Due to the recent unauthorized publication of my images in a magazine. newspaper and two published books without payment I have to now make this statement. I keep attending online Railway Soc events where speakers brazenly show my images without any acknowledgment of the photographer or the fact they have just stolen them off my FLICKR site. Hence I have been forced to add a copyright sign in the corner.

A portion of the open cluster NGC 6530 appears as a roiling wall of smoke studded with stars in this image from the NASA/ESA Hubble Space Telescope. NGC 6530 is a collection of several thousand stars lying around 4,350 light-years from Earth in the constellation Sagittarius. The cluster is set within the larger Lagoon Nebula, a gigantic interstellar cloud of gas and dust. Hubble has previously imaged the Lagoon Nebula several times, including these images released in 2010 and 2011. It is the nebula that gives this image its distinctly smoky appearance; clouds of interstellar gas and dust stretch from one side of the image to the other.
Astronomers investigated NGC 6530 using Hubble’s Advanced Camera for Surveys and Wide Field Planetary Camera 2. They scoured the region in the hope of finding new examples of proplyds, a particular class of illuminated protoplanetary discs surrounding newborn stars. The vast majority of known proplyds are found in only one region, the nearby Orion Nebula. This makes understanding their origin and lifetimes in other astronomical environments challenging.
Hubble’s ability to observe at near-infrared wavelengths – particularly with Wide Field Camera 3 – have made it an indispensable tool for understanding star birth and the origin of exoplanetary systems. The new NASA/ESA/CSA James Webb Space Telescope’s unprecedented observational capabilities at infrared wavelengths will complement Hubble observations by allowing astronomers to peer through the dusty envelopes around newly born stars and investigate the faintest, earliest stages of star birth.

NGC 4666 takes center stage in this image from the NASA/ESA Hubble Space Telescope. This majestic spiral galaxy lies about 80 million light-years away in the constellation Virgo and is undergoing a particularly intense episode of star formation. Astronomers refer to galaxies that rapidly form stars as starburst galaxies. NGC 4666’s starburst is likely due to gravitational interactions with its unruly neighbors – including the nearby galaxy NGC 4668 and a dwarf galaxy, which is a small galaxy made up of a few billion stars.
NGC 4666’s burst of star formation is driving an unusual form of extreme galactic weather known as a superwind – a gigantic transfer of gas from the bright central heart of the galaxy out into space. This superwind is the result of driving winds from short-lived massive stars formed during NGC 4666’s starburst as well as spectacularly energetic supernova explosions. Two supernovae occurred in NGC 4666 within the last decade – one in 2014 and the other in 2019. The star that led to the 2019 supernova was 19 times as massive as our Sun!
Though the torrent of superheated gas emanating from NGC 4666 is truly vast in scale – extending for tens of thousands of light-years – it is invisible in this image. The superwind’s extremely high temperature makes it stand out as a luminous plume in X-ray or radio observations, but it doesn’t show up at the visible wavelengths imaged by Hubble’s Wide Field Camera 3.

The lazily winding spiral arms of the galaxy NGC 5921 snake across this image from the NASA/ESA Hubble Space Telescope. This galaxy lies approximately 80 million light-years from Earth, and much like our own galaxy, the Milky Way, contains a prominent bar – a central linear band of stars. Roughly half of all spiral galaxies may contain bars. These bars affect their parent galaxies by fueling star formation and influencing the motion of stars and interstellar gas.
Given NGC 5921’s serpentine spiral arms, it seems fitting that the galaxy resides in the constellation Serpens in the northern celestial hemisphere. Serpens is the only one of the 88 modern constellations with two unconnected regions – Serpens Caput (Serpent’s Head) and Serpens Cauda (Serpent’s Tail). Ophiuchus, the Serpent Bearer, separates these two regions.
The scientific study behind this image also came in two parts – observations from Hubble’s Wide Field Camera 3 and observations from the ground-based Gemini Observatory. The two telescopes helped astronomers better understand the relationship between galaxies like NGC 5921 and the supermassive black holes they contain. Hubble’s contribution determined the masses of stars in the galaxies. Hubble also took measurements that helped calibrate the observations from Gemini. Together, Hubble and Gemini provided astronomers with a census of nearby supermassive black holes in a diverse variety of galaxies.

A snapshot of the Tarantula Nebula (also known as 30 Doradus) is featured in this image from the NASA/ESA Hubble Space Telescope. The Tarantula Nebula is a large star-forming region of ionized hydrogen gas that lies 161,000 light-years from Earth in the Large Magellanic Cloud, and its turbulent clouds of gas and dust appear to swirl between the region’s bright, newly formed stars.
The Tarantula Nebula is a familiar site for Hubble. It is the brightest star-forming region in our galactic neighborhood and home to the hottest, most massive stars known. This makes it a perfect natural laboratory in which to test out theories of star formation and evolution, and Hubble has a rich variety of images of this region. The NASA/ESA/CSA James Webb Space Telescope also recently delved into this region, revealing thousands of never-before-seen young stars.
This new image combines data from two different observing proposals. The first was designed to explore the properties of the dust grains that exist in the void between stars that make up the dark clouds winding through this image. This proposal, which astronomers named Scylla, reveals how interstellar dust interacts with starlight in a variety of environments. It complements another Hubble program called Ulysses, which characterizes the stars. This image also incorporates data from an observing program studying star formation in conditions similar to the early universe, as well as cataloging the stars of the Tarantula Nebula for future science with Webb.

Probarona Purnima, the second largest festival of the Buddhist community. It is also known as ‘Ashwini Purnima’.
The word ‘Probarona’ comes from the Sanskrit language. The Pali form of the word ‘Probarona’ is ‘Pobarona’ - means ‘forbidding’, ‘completion of education’, ‘fulfilment of desires’, ‘satisfaction of hope’, ‘acceptance in the right way’, ‘acknowledgment of faults’, etc.
In all, Probarona means accepting the true and good deeds by rejecting the untruthful and unskilled deeds.
The ritual of Probarona is self-purification and accepting the true and the beautiful by rejecting evil. After the attainment of Gautama Buddha, Ashwini celebrated the festival of Probarona at the end of the three-month rainy season from Ashari to the date of the full moon. Since then, the day has been solemnly celebrated in Buddhist culture.
Nestled among the vast clouds of star-forming regions like this one lie potential clues about the formation of our own solar system.
This image from the NASA/ESA Hubble Space Telescope features AFGL 5180, a beautiful stellar nursery located in the constellation of Gemini (the Twins).
At the center of the image, a massive star is forming and blasting cavities through the clouds with a pair of powerful jets, extending to the top right and bottom left of the image. Light from this star is mostly escaping and reaching us by illuminating these cavities, like a lighthouse piercing through the storm clouds.
Stars are born in dusty environments and although this dust makes for spectacular images, it can prevent astronomers from seeing stars embedded in it. Hubble’s Wide Field Camera 3 (WFC3) instrument is designed to capture detailed images in both visible and infrared light, meaning that the young stars hidden in vast star-forming regions like AFGL 5180 can be seen much more clearly.

Absorption nebulae or dark nebulae are clouds of gas and dust that don’t emit or reflect light, but block light coming from behind them. These nebulae tend to contain large amounts of dust, which allows them to absorb visible light from stars or nebulae beyond them. Astronomer William Herschel, discussing these seemingly empty spots in the late 1700s, called them “a hole in the sky.”
These opaque, dark knots of gas and dust called "Bok globules" are absorbing light in the center of the nearby emission nebula and star-forming region, NGC 281. Bok globules may form stars, or may eventually dissipate.

This image shows the spiral galaxy NGC 5037, in the constellation of Virgo. First documented by William Herschel in 1785, the galaxy lies about 150 million light-years away from Earth. Despite this distance, we can see the delicate structures of gas and dust within the galaxy in extraordinary detail. This detail is possible using Hubble’s Wide Field Camera 3 (WFC3), whose combined exposures created this image.
WFC3 is a very versatile camera, as it can collect ultraviolet, visible, and infrared light, thereby providing a wealth of information about the objects it observes. WFC3 was installed on Hubble by astronauts in 2009, during Servicing Mission 4 (SM4). SM4 was Hubble’s final Space Shuttle servicing mission, expected to prolong Hubble’s life for at least another five years. Twelve years later, both Hubble and WFC3 remain very active and scientifically productive.

The subject of this image is a group of three galaxies, collectively known as NGC 7764A. They were imaged by the NASA/ESA Hubble Space Telescope, using both its Advanced Camera for Surveys and Wide Field Camera 3. The two galaxies in the upper right of the image appear to be interacting with one another. The long trails of stars and gas extending from them give the impression that they have both just been struck at great speed, thrown into disarray by the bowling-ball-shaped galaxy to the lower left of the image. In reality, interactions between galaxies happen over very long time periods, and galaxies rarely collide head-on with one another. It is also unclear whether the galaxy to the lower left is interacting with the other two, although they are so relatively close in space that it seems possible that they are. By happy coincidence, the collective interaction between these galaxies has caused the two on the upper right to form a shape, which from our solar system's perspective, resembles the starship known as the USS Enterprise from Star Trek!
NGC 7764A, which lies about 425 million light-years from Earth in the constellation Phoenix, is a fascinating example of just how awkward astronomical nomenclature can be. The three galaxies are individually referred as NGC 7764A1, NGC 7764A2, and NGC 7764A3. This rather haphazard naming makes more sense when we consider that many astronomical catalogs were compiled well over 100 years ago, long before modern technology made standardizing scientific terminology much easier. As it is, many astronomical objects have several different names, or might have names that are so similar to other objects’ names that they cause confusion.

I didn't realize that the piece of paper the guy from Rock-Serwis gave me would be the most precious thing I have ever got.
I think it was acknowledgment list from Steven Wilson to R-S for support, following in Poland and organising concerts.
By the way, I still have got tears in eyes.
Thank you.
The narrow galaxy elegantly curving around its spherical companion in this image is a fantastic example of a truly strange and very rare phenomenon! 💫 👀
This image, taken with NASA's Hubble Space Telescope depicts GAL-CLUS-022058s. GAL-CLUS-022058s is the largest and one of the most complete Einstein rings ever discovered in our universe. The object has been nicknamed by astronomers studying this Einstein ring as the "Molten Ring," which alludes to its appearance and host constellation.
First theorized to exist by Einstein in his general theory of relativity, this object’s unusual shape can be explained by a process called gravitational lensing, which causes light shining from far away to be bent and pulled by the gravity of an object between its source and the observer.
In this case, the light from the background galaxy has been distorted into the curve we see by the gravity of the galaxy cluster sitting in front of it. The near exact alignment of the background galaxy with the central elliptical galaxy of the cluster, seen in the middle of this image, has warped and magnified the image of the background galaxy into an almost perfect ring. The gravity from other galaxies in the cluster causes additional distortions.
Objects like these are the ideal laboratories in which to study galaxies that are often too faint and distant to otherwise see without gravitational lensing.

The mass of dust and bright swirls of stars in this image are the distant galaxy merger IC 2431, which lies 681 million light-years from Earth in the constellation Cancer. The NASA/ESA Hubble Space Telescope has captured what appears to be a triple galaxy merger in progress, as well as a tumultuous mixture of star formation and tidal distortions caused by the gravitational interactions of this galactic trio. A thick cloud of dust obscures the center of this image – though light from a background galaxy is piercing its outer extremities. This image is from a series of Hubble observations investigating weird and wonderful galaxies found by the Galaxy Zoo citizen science project.

The brightest stars embedded in nebulae throughout our galaxy pour out a torrent of radiation that eats into vast clouds of hydrogen gas – the raw material for building new stars. This etching process sculpts a fantasy landscape where human imagination can see all kinds of shapes and figures. This nebula in the constellation of Cassiopeia has flowing veils of gas and dust that have earned it the nickname "Ghost Nebula."
Officially known as IC 63, this nebula is located 550 light-years away in the constellation Cassiopeia the Queen.

Resting on the tail of the Great Bear in the constellation of Ursa Major lies NGC 5585, a spiral galaxy that is more than it appears.
The many stars and clouds of dust and gas that make up NGC 5585, shown here in this Hubble image, contribute only a small fraction of the total mass of the galaxy. As in many galaxies, this discrepancy can be explained by the abundant yet seemingly invisible presence of dark matter, a mysterious material that astronomers can’t directly observe.
The stellar disk of the galaxy extends over 35,000 light-years across. When compared with galaxies of a similar shape and size, NGC 5585 stands out by having a notably different composition. Contributing to the total mass of the galaxy, it contains a far higher proportion of dark matter.
Hot spots of star formation can be seen along the galaxy’s faint spiral arms. These regions shine a brilliant blue, contrasting strikingly against the ever-black background of space.

The twisting patterns created by the multiple spiral arms of NGC 2835 create the illusion of an eye. This is a fitting description, as this magnificent galaxy resides near the head of the southern constellation of Hydra, the water snake. This stunning barred spiral galaxy, with a width of just over half that of the Milky Way, is brilliantly featured in this image taken by the NASA/ESA Hubble Space Telescope. Although it cannot be seen in this image, a supermassive black hole with a mass millions of times that of our Sun is known to nestle in the very center of NGC 2835.
This galaxy was imaged as part of PHANGS-HST, a large galaxy survey with Hubble that aims to study the connections between cold gas and young stars in a variety of galaxies in the local universe. Within NGC 2835, this cold, dense gas produces large numbers of young stars within large star formation regions. The bright blue areas, commonly observed in the outer spiral arms of many galaxies, show where near-ultraviolet light is being emitted more strongly, indicating recent or ongoing star formation.

MY FRIENDS,WISH YOU A PEACEFUL WEEK!
Hugs AM:=)
Darchor (vertical) prayer flags are usually large single rectangles attached to poles along their vertical edge. Darchor are commonly planted in the ground, mountains, cairns, and on rooftops.
Traditionally, prayer flags are used to promote peace, compassion, strength, and wisdom. Its believed the prayers and mantras will be blown by the wind to spread the good will and compassion into all pervading space.
Therefore, prayer flags are thought to bring benefit to all.
By hanging flags in high places they will carry the blessings depicted on the flags to all beings. As wind passes over the surface of the flags which are sensitive to the slightest movement of the wind, the air is purified and sanctified by the Mantras.
The prayers of a flag become a permanent part of the universe as the images fade from exposure to the elements. Just as life moves on and is replaced by new life, Tibetans renew their hopes for the world by continually mounting new flags alongside the old. This act symbolizes a welcoming of life's changes and an acknowledgment that all beings are part of a greater ongoing cycle.
Because the symbols and mantras on prayer flags are sacred, they should be treated with respect. They should not be placed on the ground or used in clothing. Old prayer flags should be burned.
While the pastel tones and fine texture of this image may bring to mind brush strokes on an artist’s canvas, they are in fact a visualisation of data from ESA’s Planck satellite. The image portrays the interaction between interstellar dust in the Milky Way and the structure of our Galaxy’s magnetic field.
Between 2009 and 2013, Planck scanned the sky to detect the most ancient light in the history of the Universe – the cosmic microwave background. It also detected significant foreground emission from diffuse material in our Galaxy which, although a nuisance for cosmological studies, is extremely important for studying the birth of stars and other phenomena in the Milky Way.
Among the foreground sources at the wavelengths probed by Planck is cosmic dust, a minor but crucial component of the interstellar medium that pervades the Galaxy. Mainly gas, it is the raw material for stars to form.
Interstellar clouds of gas and dust are also threaded by the Galaxy’s magnetic field, and dust grains tend to align their longest axis at right angles to the direction of the field. As a result, the light emitted by dust grains is partly ‘polarised’ – it vibrates in a preferred direction – and, as such, could be caught by the polarisation-sensitive detectors on Planck.
Scientists in the Planck collaboration are using the polarised emission of interstellar dust to reconstruct the Galaxy’s magnetic field and study its role in the build-up of structure in the Milky Way, leading to star formation.
In this image, the colour scale represents the total intensity of dust emission, revealing the structure of interstellar clouds in the Milky Way. The texture is based on measurements of the direction of the polarised light emitted by the dust, which in turn indicates the orientation of the magnetic field.
This image shows the intricate link between the magnetic field and the structure of the interstellar medium along the plane of the Milky Way. In particular, the arrangement of the magnetic field is more ordered along the Galactic plane, where it follows the spiral structure of the Milky Way. Small clouds are seen just above and below the plane, where the magnetic field structure becomes less regular.
From these and other similar observations, Planck scientists found that filamentary interstellar clouds are preferentially aligned with the direction of the ambient magnetic field, highlighting the strong role played by magnetism in galaxy evolution.
The emission from dust is computed from a combination of Planck observations at 353, 545 and 857 GHz, whereas the direction of the magnetic field is based on Planck polarisation data at 353 GHz.

This stunning image by the NASA/ESA Hubble Space Telescope features the spiral galaxy NGC 5643 in the constellation of Lupus (the Wolf). Looking this good isn’t easy; 30 different exposures, for a total of nine hours of observation time, together with the high resolution and clarity of Hubble, were needed to produce an image of such high level of detail and beauty.
NGC 5643 is about 60 million light-years away from Earth and has been the host of a recent supernova event (not visible in this latest image). This supernova (2017cbv) was a specific type in which a white dwarf steals so much mass from a companion star that it becomes unstable and explodes. The explosion releases significant amounts of energy and lights up that part of the galaxy.
The observation was proposed by Adam Riess, who (alongside Saul Perlmutter and Brian Schmidt) was awarded a Nobel Prize in physics in 2011 for his contributions to the discovery of the accelerating expansion of the universe.

This NASA Hubble Space Telescope photo of NGC 7714 presents an especially striking view of the galaxy's smoke-ring-like structure. The golden loop is made of sun-like stars that have been pulled deep into space, far from the galaxy's center. The galaxy is located approximately 100 million light-years from Earth in the direction of the constellation Pisces.
The universe is full of such galaxies that are gravitationally stretched and pulled and otherwise distorted in gravitational tug-o'-wars with bypassing galaxies.
The companion galaxy doing the "taffy pulling" in this case, NGC 7715, lies just out of the field of view in this image. A very faint bridge of stars extends to the unseen companion. The close encounter has compressed interstellar gas to trigger bursts of star formation seen in bright blue arcs extending around NGC 7714's center.
The gravitational disruption of NGC 7714 began between 100 million and 200 million years ago, at the epoch when dinosaurs ruled the Earth.
The image was taken with the Wide Field Camera 3 and the Advanced Camera for Surveys in October 2011.

This image shows galaxy NGC 5033’s spiral arms, dotted with blue clusters of hot, young stars still forming, while older, cooler stars populate the galaxy’s center causing it to appear redder.
NASA’s Hubble Space Telescope captured this closeup of spiral galaxy NGC 5033, which lives about 40 million light-years away in the constellation of Canes Venatici (the Hunting Dogs). The galaxy is similar in size to our own galaxy, the Milky Way, at just over 100,000 light-years across.
Unlike our Milky Way, NGC 5033 is missing a central bar. Instead, it has a bright and energetic core called an active galactic nucleus, powered by a supermassive black hole. This active nucleus gives it the classification of a Seyfert galaxy. Due to the ongoing activity, the core of NGC 5033 shines brightly across the entire electromagnetic spectrum. This released energy shows that the central black hole is currently devouring stars, dust and gas getting close to it.
While its relative proximity to Earth makes it an ideal target for professional astronomers to study its active nucleus in more detail, its big apparent size in the night sky and its brightness also make it a beautiful target for amateur astronomers.

Located around 5,000 light-years away in the constellation of Cygnus (the Swan), Abell 78 is an unusual type of planetary nebula.
After exhausting the nuclear fuel in their cores, stars with a mass of around 0.8 to eight times the mass of our Sun collapse to form dense and hot white dwarf stars. As this process occurs, the dying star will throw off its outer layers of material, forming an elaborate cloud of gas and dust known as a planetary nebula. This phenomenon is not uncommon, and planetary nebulae are a popular focus for astrophotographers because of their often beautiful and complex shapes. However, a few like Abell 78 are the result of a so-called “born again” star.
Although the core of the star has stopped burning hydrogen and helium, a thermonuclear runaway at its surface ejects material at high speeds. This ejecta shocks and sweeps up the material of the old nebula, producing the filaments and irregular shell around the central star seen in this image, which features data from Hubble’s Wide Field Camera 3 and the Panoramic Survey Telescope and Rapid Response System.

In 1959 Derek Chaplin accompanied BBC broadcaster Wynford Vaughan Thomas making a radio broadcast catching trains only from Cardiff to North Wales and calling in on both the embryonic Talyllyn and Ffestiniog railways. Subsequently, Derek made up a 35mm slide show called " Trains of Wales 1959" which he showed at railway societies. These 137 mainly Kodachrome slides have been found by his family preserved in a dry wooden storage box and I am privileged to scan them for people to see again. The notes on each slide are minimalist and with no actual dates so anybody who can add interesting information is appreciated.

The galaxy known as NGC 5907 stretches wide across this image. Appearing as an elongated line of stars and dark dust, the galaxy is categorized as a spiral galaxy just like our own Milky Way. In this new image from the NASA/ESA Hubble Space Telescope, we don’t see the beautiful spiral arms because we are viewing it edge-on, like looking at the rim of a plate. It is for this reason that NGC 5907 is also known as the Knife Edge galaxy.
The Knife Edge galaxy is about 50 million light-years from Earth, lying in the northern constellation of Draco. Although not visible in this image, ghostly streams of stars on large arching loops extend into space, circling around the galaxy; they are believed to be remnants of a small dwarf galaxy, torn apart by the Knife Edge galaxy and merged with it over 4 billion years ago.

Nestled among the vast clouds of star-forming regions like this one lie potential clues about the formation of our own solar system.
This image from the NASA/ESA Hubble Space Telescope features AFGL 5180, a beautiful stellar nursery located in the constellation of Gemini (the Twins).
At the center of the image, a massive star is forming and blasting cavities through the clouds with a pair of powerful jets, extending to the top right and bottom left of the image. Light from this star is mostly escaping and reaching us by illuminating these cavities, like a lighthouse piercing through the storm clouds.
Stars are born in dusty environments and although this dust makes for spectacular images, it can prevent astronomers from seeing stars embedded in it. Hubble’s Wide Field Camera 3 (WFC3) instrument is designed to capture detailed images in both visible and infrared light, meaning that the young stars hidden in vast star-forming regions like AFGL 5180 can be seen much more clearly.

In 1959 Derek Chaplin accompanied BBC broadcaster Wynford Vaughan Thomas making a radio broadcast catching trains only from Cardiff to North Wales and calling in on both the embryonic Talyllyn and Ffestiniog railways. Subsequently, Derek made up a 35mm slide show called " Trains of Wales 1959" which he showed at railway societies. These 137 mainly Kodachrome slides have been found by his family preserved in a dry wooden storage box and I am privileged to scan them for people to see again. The notes on each slide are minimalist and with no actual dates so anybody who can add interesting information is appreciated.

Some of the most stunning views of our sky occur at sunset, when sunlight pierces the clouds, creating a mixture of bright and dark rays formed by the clouds' shadows and the beams of light scattered by the atmosphere.
Astronomers studying nearby galaxy IC 5063 are tantalized by a similar effect in images taken by NASA's Hubble Space Telescope. In this case, a collection of narrow bright rays and dark shadows is seen beaming out of the blazingly bright center of the active galaxy.

You'll probably think I've lost a few marbles in sharing this image and I would be the first to agree with you that it does not suit Flickr, the compressed resolution certainly doesn't do it justice and mobile users will most likely thumb right past with barely a glance. And possibly those with larger screens too.
In my eyes, however, I'm inexplicably attracted to this type of image. The original raw file tack sharp with detail in the tree bark, colours perfect with a hint of pink in the sky and sand dunes a glowing burnt orange, the centre tree bent slightly in acknowledgment to the two distant trees and more than a generous amount of spacing for all its small elements to make up a composition that pleases me no end. Well, almost.. that there pylon on the right could have been better placed if it had been slightly to the left but I suppose you can't have it all. Except with Photoshop of which I know all of 3 buttons, barely enough to remove a blemish yet alone a pylon intertwined with branches!
The story is a typical late Friday afternoon in the UAE desert, the small crowd of youngsters on the left most likely all from the same family surrounding a rather scary looking fat wheeled desert motorbike, the 4x4s on the right finally being able to let off steam with all rules of the road left behind in their dust trails and most of all, the dark tree shapes and their alignment with the telegraph wires (fine.. power cables!).
Admittedly, this is probably two images instead of one but I love being able to make a step when viewing a large print in order to see the other end! If anyone is familiar with Nick Carver's youtube channel and in particular the 'liquor store' and 'desert sail boat' editions you will know where I'm coming from with his love for what may appear as fairly mundane panoramic scenes but in which the small details turn the scene into a storyboard frame.
Thank you if you did decide to stop here :)

At first glance, this cosmic kaleidoscope of purple, blue and pink offers a strikingly beautiful — and serene — snapshot of the cosmos. However, this multi-coloured haze actually marks the site of two colliding galaxy clusters, forming a single object known as MACS J0416.1-2403 (or MACS J0416 for short).
MACS J0416 is located about 4.3 billion light-years from Earth, in the constellation of Eridanus. This new image of the cluster combines data from three different telescopes: the NASA/ESA Hubble Space Telescope (showing the galaxies and stars), the NASA Chandra X-ray Observatory (diffuse emission in blue), and the NRAO Jansky Very Large Array (diffuse emission in pink). Each telescope shows a different element of the cluster, allowing astronomers to study MACS J0416 in detail.
As with all galaxy clusters, MACS J0416 contains a significant amount of dark matter, which leaves a detectable imprint in visible light by distorting the images of background galaxies. In this image, this dark matter appears to align well with the blue-hued hot gas, suggesting that the two clusters have not yet collided; if the clusters had already smashed into one another, the dark matter and gas would have separated. MACS J0416 also contains other features — such as a compact core of hot gas — that would likely have been disrupted had a collision already occurred.
Together with five other galaxy clusters, MACS J0416 is playing a leading role in the Hubble Frontier Fields programme, for which this data was obtained. Owing to its huge mass, the cluster is in fact bending the light of background objects, acting as a magnifying lens. Astronomers can use this phenomenon to find galaxies that existed only hundreds of million years after the big bang.

He stopped suddenly, RT-1979 didn’t know why. “You two go scout ahead, I’m going over there. Don’t follow me if ya know what’s good for ya.”

I had worked with a few other Bounty Hunters, but this guy was different. No finesse, no tricks, no stealth. Just guns and explosions. Well others might be interested in bring in their bounties alive, he seemed to be quite happy collecting the lesser fees for them dead. I kind of liked it, less data work, less chance of them kill us.
The Empire hires out bounty hunters sparingly, but I’d volunteer to work with this guy again...
This image taken by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3) shows a beautiful spiral galaxy called NGC 6744. At first glance, it resembles our Milky Way albeit larger, measuring more than 200,000 light-years across compared to a 100,000-light-year diameter for our home galaxy.
NGC 6744 is similar to our home galaxy in more ways than one. Like the Milky Way, NGC 6744 has a prominent central region packed with old yellow stars. Moving away from the galactic core, one can see parts of the dusty spiral arms painted in shades of pink and blue; while the blue sites are full of young star clusters, the pink ones are regions of active star formation, indicating that the galaxy is still very lively.
In 2005, a supernova named 2005at (not visible in this image) was discovered within NGC 6744, adding to the argument of this galaxy’s liveliness. SN 2005at is a Type Ic supernova, formed when a massive star collapses on itself and loses its hydrogen envelope.

L'acte de commémoration de Manouchian et de son groupe au Panthéon est censé transcender la politique et célébrer l'universalité de la lutte contre l'oppression.
Mais cet hommage vient d'un gouvernement qui n'est pas du tout en phase avec les valeurs défendues par Manouchian. Le gouvernement français a récemment (2024) mis en place une loi visant à réprimer l'immigration, n'hésitant pas à s'allier à l'extrême droite pour tenter d'imposer des mesures contraires aux droits humains, notamment à l'égard des immigrés malades ou des enfants étrangers dormant dans la rue.
J'ai pris cette photo il y a quelques années à proximité de la grande fresque murale dédiée à Manouchian dans le 20e arrondissement de Paris.

Missak Manouchian, an Armenian Communist activist of "the Immigrant workforce", honored today at the french Panthéon mausoleum for his role in the French Resistance during WWII.
Leading a diverse group of around twenty foreign fighters, Manouchian's operations against Nazi forces in France stand as a testament to international solidarity in the face of tyranny.
The act of commemorating Manouchian and his group at the Panthéon is supposed to transcend mere historical acknowledgment; and is supposed to celebrate the universality of the struggle against oppression.
But this tribute comes from a government that is not at all in line with the values defended by Manoukian. The French government has recently (2024) implemented a law aimed at repressing immigration, not hesitating to ally itself with the extreme right in an attempt to impose measures that run counter to human rights, particularly with regard to sick immigrants or foreign children sleeping rough.

Army Capt. Humayun Khan became a household name when his Gold Star parents spoke at the Democratic National Convention earlier this year, just to be attacked by then presidential candidate Donald Trump.
A lawyer and a reserve officer, Captain Khan died a hero's death for his elected homeland, saving the lives of those under his command.
But had it not been for the misguided decision to invade Iraq, he would probably still lead a happy life back home with his family.
Let's hope that SOMEthing good comes out of this horrible election: no more lives sacrificed on foreign battlegrounds for no reason. Under hawkish Clinton, tens of thousands might have been deployed to Syria to guarantee a no-fly zone.
And common acknowledgment that Muslims, just like any other ethnic, racial, religious group are making a valuable contribution to protect our freedoms and making this country a better place.
Victimizing a group is fascist behavior, and should be met with immediate resistance from all others.
Says the German. We have some experience with this.
Pictured here is the captivating galaxy NGC 2525. Located nearly 70 million light-years from Earth, this galaxy is part of the constellation of Puppis in the southern hemisphere. Together with the Carina and the Vela constellations, it makes up an image of the Argo from ancient greek mythology.
Another kind of monster, a supermassive black hole, lurks at the centre of NGC 2525. Nearly every galaxy contains a supermassive black hole, which can range in mass from hundreds of thousands to billions of times the mass of the Sun.
Hubble has captured a series of images of NGC2525 as part of one of its major investigations; measuring the expansion rate of the Universe, which can help answer fundamental questions about our Universe’s very nature. ESA/Hubble has now published a unique timelapse of this galaxy and it’s fading supernova.

While appearing as a delicate and light veil draped across the sky, this image from the NASA/ESA Hubble Space Telescope actually depicts a small section of the Cygnus supernova blast wave, located around 2,400 light-years away. The name of the supernova remnant comes from its position in the northern constellation of Cygnus (the Swan), where it covers an area 36 times larger than the full Moon.
The original supernova explosion blasted apart a dying star about 20 times more massive than our Sun between 10,000 and 20,000 years ago. Since then, the remnant has expanded 60 light-years from its center. The shockwave marks the outer edge of the supernova remnant and continues to expand at around 220 miles per second. The interaction of the ejected material and the low-density interstellar material swept up by the shockwave forms the distinctive veil-like structure seen in this image.

First of all the acknowledgment to Michael Davies, who did it first, and best. Second this isn't quite where we want it yet. It is supposed to be a levitation photo but there isn't enough separation between Leah and the rocks behind her.

"Traditionally, prayer flags are used to promote peace, compassion, strength, and wisdom. The Tibetans believe the prayers and mantras will be blown by the wind to spread the good will and compassion into all pervading space.(..)
The prayers of a flag become a permanent part of the universe as the images fade from exposure to the elements. Just as life moves on and is replaced by new life, Tibetans renew their hopes for the world by continually mounting new flags alongside the old. This act symbolizes a welcoming of life's changes and an acknowledgment that all beings are part of a greater ongoing cycle."

"Sur les cols, les éperons rocheux, les maisons, les temples, etc., il est de tradition chez les adeptes du bouddhisme tibétain, de hisser et d'arrimer des cordelettes munies de drapeaux de prières tout neufs. Le vent qui caresse au passage les formules sacrées imprimées sur les drapeaux et les disperse dans l’espace, est censé leur donner vie et les transmettre ainsi aux dieux et à tous ceux qu'il touche dans sa course"
Friendly game of dominos in Havana Vieja.In 2013, UNESCO recognized the cultural significance of Cuban dominoes by inscribing it on the Representative List of the Intangible Cultural Heritage of Humanity. This acknowledgment highlighted the game's role in fostering social bonds, preserving traditions, and promoting a sense of identity and continuity among the Cuban people.
Today, dominoes remain an integral part of Cuban life, with the distinct sound of shuffling tiles and lively banter echoing through the streets. It serves as a reminder of the resilience, camaraderie, and cultural pride that define the Cuban spirit.
At first glance, this NASA/ESA Hubble Space Telescope image seems to show an array of different cosmic objects, but the speckling of stars shown here actually forms a single body — a nearby dwarf galaxy known as Leo A. Its few million stars are so sparsely distributed that some distant background galaxies are visible through it. Leo A itself is at a distance of about 2.5 million light-years from Earth and a member of the Local Group of galaxies; a group that includes the Milky Way and the well-known Andromeda galaxy.
Astronomers study dwarf galaxies because they are very numerous and are simpler in structure than their giant cousins. However, their small size makes them difficult to study at great distances. As a result, the dwarf galaxies of the Local Group are of particular interest, as they are close enough to study in detail.
As it turns out, Leo A is a rather unusual galaxy. It is one of the most isolated galaxies in the Local Group, has no obvious structural features beyond being a roughly spherical mass of stars, and shows no evidence for recent interactions with any of its few neighbors. However, the galaxy’s contents are overwhelmingly dominated by relatively young stars, something that would normally be the result of a recent interaction with another galaxy. Around 90% of the stars in Leo A are less than eight billion years old — young in cosmic terms! This raises a number of intriguing questions about why star formation in Leo A did not take place on the “usual” timescale, but instead waited until it was good and ready.

The galaxy UGCA 193, seen here by the NASA/ESA Hubble Space Telescope, is a galaxy in the constellation of Sextans (the Sextant). Looking rather like a waterfall, UGCA 193 appears to host many young stars, especially in the lower portion of this view, creating a striking blue haze and the sense that the stars are falling from “above.”
The blue color of UGCA 193 indicates the stars that we see are hot — some more than six times hotter than our Sun. We know that cooler stars appear to our eyes as redder, and hotter stars appear bluer. A star’s surface temperature and color are also linked to its mass, with heavier stars “burning” at higher temperatures, resulting in a blue glow from their surfaces.

There’s something timeless in the gesture of a hand touching a hat. It speaks to acknowledgment, a deliberate act of saying, “I see you.” It’s a gesture that feels like it belongs to a slower world, one where moments of recognition were cherished and routine. The touch of the hat becomes a symbol—a reminder of the quiet, fleeting connections we make with others. In a hurried world, these moments have become rare, almost relics of another time.
But even as life speeds up, there’s still room for that kind of magic. The gesture doesn’t have to be a literal one. The meaning behind it—“I see you, and you matter”—can take on countless forms. A smile in passing, a kind word, a moment of eye contact. These small things can be profound acts of acknowledgment, of being present, even if just for a breath of a second.
The lights, twinkling like stars, hint at how these small moments of connection shine amidst the blur of daily life. They’re easy to overlook, but they can linger in memory, grounding us in the shared beauty of being human. There’s magic in these gestures, even when—or perhaps especially when—they’re fleeting. We just have to look for them.
Hello
This infrared image from the NASA/ESA Hubble Space Telescope shows the centre of the Milky Way, 27 000 light-years away from Earth. Using the infrared capabilities of Hubble, astronomers were able to peer through the dust which normally obscures the view of this interesting region. At the centre of this nuclear star cluster — and also in the centre of this image — the Milky Way’s supermassive black hole, known as Sagittarius A*, is located.
Sagittarius A* is not the only mystery lurking in this part of the galaxy. The crowded centre contains numerous objects that are hidden at visible wavelengths by thick clouds of dust in the galaxy's disc. In order to truly understand the central part of our galaxy astronomers used the infrared vision of Hubble to peer through this obscuring dust. To reveal the image in all its glory the scientists then assigned visible colours to the different wavelengths of infrared light, which is invisible to human eyes.
The blue stars in the image are foreground stars, which are closer to Earth than the nuclear star cluster, whilst the red stars are either behind much more intervening dust, or are embedded in dust themselves. Some extremely dense clouds of gas and dust are seen in silhouette, appearing dark against the bright background stars. These clouds are so thick that even Hubble's infrared capability cannot penetrate them. In addition to the stars hidden by the dust astronomers estimate that there are about 10 million stars in the cluster which are too faint to see, even for Hubble.
