    Explanation:
    How do animals react to a total solar eclipse? The featured image shows a stork roosting on her nest in Poland at a partial phase of the recent total solar eclipse. If you are lucky enough to experience a total eclipse somewhere quiet and close to nature, you may be able to notice unusual daytime animal behaviors. During totality, you may hear nighttime sounds like crickets and frogs and see fireflies. In the dark, most birds are quiet. Thinking that it is time to go to bed, ducks and other waterfowl prepare to sleep on one leg, with their heads turned around and their beaks tucked into their back feathers (they don't really sleep with their heads tucked under one wing). When sunlight returns at the end of totality, songbirds greet the new "morning" with their dawn songs. The crickets and frogs go quiet again. Animals and people resume their lifes, only briefly disturbed by the chance alignment of our Sun and Moon.

    Explanation:
    Pretend you have never heard of a solar eclipse. The Sun’s behavior has been predictable your whole life. One day, you witness the sky transform as it does in today’s spliced image spanning two hours of the August 12, 2026 solar eclipse. The Sun disappears, leaving behind a bright, empty ring. What would you think had happened? Humans have interpreted eclipses in countless ways throughout history, embedding beliefs about connection, rebirth, or danger into culture. “Eclipse” comes from the Greek word “ékleipsis” meaning “abandonment”. In ancient Greece, the solar eclipse marked the anger of the gods and the Sun abandoning humanity. To the Diné people, this celestial alignment is a time of renewal. Out of respect and to avoid the danger of sunlight, the Diné stay inside until the Sun and Moon separate. The Batammariba people of Benin and Togo believe that the Sun and Moon fight during an eclipse, so the community encourages peace among themselves. Eclipses are an example of the longstanding connection between astronomy and society.

    Launch of the Roman Space Telescope
    * Video Credit: NASA
    nasa.gov/

    Explanation:
    A new telescope has been launched into space to study the universe. The Nancy Grace Roman Space Telescope (RST) has the same size main mirror as the Hubble Space Telescope (HST) but sees 100 times more sky during each snapshot. This is possible because when compared to HST, RST's main mirror is more curved, its secondary mirror is closer, and its main camera is larger. The result is that RST can inspect more of the sky more quickly, likely allowing, among other capabilities, the discovery of many more supernovas which tell us more about the expansion rate and composition of our universe, and many more planets orbiting other stars that tell us more about the possibilities for life elsewhere in the universe. RST will orbit the Sun, not the Earth, like the James Webb Space Telescope. The featured video shows Roman being launched yesterday from Kennedy Space Center, Florida, USA aboard a SpaceX Falcon Heavy rocket.

    A Plane Lunar Eclipse
    * Image Credit: Paulo Ferreira
    instagram.com/paulofwild/

    Explanation:
    Did you need to be on the right side of this airplane to see this eclipse? No. Lunar eclipses are routinely seen from the half of the Earth facing the Moon when the eclipse occurs, making them some of the most commonly witnessed astronomical events. You don't even need any special equipment to see one -- just your unaided eyes. Lunar eclipses are also some of the most photographed astronomical events because, unlike with a solar eclipse, your eyes and camera do not have to look toward the bright Sun. However, considering the featured image taken last week from Portugal, if you were on the left side of that airplane during takeoff, you might have trouble seeing it -- at first. But even then, after takeoff, since lunar eclipses typically last for hours, you might soon be able to safely cross the aisle(s) to see it.

    Plane Contrail and Sun Halo
    * Image Credit & Copyright: Alexandros Maragos
    alexandrosmaragos.com/about/

    Explanation:
    What's happened to the sky? Several common features of the daytime sky are interacting in uncommon ways. First, well behind the silhouetted hills, is the typically bright Sun. In front of the Sun are thin clouds, possibly the home to a layer of hexagonal ice crystals that together are creating the 22 degree halo of light surrounding the Sun. The unusual bent line that crosses the image is a contrail -- a type of cloud created by a passing airplane. Much of the contrail must actually be further away than the thin cloud because it casts a shadow onto the cloud, giving an unusual three-dimensional quality to the featured image. The featured image was taken in late January in the city of Patras in West Greece.

    Contemplating the Sun
    * Image Credit & Copyright: Steven Gilbert
    flickr.com/photos/stevethatsmy

    Explanation:
    Have you contemplated your home star recently? Featured here, a Sun partially eclipsed on the top left by the Moon is also seen eclipsed by earthlings contemplating the eclipse below. This spectacular menagerie of silhouettes was taken in 2012 from the Glen Canyon National Recreation Area near Page, Arizona, USA, where park rangers and astronomers expounded on the unusual event to interested gatherers. Also, faintly visible on the Sun's disk, just to the lower right of the dark Moon's disk, is a group of sunspots. A new solar eclipse will occur this week and give many people in northern North America, Europe, and northwestern Africa a new chance to contemplate a partially eclipsed Sun. A thin swath of Earth from Greenland to Portugal will further experience a total solar eclipse. An open question is whether any meteors from the peaking Perseids will be visible during totality.

    Starry Night II
    * Image Credit & Copyright: Rodrigo Guerra
    instagram.com/rodrigoguerra13/
    * Original Painting: Vincent van Gogh
    en.wikipedia.org/wiki/Vincent_

    Explanation:
    Does this scene look familiar? It is a modern recreation of the famous painting Starry Night by Vincent van Gogh. Both the image and the painting depict a tall tree on the left, a crescent moon on the upper right, the planet Venus just to the right of the tree, a foreground horizon rising from left to right, and clouds above the horizon. Differences include that the photograph was taken in mid-April earlier this year in Cascavel, Brazil, while the painting was composed in Saint-Rémy-de-Provence, France, in 1889. The original Starry Night is considered by many to be one of the three most famous paintings in the world today and a statement about the wonders of the night sky. Today is (roughly) the anniversary of the morning that van Gogh saw the sky that he later painted in his version of Starry Night.

    Triple Shockwave from Sun Crossing Rocket
    * Image Credit & Copyright: John Winkopp (WAI Media)

    Explanation:
    What's happening to this Sun-crossing rocket? The SpaceX Falcon 9 rocket, visible on the upper left, launched only about one minute before this amazing image was captured. As it rose to low Earth orbit from Cape Canaveral, Florida, USA, in late May, the rocket became supersonic before it crossed the disk of the distant Sun -- from the perspective of the well-placed photographer. The spacecraft's high speed caused bow-shaped compressed-air shockwaves to form across leading surfaces, with at least three visible even outside the Sun's disk because they refract sunlight. The trailing exhaust caused turbulence visible on the lower right. None of this was damaging to the robotic Starlink 10-53 mission, which delivered 29 communications satellites to low Earth orbit as planned. And if that isn't amazing enough - the Sun had spots!

    10 Days of Venus and Jupiter
    * Image Credit & Copyright: Aditya Pawar
    instagram.com/astro_aditya49/

    Explanation:
    Venus and Jupiter may have caught your attention lately. The recent close conjunction of the two brightest planets in recent evening skies has been hard to miss. With Jupiter at the top, starting on May 30 and ending on June 8, their close approach was chronicled daily, left to right, in the featured panels from Maharashtra, India. Near the western horizon, the evening sky colors and exposures used for each panel depend on the local conditions near sunset. At their closest on June 9, the celestial pair appeared to be only about three times the width of a full moon apart. Of course, on that date, the two planets were physically separated by over 600 million kilometers in their orbits around the Sun. In the coming days, Jupiter will slowly settle into the sunset glare, but Venus will continue to move farther from the Sun in the western sky to excel in its current role as the brilliant evening star.

    Venus and Jupiter: Conjunction from Avebury

    * Image Credit & Copyright: Josh Dury
    joshduryphoto-media.com/

    Explanation:
    To see Venus and Jupiter together this month, you won't need binoculars or even a telescope. Just look up after sunset and you'll find them emerging as the sky grows dark near the western horizon. In fact, on June 9 the two brightest planets were in close conjunction, separated on the sky by less than 2 degrees from our perspective. Since (brighter) inner planet Venus orbits the Sun faster than outer planet Jupiter, it catches up with and passes the outer planet along the ecliptic roughly every 13 months. But every three years or so their resulting conjunction can be viewed far enough from the Sun to be easily seen in Earth's twilight skies. On June 9, the two celestial beacon's close "cosmic kiss" was captured here next to two large standing stones, the remains of a cove near the center of a 4,000 year old stone circle at Avebury, UK. Larger than Stonehenge, the Avebury henge and stone circle complex is also recognized as one of the most significant neolithic ceremonial sites on planet Earth.

    Jupiter and Venus from Earth

    scienceinpoland.pap.pl/en/news

    Explanation:
    It was visible around the world. The sunset conjunction of Jupiter (left) and Venus (right) in 2012 was visible almost no matter where you lived on Earth. Anyone on our planet with a clear western horizon at sunset could see them. That year, a creative photographer traveled away from the town lights of Szubin, Poland to photograph a near closest approach of the two planets. The bright planets were then separated by only three degrees and his daughter struck a humorous pose. A faint red sunset still glowed in the background. Jupiter and Venus are together again this week after sunset, passing within a degree of each other about two days from today.

    Saturn at Night

    spacescience.org/index.php

    Explanation:
    Telescopic views of Saturn and its beautiful rings often make it the star of star parties. But this stunning view of the outer gas gaint planet's rings and night side just isn't possible from telescopes in the vicinity of planet Earth. Peering out from the inner Solar System they can only bring Saturn's day side into view. In fact, this image of Saturn's slender sunlit crescent with the planet's night shadow cast across its broad and complex ring system was captured by the robot spacecraft Cassini. After a seven year long journey from planet Earth, Cassini called Saturn orbit home for 13 years (from 2004 - 2017) before it was directed to dive into the atmosphere of the gas giant on September 15, 2017. This magnificent mosaic is composed of frames recorded by Cassini's wide-angle camera only two days before its grand final plunge. And Saturn's night will not be seen again until another spaceship from Earth calls.

    A Message from Earth

    Explanation:
    What are these Earthlings trying to tell us? The featured message was broadcast from Earth towards the globular star cluster M13 in 1974. During the dedication of an upgrade to the Arecibo Observatory - then the largest single radio telescope in the world - a string of 1's and 0's representing the diagram was sent. This attempt at extraterrestrial communication was mostly ceremonial - humanity regularly broadcasts radio and television signals out into space accidentally. Even were this message received, M13 is so far away we would have to wait almost 50,000 years to hear an answer. The featured message gives a few simple facts about humanity and its knowledge: from left to right are numbers from one to ten, atoms including hydrogen and carbon, some interesting molecules, DNA, a human with description, basics of our Solar System, and basics of the sending telescope. Several searches for extraterrestrial intelligence are currently underway.

    Robert Goddard and Nell
    * Image Credit: Esther Goddard, from the Clark University archive
    clarku.edu/library/archives-an

    Explanation:
    Robert H. Goddard, considered the father of modern rocketry, was born in Worcester Massachusetts in 1882. As a 16 year old, Goddard read H.G. Wells' science fiction classic "War Of The Worlds" and dreamed of space flight. By 1926 he had designed, built, and flown the world's first liquid fuel rocket. Launched 100 years ago on March 16, 1926 from his aunt Effie's farm in Auburn Massachusetts, the rocket, dubbed "Nell," rose to an altitude of 41 feet in a flight that lasted about 2 1/2 seconds. In this posed photo, Goddard stands next to the 10 foot tall rocket, holding the launch stand frame. To achieve a stable flight without the need for fins, the rocket's heavy motor was located at the top, fed by lines from liquid oxygen and gasoline fuel tanks at the bottom. Widely recognized as a gifted experimenter and engineering genius, his rockets were many years ahead of their time. Goddard was awarded over 200 patents in rocket technology, most of them after his death in 1945. A liquid fuel rocket constructed on princip

    Launch Plume: SpaceX Jellyfish
    * Image Credit & Copyright: Michael Seeley
    mseeley.net/
    * Text: Cecilia Chirenti (NASA GSFC, UMCP, CRESST II)
    science.gsfc.nasa.gov/sci/bio/

    Explanation:
    Even if you live with your head in the clouds, you won’t find a jellyfish like this one very often. The featured image shows a SpaceX Falcon 9 rocket launch from Cape Canaveral in Florida on March 4. The launch happened 52 minutes before sunrise, and the second stage rocket exhaust plume was high enough in the sky to catch the light of the rising sun, while the photographer was still in the dark. This combination of light and shadow, possible at dawn or dusk, makes the exhaust, mostly water vapor and carbon dioxide, appear as a glowing cloud. It only looks like it's going down, as the rocket follows the curvature of the Earth on its way to space. A related effect is the twilight phenomenon, which causes colorful contrails sometimes mistaken for UFOs. But, in case you are wondering: real jellyfish were sent to space by NASA in the 1990s as part of a science experiment.

    Explanation:
    Look up this week and see a whole bunch of planets. Just after sunset, looking west (mostly), planets Mercury, Venus, Saturn, and Jupiter will all be visible to the unaided eye simultaneously. If you have a telescope, planets Uranus and Neptune can also be seen. In order up from the horizon, the lineup this week will be Venus (the brightest), Mercury, Saturn, Neptune, Uranus, and Jupiter (second brightest). It doesn't matter where on Earth you live because this early evening planet parade will be visible through clear skies all around the globe. The planets will appear to be nearly in a line because they all orbit the Sun in nearly the same plane: the ecliptic. The featured image shows a similar planet parade that occurred in 2022, captured over the Sydney Opera House in southern Australia. Although visible all week, the planets will be most easily seen together this weekend.

    Explanation:
    Only two days after the February New Moon's annular eclipse of the Sun, a slender lunar crescent poses above the western horizon after sunset in this wintry twilight skyscape. Its nightside faintly illuminated by earthshine, the young Moon is joined by three bright planets in the mostly clear, early evening skies above the village of Kirazli, Turkiye. Inner planet Venus appears closest to the horizon. Near the begininng of its 2026 performance as planet Earth's evening star, brilliant Venus is seen through the warm sunset glare near picture center. Straight above Venus, innermost planet Mercury is easy to spot as it stands remarkably high above the horizon even as the twilight sky is growing dark. Outer planet Saturn, most distant of the naked-eye planets, is found just left of the Moon's sunlit crescent.

    Ice Halos by Moonlight and Sunlight
    * Image Credit & Copyright: Antonella Cicala

    Explanation:
    Both Moon and Sun create beautiful ice halos in planet Earth's sky. In fact, the two brightest celestial beacons are each surrounded by a complex of ice halos in these photos of the sky above Chamonix-Mont-Blanc in France. The panels were recorded one night (left) and the following day at the end of December 2025. Similar ice halos appear in moonlight and sunlight because they are all formed through the geometry of flat, hexagonal ice crystals. The ice crystals reflect and refract light as they flutter in the cold atmosphere above the mountain resort. In the pictures both Moon and Sun are surrounded by a more commonly seen 22 degree circular halo. Bright and sometimes colorful patches at the intersections of the 22 degree circular halos with the indicated parselenic and parhelic arcs are also known as Moon dogs and Sun dogs.

    An Artificial Comet

    Explanation:
    Yes, but can your comet tail do this? No, and what you are seeing is not the tail of a comet. The picture features a cleverly overlayed time-lapse sequence of a group of satellites orbiting Earth together in June. Specifically, these are Starlink communications satellites in low Earth orbit reflecting back sunlight before sunrise to Inner Mongolia, China. Although the satellites appear to the human eye as points, the 20-second-long camera exposures caused them to appear as short streaks. Currently there are over 9000 (!) + Starlinks in orbit, with more being launched nearly every week.
    Other satellite constellations are also being planned.

    Lightning Eclipse from the Planet of the Goats
    * Image Credit & Copyright: Chris Kotsiopoulos (GreekSky)
    greeksky.gr/
    spacetinkerer.com/publications/

    Explanation:
    Thunderstorms almost spoiled this view of the spectacular 2011 June 15 total lunar eclipse. Instead, storm clouds parted for 10 minutes during the total eclipse phase and lightning bolts contributed to the dramatic sky. Captured with a 30-second exposure the scene also inspired one of the more memorable titles (thanks to the astrophotographer) in APOD's now 25-year history. Of course, the lightning reference clearly makes sense, and the shadow play of the dark lunar eclipse was widely viewed across planet Earth in Europe, Africa, Asia, and Australia. The picture itself, however, was shot from the Greek island of Ikaria at Pezi. That area is known as "the planet of the goats" because of the rough terrain and strange looking rocks. The next total lunar eclipse will occur on Wednesday.

    From Wikipedia, the free encyclopedia:

    A keogram
    ("keo" from "Keoeeit" – Inuit word for "Aurora Borealis") is a way of displaying the intensity of an auroral display, taken from a narrow part of a round screen recorded by a camera, more specifically and ideally in practice a "whole sky camera". These images from the narrow band, which usually face up in the north-south orientation in the Northern Hemisphere and the south-north orientation in the Southern Hemisphere, are collected and form a time-dependent graph of the aurora from that part of the sky. This allows one to easily realize the general activity of the display that night, whether it had been interrupted by weather conditions or not, and allows the determination of the regions in which the aurora was seen in terms of latitude and longitude of the area.

    The use of keograms started in the 1970s by Eather et al. to allow a more practical and efficient way of determining the activity of the aurora throughout the recorded night and provide a view of the detailed movements of it, the light of which is also recorded in wavelengths outside of the human visible spectrum. Thus, keograms are also used to analyse the conditions of the equatorial plasma bubbles (EPB) in the ionosphere of the Earth, to estimate its zonal drift at lower latitudes.

    This animation illustrates the construction of a keogram. Keogram image generated from the center column of pixels of 997 sequential RGB images using author's software. Each image was a 2 second exposure. Captured at Midnight Dome, Dawson City (Lat 64.067, Long -139.396), on the night of September 6/7, 2021 using an AurorEye portable all-sky imaging camera. Compressed vertically from a 4000px to 240px height.

    The Sky in 2021
    * Image Credit & Copyright: Cees Bassa (Netherlands Institute for Radio Astronomy)
    planetary.org/profiles/cees-ba
    astron.nl/about/

    Explanation:
    What if you could see the entire sky -- all at once -- for an entire year? That, very nearly, is what is pictured here. Every 15 minutes during 2021, an all-sky camera took an image of the sky over the Netherlands. Central columns from these images were then aligned and combined to create the featured keogram, with January at the top, December at the bottom, and the middle of the night running vertically just left of center. What do we see? Most obviously, the daytime sky is mostly blue, while the nighttime sky is mostly black. The twelve light bands crossing the night sky are caused by the glow of the Moon. The thinnest part of the black hourglass shape occurs during the summer solstice when days are the longest, while the thickest part occurs at the winter solstice. Yesterday was an equinox -- when night and day were equal -- and the northern-spring equinox from one year ago can actually be located in the keogram -- about three-quarters of the way up.

    Solstice on a Spinning Earth

    nasa.gov/
    earthobservatory.nasa.gov/
    nasa.gov/centers/goddard/about

    Explanation:
    Can you tell that today is a solstice by the tilt of the Earth? Yes. At a solstice, the Earth's terminator -- the dividing line between night and day -- is tilted the most. The featured time-lapse video demonstrates this by displaying an entire year on planet Earth in twelve seconds. From geosynchronous orbit, the Meteosat 9 satellite recorded infrared images of the Earth every day at the same local time. The video started at the September 2010 equinox with the terminator line being vertical: an equinox. As the Earth revolved around the Sun, the terminator was seen to tilt in a way that provides less daily sunlight to the northern hemisphere, causing winter in the north. At the most tilt, winter solstice occurred in the north, and summer solstice in the south. As the year progressed, the March 2011 equinox arrived halfway through the video, followed by the terminator tilting the other way, causing winter in the southern hemisphere -- and summer in the north. The captured year ends again with the September equinox, concluding another of the billions of trips the Earth has taken -- and will take
    -- around the Sun.

    19.12.14 at 02.00 PM Peaio’s Bicycle Path (Belluno, Italy).
    The Sun was already behind the mountain.
    Close to the winter solstice.
    They looks like the lines of a car park. They actually are composed of the ice on the road after a short passing of the Sun (less than a hour), leaving the fence’s shadows printed on the ground.
    Surprising natural geometries!

    On February 2015 we found the opposite situation, white and black: the shadow and the snow.

    ragusah24.it/2025/09/12/un-alt

    Explanation:
    The word solstice is from the Latin for Sun and to pause or stand still. And in the days surrounding a solstice the Sun's annual north-south drift in planet Earth's sky does slow down, pause, and then reverse direction. So near the solstice the daily path of the Sun through the sky really doesn't change much. In fact, near the December solstice, the Sun's consistent, low arc through northern hemisphere skies, along with low surface temperatures, has left a noticeable imprint on this road to the mountain town of Peaio in northern Italy. The morning frost on the road has melted away only where the sunlight was able to reach the ground. But it remains in the areas persistently shadowed by the fence, tattooing in frost an image of the fence on the asphalt surface.

    Explanation:
    This is not a screen from a video game. Nestled below the tree-line, the small mountain church does look like it might be hiding from Moon though. In the well-composed telephoto snapshot, taken on November 23, the church walls are partly reflecting light from terrestrial flood lights. Of course, the Moon is reflecting light from the Sun. At any given time the Sun illuminates fully half of the Moon's surface, also known as the lunar dayside, but on that night only a sliver of its sunlit surface was visible. About three days after New Moon, the Moon was in a waxing crescent phase. The single exposure was captured shortly after sunset in skies near Danta di Cadore, northern Italy, planet Earth.

    "A farewell to Mister Eclipse .."

    Dr Fred Espenak (1953–2025)

    by Jay Anderson
    skyandtelescope.org/astronomy-

    The renowned eclipse chaser and popularizer passed away in Arizona after a life of adventure.

    Fred Espenak, who laid the foundation for modern-day eclipse chasing, died of idiopathic pulmonary fibrosis on June 1st. He announced his diagnosis and his impending passing on April 15th on social media and on the Solar Eclipse Message List (SEML) forum as he prepared to enter hospice care, sparking an outpouring of sorrow, sympathy, good wishes, and thank-you’s for his life’s work.

    Fred’s fascination with the lunar shadow began with an off-the-track partial eclipse in 1963 and was cemented several years later by the total solar eclipse that traveled along the U.S. Eastern Seaboard in 1970. Upon his death 55 years later, he had witnessed 52 solar eclipses of various types, of which 31 were total. He had also helped countless others prepare for and experience the wonder of totality, thanks to his dedication to outreach.

    There were many stories along the way, but he was fond of telling of his most rewarding eclipse-chasing experience — a trip to India in 1995 to catch 41 seconds of totality, during which he noticed a high-school chemistry teacher watching her first eclipse. “Nice hair,” he thought. Several eclipses and a decade later, he and Patricia Totten, the lady with the hair, were married. It was a particularly fond pairing, as visitors to his Arizona home could attest.

    Sardinia Sunset
    * Image Credit & Copyright: Lorenzo Busilacchi

    Explanation:
    When the sun sets on September 7, the Full Moon will rise. And on that date denizens around much of our fair planet, including parts of Antarctica, Australia, Asia, Europe, and Africa can witness a total lunar eclipse, with the Moon completely immersed in Earth's shadow. As the bright Full Moon first enters Earth's shadow it will darken, finally taking on a reddish hue during the total eclipse phase. In fact, the color of the Moon during a total lunar eclipse is due to reddened light from sunrises and sunsets around planet Earth. The reddened sunlight is scattered by a dense atmosphere into the planet's otherwise dark central shadow. When the sun set on August 22, this telephoto snapshot of red skies, blue sea, and the Mangiabarche Lighthouse was captured from Sant'Antioco, Sardinia, Italy.

    Partial Solar Eclipse with Airplane
    * Image Credit & Copyright: Phillip Calais

    Explanation:
    It was just eight minutes after sunrise, last week, and already there were four things in front of the Sun. The largest and most notable was Earth's Moon, obscuring a big chunk of the Sun's lower limb as it moved across the solar disk, as viewed from Fremantle, Australia. This was expected as the image was taken during a partial solar eclipse -- an eclipse that left sunlight streaming around all sides of the Moon from some locations. Next, a band of clouds divided the Sun horizontally while showing interesting internal structure vertically. The third intervening body might be considered to be the Earth's atmosphere, as it dimmed the Sun from its higher altitude brightness while density fluctuations caused the Sun's edges to appear to shimmer. Although closest to the photographer, the least expected solar occulter was an airplane. Quite possibly, passengers on both sides of that airplane were contemplating the unusual view only visible out the eastern-facing windows.
