The World At Night (TWAN) 📷: Perseids on August 2019 Photos by @JeffDaiPhoto The Perseid meteor shower is peaking as Earth moves through the debris trail of parent Comet Swift Tuttle. In the early morning of August 13th, as the 13th moon set in west, the meteor shower become more active. Here are meteors taken at Xinjiang in recent nights. First photo is a composite image of 7 meteors in 2 hours before sunrise, taken at Nalati Grassland in Xinjiang, China. Many lovely cow seems enjoy the meteor shower a lot. Big dipper is visible just above the horizon. . © twanight.org/Dai #Jeff_Dai #twanight

The World At Night (TWAN) 📷: Perseid Meteor Shower From @BabakTafreshi: Streaking across the sky on the peak of Perseid Meteor Shower on the night of August 12-13, one of the most beautiful annually repeating sky events. Swipe to see a timelapse video of this scene from last year in Sierras, California. A sound effect is added to the moments of meteors to better spot them. Those at the end, in morning twilight, are mainly satellites, appearing longer in the video. This year on Monday night the nearly full moon hides away some of the meteors during the peak but still the brighter fireballs will turn on your sleepy eyes! The moon sets near 4 am and depending on your position there is about an hour of dark sky before dawn on Tuesday morning when you may see a meteor per minute, if you are far from light pollution. Perseids don’t appear mainly near the shower radiant in constellation Perseus, they can be anywhere in the sky, and more after midnight (Tuesday morning). The shower is active, at lower rate, within several nights of the peak specially Monday morning with an hour longer dark sky between moonset and dawn. ⁣ ⁣Background soundtrack by @AliRainiMusic. ⁣ . © twanight.org/Tafreshi #Babak_Tafreshi #twanight

The World At Night (TWAN) 📷: Milky Way and Equinox Aurora Photo by #TWAN_Guest: @ChiragUpreti From the photographer: "Chasing auroras in Iceland, we were lucky to witness a unique aurora under fortunate circumstances that made this shot possible. Auroras are breathtaking and pretty (exponentially more so when viewed for the first time), however they are also a source of natural light pollution. Here, the aurora appeared to slowly spread from the north, to west then south. The sky over the city of Vik was predicted to be cloudy for the night, but there was a lucky break in the cloud cover that reveled the near vertical Milky Way in this dark site. The illumination of the aurora as it approached the Milky Way was in stark contrast to the dark sky. The slowly dancing wall of magenta and yellow hues was followed by a bright green diffused glow as it advanced towards the Milky Way. Interestingly, the clouds near the horizon also took on a prominent green hue. Also seen in the distant horizon, likely is a precipitation shaft of a far away storm. The foreground here is farmland that leads to the open ocean. About 10-15 minutes after this shot the green glow enveloped the sky and the Milky Way details were lost, soon after the clouds came in and we called it a night. This was a very pleasant and welcome surprise for the Autumn equinox!" Technical details: A single-exposure image with Sony A7S2.

The World At Night (TWAN) 📷: Moonlit Star-Trails on May 2019 Photo by #TWAN_Guest: Bhaskar Sarkar @onewildwanderer From the photographer: This photo is taken from the rooftop of the Indian Antarctic Research Station, Bharati. In the foreground is one of the satellite antennas looking over the frozen Quilty Bay. It was a clear moonlit sky, the first one in 3 months since the winter had begun. With the sudden loss of cloud cover, the temperature had suddenly plummeted to below -30 degrees Celsius and the winds were peaking at around 30 knots. But this unanticipated appearance of clear sky was too much a temptation to hold me back from freezing my fingers off. The moon illuminated the foreground so vividly, while the Aurora Australis danced into the frame just at the right time. 📎Technical Details: 401 photos taken over 20 minutes stacked, Camera: Canon Eos 6D Mark II, Lens: Samyang 14mm/f2.8, Each photo has the following exif data - Exposure 1.6 seconds, ISO 6400, 14mm, f/2.8 , Photos stacked in Adobe Photoshop CS6 and edited in Adobe Lightroom 6 . 🌐 twanight.org/Guest #twanight

The World At Night (TWAN) @nightskyphotographer's photo is featuring today as APOD in NASA. 📷: The Veins of Heaven Explanation: Transfusing sunlight through a still dark sky, this exceptional display of noctilucent clouds was captured earlier this month, reflected in the calm waters of Vallentuna Lake near Stockholm, Sweden. From the edge of space, about 80 kilometers above Earth's surface, the icy cloudsthemselves still reflect sunlight even though the Sun is below the horizon as seen from the ground. Usually spotted at high latitudes in summer months the night shining clouds have made a strong showing so far during the short northern summer nights. Also known as polar mesopheric clouds they are understood to form as water vapor driven into the cold upper atmosphere condenses on the fine dust particles supplied by disintegrating meteors or volcanic ash. NASA's AIM mission provides daily projections of noctilucent clouds as seen from space. . © twanight.org/Heden #P_M_Heden #twanight

The World at Night (TWAN) @chen.p.kun is TWAN photographer of this month, July 2019. Known as the Peter Pan of the Stars, he has travelled to astronomical places around the globe and photographed the night sky from many dark sites. 🌐 twanight.org/Chen P.K. is the given-name initials of Chen Pei-Kung, who has probably traveled to more astronomical observatories and dark-sky sites than anyone else. He meets professional astronomers and amateur-astronomy fans around the world as he pursues his passion-photographing celestial sights. Since 1983 P.K. has regularly escaped to Lan-Yu, a small island near Taiwan that has a sky free from light and air pollution. And he frequently carries his camera and other instruments to Mount Jade, the highest point in Taiwan. But during the past two decades he has become a well-known world traveler, trekking from Mongolia to the Australian Outback and Mauna Kea in Hawaii in search of unique astrophotography opportunities-and dark skies. P.K. believes that "there is always something new that I can do." In Taiwan he has published more than a dozen books including an autobiography ("Peter Pan Under the Starlight") and two constellation albums. As a photojournalist, his articles and images have appeared in such publications as the New York Times and Sky&Telescope in the United States and the Temmon Guide in Japan. He is currently a contributing photographer of Sky&Telescope and his 2007 book titled "A Constellation Album: Stars and Mythology of the Night Sky" has published by Sky&Telescope. He often serves as an astronomy instructor at summer camps in Taiwan, and among the children he is known as the "Peter Pan of the Stars".

The World at Night (TWAN) @YuriBeletsky's photo is featuring as APOD in NASA on July 4. 📷: In the Shadow of the Moon Explanation: On July 2 denizens of planet Earth could stand in the Moon's dark umbral shadow during South America's 2019 total solar eclipse. It first touched down in the Southern Pacific Ocean, east of New Zealand. Racing toward the east along a narrow track, the shadow of the Moon made landfall along the Chilean coast with the Sun low on the western horizon. Captured in the foreground here are long shadows still cast by direct sunlight though, in the final moments before totality began. While diffraction spikes are from the camera lens aperture, the almost totally eclipsed Sun briefly shone like a beautiful diamond ring in the clear, darkened sky. . © twanight.org/Beletsky #Yuri_Beletsky #twanight

The World at Night (TWAN) @BabakTafreshi's photos during California Nightscapes photo workshop (babaktafreshi.com/workshop) . 1st📷: A beautiful meteor, at moonrise above the otherworldly landscape of Mono Lake, California. On any dark night, a consistent observer may see a meteor every 10-15 minutes on average, specially towards morning. The rate is more at meteor showers. The sporadic meteors like this are formed by random wandering meteoroids, little rocks or ice that enter the earth’s atmosphere at very high speeds, up to 160,000 mph (260,000 km/h). ⁣ 2nd📷: This singe-exposure photograph of 20 seconds is from a couple of nights ago, far from light pollution in Mono Lake looking at a little island of tufa. These limestone towers are formed by the precipitation of carbonate minerals in water. Mono Lake has no outlet and trapped salt made the lake very alkaline and salty. But the lake has an unusually productive ecosystem including a strange bacteria that was deeply analyzed by astrobiologist studying possibility of life in other worlds and extreme conditions. ⁣ 3rd📷: On June 19, I was standing at the shore of a 10,000 ft (3050 m) high lake in the Sierra Nevada, California. A surreal view was emerging as the rising moon hit the rugged peaks.

The camera on the Fornax Lightrack tracker. Images manually stacked and aligned as the difference in star positions at the bottom of the frame due to atmospheric refraction (the field was low in the west) made it impossible for Photoshop to align the images accurately. * 3rd📷: The ISS (Space Station) flies past the Pleiades star cluster, with reddish Mars below, and the larger Hyades star cluster at left with the reddish star Aldebaran. This was March 30, 2019, looking west into the evening twilight sky. The ISS was rising out of the west and twilight glow, climbing up the frame here. The sky gradient is from twilight and the Zodiacal Light in the west. Canadian astronaut David St. Jacques was on board at this time in early 2019. This is a stack of 3 x 3 minute tracked exposures for the background to smooth noise, mean combined, plus the single 3-minute exposure with the ISS, layered in with Lighten blend mode, all at f/3.5 with the Sigma 50mm lens and Canon 6D MkII at ISO 200. High haze and clouds added the star glows. though I also added an Orton effect layer to boost the star glow effect. I used the app GoSatWatch to preview the path of the ISS and plan the framing and timing. * 4th📷: Mars below the Pleiades star cluster and north (right) of the Hyades cluster, all in Taurus, on the evening of March 30, 2019.

The World At Night (TWAN) @Amir.Ho.Abolfath's photo is featuring today as APOD in NASA. 📷: AE Aurigae and the Flaming Star Nebula Explanation: Is star AE Aurigae on fire? No. Even though AE Aurigae is named the flaming star, the surrounding nebula IC 405 is named the Flaming Star Nebula, and the region shape gives the appearance of fire, there is no fire. Fire, typically defined as the rapid molecular acquisition of oxygen, happens only when sufficient oxygen is present and is not important in such high-energy, low-oxygen environments such as stars. The material that appears as smoke is mostly interstellar hydrogen, but does contain smoke-like dark filaments of carbon-rich dust grains. The bright star AE Aurigae, visible just to the lower right of the image center, is so hot it glows blue, emitting light so energetic it knocks electrons away from surrounding gas. When a proton recaptures an electron, light is emitted, as seen in the surrounding emission nebula. Featured here, the Flaming Star nebula lies about 1,500 light years distant, spans about 5 light years, and is visible with a small telescope toward the constellation of the Charioteer (Auriga). . © twanight.org/Abolfath #Amir_H_Abolfath #twanight

The World At Night (TWAN) 📷: Worm Moon Photo & video by @Miguel_Claro The image features the beginning of spring in the Northern Hemisphere with a beautiful Super “Worm Moon” – as it is named according to folklore – rising behind the Tower/Palace of Evoramonte. Supermoons happen when a full moon approximately coincides with the moon’s perigee, or a point in its orbit at which it is closest to Earth. In Evoramonte was signed on 26th May of 1834, a Peace Treaty known as “Convention of Evoramonte” or “Concession of Evoramonte” which ended the only Portuguese civil war in almost 900 years of History. Due to this important historical heritage, Evoramonte is also the birthplace of the European Network of Places of Peace (www.placesofpeace.eu). At the highest point of the village of Evoramonte rises the Tower/Palace of Evoramonte commonly considered as the “ex-libris” of the village. The Tower/ Palace of Evoramonte was built by the Dukes of Bragança D. Teodósio and D. Jaime as a symbol of its power reflected in the tie of Manueline reminiscences that is the symbolic mark of the heraldry of the House of Bragança. The image is a result of two combined exposures to help reveal all the details in the Moon's disk as well as in the foreground. . © twanight.org/Claro #Miguel_Claro #twanight

The World At Night (TWAN) @Juan_Carlo_Casado's photo is featuring today as APOD in NASA. 📷: Star Trails and the Equinox Sunrise Explanation: Stars trail and the Sun rises in this night and day composite panorama made on March 19. The view looks toward the eastern horizon from La Nava de Santiago, Spain. To create it, a continuous series of digital frames was recorded for about two hours and combined to trace the concentric motion of the stars through the night sky. A reflection of the Earth's rotation, star trails curve around the north celestial pole toward upper left and the south celestial pole toward the lower right. Of course on that day the Sun was near the celestial equator, a diagonal straight line in the wide-angle projection. A dense dimming filter was used to capture the Sun's image every two minutes. Superimposed on the star trails it rose due east in the morning sky. In the scene, foreground landscape and alocal prehistoric monument were illuminated by full moonlight, though. The monument's corridor faces nearly to the east and the equinox sunrise. © twanight.org/Casado #Juan_Carlos_Casado #twanight

After discovering this small creek with running water, the photographer returned to the site to watch the Milky Way rise in the dark southern skies, calculating the moment when Milky Way and precious flowing water would meet. In the panoramic night skyscape, stars and nebulae immersed in the glow along the Milky Way itself also shared that moment with the Milky Way's satellite galaxies the Large and Small Magellanic clouds above the horizon at the right.

The World at Night 📷: Now and Forever Photo by #TWAN_Guest: @P_Giacobazzi (Pierluigi Giacobazzi) From the photographer: Torrechiara is one of the best preserved fortifications in the whole Emilia Romagna region – northern Italy. It was re-built between 1448 and 1460 by Pier Maria Rossi and born with military function as defensive castle, later became the residence of Bianca Pellegrini – lover of Pier Maria Rossi. Among several beautiful frescoed rooms, particular attention deserves the Camera d’Oro (golden room), whose name comes from the leaves of gold that once covered the panels on the walls. The room still has a rare cycle of frescoes attributed to Benedetto Bembo depicting scenes of celebration of chivalric love referred to Bianca and Pier Maria. It is still possible to recognize the crests of the two lovers, two hearts with the phrases “Digne et in aeternum” (worthy and ever) and “Nunc et Semper” (now and forever), demonstrating the eternity of their love. The picture was recorded on June 16th 2018 at the end of a colorful sunset. It shows the celestial conjunction between a crescent Moon – 12% illuminated by the Sun – and the bright planet Venus. The nautical twilight gave me the possibility to observe and record the Earthshine: a soft, faint glow on the dark side of the Moon caused by the reflection of sunlight from the Earth. 📎Single-exposure image, DSLR: Nikon D750 – focal length: 60mm f/2.8 (used at f/4.0) - exposure: 1,0 sec – ISO: 200 * 🌐 twanight.org/Guest #twanight

The World at Night @Juan_Carlos_Casado's photo is featuring today as #APOD in #NASA. 📷: Stars, Meteors, and a Comet in Taurus Explanation: This was an unusual night to look in the direction of the Bull. The constellation Taurus is always well known for hosting two bright star clusters -- the Pleaides, visible on the right, and the comparatively diffuse Hyades, visible on the left. This night last month, however, was atypically the peak of the Geminid meteor shower, and so several meteors were caught shooting through the constellation withparallel trails. More unusually still, Comet Wirtanen was drifting through the constellation, here appearing near the image bottom surrounded by a greenish coma. The comet was near its brightest as it sped past the Earth. The orange star on the upper left is Aldebaran, considered to be the eye of the Bull. Aldebaran is the brightest star in Taurus and the 15th brightest star in the sky. The featured image is a combination of nearly 800 exposures taken from the Spanish village Albanyà. * © twanight.org/Casado #Juan_Carlos_Casado #twanight

The World at Night @YuriBeletsky's photo is featuring today as #APOD in #NASA. 📷: A Laser Strike at the Galactic Center Explanation: Why are these people shooting a powerful laser into the center of our Galaxy? Fortunately, this is not meant to be the first step in a Galactic war. Rather, astronomers at the Very Large Telescope (VLT) site in Chile are trying to measure the distortions of Earth's ever changing atmosphere. Constant imaging of high-altitude atoms excited by the laser -- which appear like an artificial star -- allow astronomers to instantly measure atmospheric blurring. This information is fed back to a VLT telescope mirror which is then slightly deformedto minimize this blurring. In this case, a VLT was observing our Galaxy's center, and so Earth's atmospheric blurring in that direction was needed. As for inter-galaxy warfare, when viewed from our Galaxy's center, no casualties are expected. In fact, the light from thispowerful laser would combine with light fromour Sun to together appear only as bright as a faint and distant star. * © twanight.org/Beletsky #Yuri_Beletsky #twanight

The World at Night 📷: Conjunction of Moon & Venus on January 2, 2019. Photos by @AlexConu Swipe left to see all photos. I photographed it around my favorite museum in Oslo, The Astrup Fearnley Museum of Modern Art. Conjunctions are apparent gatherings of celestial objects (usually from the Solar System) in a certain part of the sky. * © twanight.org/Conu #Alex_Conu #twanight

Wishing you a Happy New Year 2019! 📷: "Full Cold Moon" from last 22 December Photo by @Miguel_Claro This relatively abstract view captured in a double exposure with focus stacking, shows the Full Moon of December, behind a layer of clouds and immersed between dozens of branches from a foreground tree. The colourful hue that surrounds the moon, is a lunar corona formed while bright moonlight is diffracted by water droplets in thin clouds, drifting in front of the lunar disk. The image was captured in the historic centre of Évora, a @UNESCO #World_Heritage site, located in Dark Sky® Alqueva reserve, Portugal. According to the Old Farmer’s Almanac, the December full moon is also called the “Full Cold Moon”. The last time a full moon coincided with the solstice was in 2010, and the next will be in 2094. Hope you like it. * © twanight.org/Claro #Miguel_Claro #twanight

The World at Night LAMOST & Geminids (Photo Composite) Photo by #TWAN_Guest: Luocheng From the photographer: During the peak of 2015 Geminid Meteor Shower most of China was cloudy. But after snow on the night of Dec 13th, Xinglong Station of NAOC (National Astronomical Observatory of China) has very clear atmospheric conditions. In the night of 14th, I saw the wonderful cosmic fireworks show in the temperature of -10°C. Here are 74 meteors captured in 6 hours from midnight to 6 o'clock on Dec 15th. They are composited to one picture by the alignment of stars. At 1:29 a.m. (Beijing time),15th Dec, a jewelry blue fireball dropped In the treetops and the wall of LAMOST was lit by a dazzling fireball. The Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST), also known as the Guo Shoujing Telescope after the 13th-century Chinese astronomer.

The World at Night A Quadruple Lunar Halo Over Spain Photo by #TWAN_Guest: Dani Caxete @danikxt From the photographer: "Sometimes falling ice crystals make the atmosphere into a giant lens causing arcs and halos to appear around the Sun or Moon. This past Saturday night was just such a time near Madrid, Spain, where a winter sky displayed not only a bright Moon but as many as four rare lunar halos. The brightest object, near the top of the above image, is the Moon. Light from the Moon refracts through tumbling hexagonal ice crystals into a 22 degree halo seen surrounding the Moon. Elongating the 22 degree arc horizontally is a circumscribed halo caused by column ice crystals. More rare, some moonlight refracts through more distant tumbling ice crystals to form a (third) rainbow-like arc 46 degrees from the Moon and appearing here just above a picturesque winter landscape. Furthermore, part of a whole 46 degree circular halo is also visible, so that an extremely rare -- especially for the Moon -- quadruple halo was actually imaged. The snow-capped trees in the foreground line the road Puerto de Navacerrada in the Sierra de Guadarrama mountain range near Madrid. Far in the background is a famous winter skyscape that includes Sirius, the belt of Orion, and Betelgeuse all visible between the inner and outer arcs. Halos and arcs typically last for minutes to hours, so if you do see one there should be time to invite family, friends or neighbors to share your unusual lensed vista of the sky." * 🌐 twanight.org/Guest #twanight
