      Kestrel kestrelling by the sea.

      They drag me off-sanctuary once in a while. Sometimes it’s worth it.😂
      Observed this amazing creature hunting along the sea-shore recently.
      A study in the majesty and engineering of nature.
      How perfectly still the head remains…

      Alt...A kestrel hovers hunting. Sea and hills on a far shoreline behind. Breaks hover to move further along the shore and then hovers again. Shot from a cliff-top so that the bird is more or less at eye level.

              Dust Shapes of the Ghost Nebula
              * Image Credit & Copyright: Kent Wood
              ssr.app.astrobin.com/u/kvwood#

              Explanation:
              Do any shapes seem to jump out at you from this interstellar field of stars and dust? The jeweled expanse, filled with faint, starlight-reflecting clouds, drifts through the night in the royal constellation of Cepheus. Far from your own neighborhood on planet Earth, these ghostly apparitions lurk along the plane of the Milky Way at the edge of the Cepheus Flare molecular cloud complex some 1,200 light-years away. Over two light-years across and brighter than the other spooky chimeras, VdB 141 or Sh2-136 is also known as the Ghost Nebula, seen across the middle of the featured image. Within the reflection nebula are the telltale signs of dense cores collapsing in the early stages of star formation.

                                NGC 6995: The Bat Nebula
                                * Image Credit & Copyright: Francis Bozon & Jean-Luc Gangloff

                                Explanation:
                                Can you see the bat? It haunts this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star. While the Veil is roughly circular in shape and covers nearly 3 degrees on the sky toward the constellation of the Swan (Cygnus), NGC 6995, known informally as the Bat Nebula, spans only 1/2 degree, about the apparent size of the Moon. That translates to 12 light-years at the Veil's estimated distance, a reassuring 1,400 light-years from planet Earth. In the composite of image data recorded through several narrow band filters, with emission from hydrogen atoms in the remnant shown in red and with strong emission from oxygen atoms shown in hues of blue. Of course, in the western part of the Veil lies another seasonal apparition: the Witch's Broom Nebula.

                                    Novemberspaziergang ist ein Aquarellgemälde im Hochformat der Künstlerin Karen Kaspar. Es zeigt eine abstrahierte Landschaft mit einem einsamen Baum und der Silhouette zweier gehender Menschen. Der Himmel ist dunkel und Schneeflocken tanzen. Das Gemälde ist nur mit zwei Farben gemalt: Indigoblau und Sienabraun sowie dem Weiß des Papiers. Es war ein trüber, bewölkter Novembertag, als wir unseren Sonntagsspaziergang begannen. Niemand war in der Nähe, alles war ruhig und friedlich, als wir entlang kahler Felder und einsamer Bäume gingen. Plötzlich zogen dunkle Wolken auf und es begann zu schneien. Es war fast wie ein kleiner Schneesturm und als wir endlich unser Auto erreichten, sahen wir aus wie kleine Schneemänner, weil wir überall mit Schnee bedeckt waren. Dieses wundervolle Erlebnis inspirierte mich, dieses abstrakte Landschaftsgemälde in Aquarellfarben zu malen.

                                      Two Tails of Comet Lemmon
                                      * Image Credit: Massimo Penna

                                      Explanation:
                                      How many bright tails does Comet Lemmon have? Two. In the featured image it appears to have three, but why? The reason is that the zigzagging brown filament is a persistent meteor train that by luck appeared in front of the distant comet C/2025 A6 (Lemmon). A meteor train is the hot gas and fine dust that remains in the Earth's atmosphere and disperses in the seconds after a bright meteor flashes by. The two bright tails are the blue ion tail stretching across the image, and the white dust tail nearer the green coma on the upper left. All real comet tails originate from the nucleus of the comet inside the coma. The image was captured a few days ago from Manciano, Italy. This week, from mid-northern locations, Comet Lemmon will remain faintly visible in the northwest sky after sunset.

The two bright tails are the blue ion tail stretching across the image, and the white dust tail nearer the green coma on the upper left. All real comet tails originate from the nucleus of the comet inside the coma. The image was captured a few days ago from Manciano, Italy. This week, from mid-northern locations, Comet Lemmon will remain faintly visible in the northwest sky after sunset.

                                        Explanation:
                                        Comet C/2025 R2 (SWAN) sports a greenish coma and fainter tail, seen against congeries of stars and dusty interstellar clouds in this 7 degree wide telescopic field of view from October 17. On that date, the new visitor to the inner Solar System obligingly posed with two other celestial birds seen toward the center of our Milky Way. Messier 16, near the bottom of the frame, and Messier 17 are also known to deep skywatchers as the Eagle and the Swan nebulae. While the comet coma's greenish glow recorded in the image is due to diatomic carbon gas fluorescing in sunlight, reddish hues seen in the nebulae, star forming regions some 5,000 light-years distant, are characteristic of ionized hydrogen gas. Comet SWAN is outbound now but still a good comet for binoculars and small telescopes that can look close to the southern horizon in the northern hemisphere's early evening skies. C/2025 R2 (SWAN) was closest to our fair planet on October 20, a mere 2.2 light-minutes away.

                                            Halloween and the Ghost Head Nebula

                                            Explanation:
                                            Halloween's origin is ancient and astronomical. Since the fifth century BC, Halloween has been celebrated as a cross-quarter day, a day halfway between an equinox (equal day / equal night) and a solstice (minimum day / maximum night in the northern hemisphere). With a modern calendar however, even though Halloween later this week, the real cross-quarter day will occur the next week. Another cross-quarter day is Groundhog Day. Halloween's modern celebration retains historic roots in dressing to scare away the spirits of the dead. Perhaps a fitting tribute to this ancient holiday is this view of the Ghost Head Nebula taken with the Hubble Space Telescope. Similar to the icon of a fictional ghost, NGC 2080 is actually a star forming region in the Large Magellanic Cloud, a satellite galaxy of our own Milky Way Galaxy. The Ghost Head Nebula (NGC 2080) spans about 50 light-years and is shown in representative colors.

The journey begins with a ground-based image by astrophotographer Akira Fujii, then transitions into a plate from the Digitized Sky Survey. Next a two-color image from the now-retired infrared NASA Spitzer Space Telescope appears, and then finally the video arrives at the James Webb Space Telescope’s image of the star-forming region.

                                                      The star-forming region captured in Webb’s image is small and not particularly active compared to other well-known star-forming regions. It is the region’s proximity to Earth (390 light-years) that allows Webb to capture it in such detail, emphasizing the structure of jets bursting from young solar-mass stars, and a dusty “cave” of glowing polycyclic aromatic hydrocarbons.

                                                        A mere 390 light-years away, Sun-like stars and future planetary systems are forming in the Rho Ophiuchi molecular cloud complex, the closest star-forming region to our fair planet. The James Webb Space Telescope's NIRCam peered into the nearby natal chaos to capture this infrared image at an inspiring scale. The frame spans less than a light-year across the Rho Ophiuchi region and contains about 50 young stars. Brighter stars clearly show Webb's characteristic pattern of diffraction spikes. Huge jets of shocked molecular hydrogen blasting from newborn stars are red in the image, with the large, yellowish dusty cavity carved out by the energetic young star near its center. Near some stars in the stunning image are shadows cast by their protoplanetary disks. The spectacular cosmic snapshot was released in 2023 to celebrate the successful first year of Webb's exploration of the Universe.

About 12,000 light-years away toward the constellation Ophiuchus, the cluster's starlight is dimmed and reddened by the Milky Way's interstellar dust when viewed from planet Earth. As a result, the stars of NGC 6366 look almost golden in this telescopic scene, especially when seen next to relatively bright, bluish, and nearby star 47 Ophiuchi. Compared to the hundred thousand stars or so gravitationally bound in distant NGC 6366, 47 Oph itself is a binary star system a mere 100 light-years away. Still, the co-orbiting stars of 47 Oph are too close together to be individually distinguished in the image.

                                                            Rho Ophiuchi is a multiple star system in the constellation Ophiuchus. The central system has an apparent magnitude of 4.63. Based on the central system's parallax, it is located about 450 light-years distant. The other stars in the system are slightly farther away.

                                                            The central system is known as Rho Ophiuchi AB. It consists of three blue-colored subgiants or main-sequence stars, designated Rho Ophiuchi Aa, Ab and B, respectively. Rho Ophiuchi Aa-Ab is a spectroscopic binary with an orbital period of 88 days and an orbital period of 1.1 astronomical units. Farther away is the B companion, a visual binary whose sky-projected distance from the inner pair appears to be 3.1″, corresponding to a separation of at least 344 AU. However, the actual separation is larger, and the two take about 2,400 years to complete an orbit. The two stars dominate the radiation field around the Rho Ophiuchi cloud complex.

                                                            Rho Ophiuchi A emits X-rays, and exhibits strong variability in emission over periods of about 1.2 days, corresponding to its rotation period. The X-ray variability is due to the strong magnetic field of the secondary companion, Rho Ophiuchi Ab, whose dipole strength is 4 kG.

                                                            Several other stars are located close to Rho Ophiuchi AB. HD 147932 is located 2.5 arcminutes away (at least 17,000 AU), and is known as Rho Ophiuchi C. HD 147888 is located 2.82 arcminutes away (at least 19,000 AU), and is known as Rho Ophiuchi DE.[11] Stars C and D are both B-type main-sequence stars, and D itself is another binary with an orbital period of around 680 years.

Rho Ophiuchi cloud complex (N is up): Antares is the bright star that looks yellow in this image, σ Scorpii is in the red nebula (Sh2-9), and the globular cluster M4 is in between. Rho Ophiuchi is the small group of stars in the blue nebulosity (IC 4604). Rho Ophiuchi is the namesake of the Rho Ophiuchi cloud complex. It is a nebula of gas and dust, which the Rho Ophiuchi system is embedded in. It is one of the easiest star forming regions to observe, as it is one of the nearest, and it is visible from both hemispheres. The interstellar extinction (AV) of Rho Ophiuchi is measured to be 1.45 magnitudes, meaning the dust and gas in front of Rho Ophiuchi absorbs light from the system, making it appear 1.45 magnitudes dimmer than it would be if there were no dust or gas. Additionally, gas and dust also scatters more higher-frequency light, leaving the light appearing more reddish. The interstellar reddening (EB−V) of Rho Ophiuchi has been measured to be 0.47 magnitudes.

The yellow dashed lines are constellation boundaries, the red dashed line is the ecliptic, and the shades of blue show Milky Way areas of different brightness. The map contains all Messier objects, except for colliding ones. The underlying database contains all stars brighter than 6.5. All coordinates refer to equinox 2000.0. The map is calculated with the equidistant azimuthal projection (the zenith being in the center of the image). The north pole is to the top. The (horizontal) lines of equal declination are drawn for 0°, ±10°, ±20° etc. The lines of equal rectascension are drawn for all 24 hours. Towards the rim there is a very slight magnification (and distortion).

                                                                A region that would look black in visible light is revealed in the infrared with Webb sensitive instruments. The detail in Webb's portrait of starbirth is unprecedented. The scene is dominated by a giant cavity that has been carved by a single star. That star, S1, is more massive than our sun and emits ultraviolet photons that have carved out a bubble.

                                                                The yellow orange color comes from tiny sooty grains that astronomers call polycyclic aromatic hydrocarbons. Streamers of gas and dust form structures and textures unlike anything we have seen before. The striking large red vertical band is a protostellar outflow, twin powerful Jets of material that occurred during the early stages of star formation.

                                                                The projecting cone is the result of material that's been ejected through the jet. The entire structure glows red due to molecular hydrogen being energized as material from the jets collides with interstellar gas.

                                                                Like most young stars young solar systems also form in multiples. And we can see several brand new solar systems making their way into the universe via the very same processes that shaped our own cosmic home. Planet forming disks block the star's light casting telltale shadows across space.

The image was taken to celebrate the first anniversary of the start of science operations for NASA’s James Webb Space Telescope. Jets bursting from young stars crisscross the image, impacting the surrounding interstellar gas and lighting up molecular hydrogen, shown in red. Some stars display the telltale shadow of a circumstellar disk, the makings of future planetary systems. Once our entire solar system, encompassing the entire history of life as we know it, would have appeared something like this if seen from a distance. At bottom, a glowing cave of dust dominates the image. It was carved out by the star S1, at the center of the cavity – the only star in the image that is significantly more massive than our Sun. * Video Credits: NASA, ESA, CSA, Greg Bacon (STScI)

                                                                  blasting out of new stars before, the texture that Webb’s NIRCam instrument reveals in the multiple jets crisscrossing the image is unprecedented. In striking contrast, the lower half of the image is dominated by a glowing cave of dust being lit up and eroded by the most massive star in the scene. Its stellar neighbors are the mass of our Sun or smaller, with some displaying the telltale shadows of protoplanetary disks—meaning we are looking at planetary systems potentially similar to our own in their earliest stages.

Here, a high concentration of dust and molecular gas absorb practically all the visible light emitted from background stars. The eerily dark surroundings help make the interiors of molecular clouds some of the coldest and most isolated places in the universe. One of the most notable of these dark absorption nebulae is a cloud toward the constellation Ophiuchus known as Barnard 68, pictured here. That no stars are visible in the center indicates that Barnard 68 is relatively nearby, with measurements placing it about 500 light-years away and half a light-year across. It is not known exactly how molecular clouds like Barnard 68 form, but it is known that these clouds are themselves likely places for new stars to form. In fact, Barnard 68 itself has been found likely to collapse and form a new star system. It is possible to look right through the cloud in infrared light.

Scorpius more typically appears as a few bright stars in a well-known but rarely pointed out zodiacal constellation. To get a spectacular image like this, though, one needs a good camera, color filters, and a digital image processor. To bring out detail, the above image not only involved long duration exposures taken in several colors, but one exposure in a very specific red color emitted by hydrogen. The resulting image shows many breathtaking features. Vertically across the image left is part of the plane of our Milky Way Galaxy. Visible there are vast clouds of bright stars and long filaments of dark dust. Jutting out diagonally from the Milky Way in the image center are dark dust bands known as the Dark River. This river connects to several bright stars on the right that are part of Scorpius' head and claws, and include the bright star Antares. Above and right of Antares is an even brighter planet Jupiter. Numerous red emission nebulas and blue reflection nebulas are visible throughout the image. Scorpius appears prominently in southern skies after sunset during the middle of the year.

At certain times of the year, a band of sun-reflecting dust from the inner Solar System appears prominently just after sunset -- or just before sunrise -- and is called zodiacal light. Although the origin of this dust is still being researched, a leading hypothesis holds that zodiacal dust originates mostly from faint Jupiter-family comets and slowly spirals into the Sun. Recent analysis of dust emitted by Comet 67P, visited by ESA's robotic Rosetta spacecraft, bolsters this hypothesis. Pictured when climbing a road up to Teide National Park in the Canary Islands of Spain, a bright triangle of zodiacal light appeared in the distance soon after sunset. Captured on June 21, 2019, the scene includes bright Regulus, the alpha star of the constellation Leo, standing above center toward the left. The Beehive Star Cluster (M44) can be spotted below center, closer to the horizon and also immersed in the zodiacal glow.

The field of view spans nearly 3 degrees across the nebula-rich constellation Ophiuchus toward the central Milky Way. A Dark Veil of wispy interstellar dust clouds draped across the foreground is chiefly identified as LDN 234 and LDN 204 from the 1962 Catalog of Dark Nebulae by American astronomer Beverly Lynds. Sh2-27 itself is the large but faint HII region surrounding runaway O-type star Zeta Ophiuchi. Along with the Zeta Oph HII region, LDN 234 and LDN 204 are likely 500 or so light-years away. At that distance, this telescopic frame would be about 25 light-years wide.

The field of view spans nearly 3 degrees across the nebula-rich constellation Ophiuchus toward the central Milky Way. A Dark Veil of wispy interstellar dust clouds draped across the foreground is chiefly identified as LDN 234 and LDN 204 from the 1962 Catalog of Dark Nebulae by American astronomer Beverly Lynds. Sh2-27 itself is the large but faint HII region surrounding runaway O-type star Zeta Ophiuchi. Along with the Zeta Oph HII region, LDN 234 and LDN 204 are likely 500 or so light-years away. At that distance, this telescopic frame would be about 25 light-years wide. Authors & editors: Robert Nemiroff (MTU) & Jerry Bonnell (UMCP) NASA Official: Amber Straughn Specific rights apply.

                                                                                    [...] *

(The moons and stars have also been brightened by a factor of 15 in this version.)

                                                                                    The ice-covered moon Enceladus -- home to a global subsurface ocean that erupts into space -- can be seen at the 1 o'clock position. Directly below Enceladus, just outside the F ring (the thin, farthest ring from the planet seen in this image) lies the small moon Epimetheus. Following the F ring clock-wise from Epimetheus, the next moon seen is Janus. At about the 4:30 position and outward from the F ring is Mimas. Inward of Mimas and still at about the 4:30 position is the F-ring-disrupting moon, Pandora. Moving around to the 10 o'clock position, just inside of the F ring, is the moon Prometheus.
