected and refracted in six-sided water ice crystalsin Earth's atmosphere.Of course, atmospheric ice halos in the skies ofother worldsare likelyto be different.

2016年10月29日:惠特比修道院的月落-(Moonset at Whitby Abbey)
2016年10月29日:惠特比修道院的月落-(Moonset at Whitby Abbey)--原图下载{mtitle title="惠特比修道院的月落"/}Image Credit &Copyright:Chris Kotsiopoulos(GreekSky)说明: 在这幅怪异的夜景里,十月的猎人之月,在地平面附近绽放光华并向惠特比修道院的拱门后方隐没。而座落在英格兰.约克郡海岸悬崖上,部分受到月光照耀的荒废本笃会修道院之院区和立墙则俯视着北海。布拉姆·斯托克1897年《德古拉》小说的粉丝,当会知道这座修道院和惠特比城;因为这位最着名的吸血鬼─川西瓦尼亚伯爵在发生海难登陆在英格兰海岸之后,随即幻成一只巨狗,跳上岸并奔往这座位在悬崖上的废弃修道院。这幅360度全景的精采鱼眼风格影像,是由23张照片数位拼接而成。{lamp/}原文:{mtitle title="Moonset at Whitby Abbey"/}Image Credit &Copyright:Chris Kotsiopoulos(GreekSky)Explanation: October's Hunters Moon shines near the horizon,setting beyond the arches of Whitby Abbey in this eerie night scene.The moonlightpartly illuminates the ruined Benedictine abbey'sgrounds and walls on a cliff overlooking the North Seafrom England's Yorkshire coast.Fans of Bram Stoker's 1897novel Draculawill recognize the abbey and town of Whitby as thelocation of the Transylvanian count's shipwrecked landing on English shores.There fiction's most famous vampire transformed into an immense dog,jumped ashore and ran up the cliff to the ruined abbey.A 360 degree panorama,thedramatic fisheye view was created from 23 digitally stitched photos.
