A beautiful galactic dance 211 million light years away. Captured by Hubble WFC3 and processed by me.
La galaxie spirale NGC 634 (Hubble) est située à 217 millions d'années-lumière de la Terre dans la constellation du Triangle (Triangulum). La finesse des détails et la structure spirale exceptionnellement parfaite de la galaxie en ont fait une cible d'observation privilégiée suite à la disparition violente d'une naine blanche. La supernova de type Ia SN2008a y avait ainsi été repérée et brièvement rivalisé d'éclat avec la galaxie hôte.
Les naines blanches constituent le point final de l'évolution des étoiles dont la masse se situe entre 0,07 et 8 masses solaires, soit 97 % des étoiles de la Voie lactée. Avec toutefois des exceptions, dans un système binaire une naine blanche peut accréter la matière provenant de son étoile compagnon et prendre progressivement du poids. Mais l'étoile peut finir par devenir trop pleine, lorsqu'elle dépasse 1,38 masse solaire. Des réactions nucléaires se déclenchent en produisant d'énormes quantités d'énergie et l'étoile explose en supernova de type Ia.
Cette image a été créée à partir d'images prises avec le canal grand champ de la caméra avancée de Hubble. Ces images ont été obtenues à travers un filtre jaune (F555W, coloré en bleu), combinées avec celles images obtenues à travers des filtres rouge (F625W, coloré en vert) et proche infrarouge (F775W, coloré en rouge). Les temps d'exposition totaux par filtre étaient respectivement de 3 750 s, 3 530 s et 2 484 s, et le champ de vision de 2,5 x 1,5 minute d'arc, soir 0,062° (cf. ESA/Hubble et NASA).

It's Dog Day Monday again! I can't believe another week has flown bye.
Meet Hubble. All I know is that he was not named after the space station or Edwin Hubble after whom the space station was named. Hubble was a loveable, happy-go-lucky Welsh Corgi that lived right around the corner from us until he and his owners moved out of the Bay Area in 2014. Every time I'd meet him, he'd "smile." Don't get the idea that every dog I'm going to show you is smiling. I'm getting into the more serious group and then, just plain old. And, you know, we get grumpy as dogs, especially the two who I'll be showing you in a few weeks that were 17 when I met them.
Anyway, Happy Dog Day Monday #19. Any day with a dog is a happy one (a gross exaggeration, but not as exaggerated as any day without a dog isn't half as great as a day with one). When you unravel that, go rescue a dog.
Cats are okay, too, but from what I've seen on You Tube (and at my nephew's home), they are usually cantankerous, shredding rugs and couches, and love to throw things off countertops. So do parrots, but at least a parrot will talk to you while you're trying to correct them. Our cockatiel used to sing all the radio commercials he'd learned from the radio while we went to school. That was 61 years ago. My favorite, "Where there's Life, there's Lucky Strikes!"
Hubble rocks out with heavy metal stars!
This 10.5-billion-year-old globular cluster, NGC 6496, is home to heavy-metal stars of a celestial kind! The stars comprising this spectacular spherical cluster are enriched with much higher proportions of metals — elements heavier than hydrogen and helium are curiously known as metals in astronomy — than stars found in similar clusters.
A handful of these high-metallicity stars are also variable stars, meaning that their brightness fluctuates over time. NGC 6496 hosts a selection of long-period variables — giant pulsating stars whose brightness can take up to, and even over, a thousand days to change — and short-period eclipsing binaries, which dim when eclipsed by a stellar companion.
The nature of the variability of these stars can reveal important information about their mass, radius, luminosity, temperature, composition, and evolution, providing astronomers with measurements that would be difficult or even impossible to obtain through other methods.
NGC 6496 was discovered in 1826 by Scottish astronomer James Dunlop. The cluster resides at about 35,000 light-years away in the southern constellation of Scorpius (The Scorpion).

… no not the space telescope, the (T)Oil and Trouble one.
Another quick on for Sliders Sunday. I am working on a couple of sets as project, but neither is near enough to completion to share, and time is limited for me just now.
Never one to throw away images (though I am trying to learn how) I have repurposed one of my oil droplet images from Smile on Saturday’s project yesterday. The starting image had lots of detail and texture and a little bit of colour variation from using two oils (see the comment from yesterday for more if you wish).
The work was done mainly in Affinity though I did us a bit of Nik Color Efex to tweak it a bit at the end.
The basic approach takes an oft-travelled path for me. Duplicate the image layer, flip it horizontally and vertically to give the overall result some symmetry and blend the two layers together with Difference blend mode (or any other mode that works for you) which injects lots of colours. The rest is just tweaking the colours.
I’ll post a link to the in-camera image so you can see the rather bland (in comparison) starting point.
Thanks for taking the time to look. I hope you enjoy the image. Happy Sliders Sunday :)
The Hubble Space telescope's observations of the universe have seldom produced more intriguing images than that seen in this section of bubble glass in the window of a public house.
Lors du lancement du télescope spatial Hubble il y a 35 ans, personne n'aurait pu imaginer à quel point il allait transformer notre vision de l'espace. Lancé le 24 avril 1990, le télescope poursuit aujourd'hui sa mission. Pour célébrer son anniversaire, la NASA a publié quatre images récentes prises par Hubble, qui prouvent sa pérennité, même après trois décennies !
°°°°°°°°°
When the launched 35 years ago, no one would have guessed how much it would shape the way we view space. Launched on April 24, 1990, the telescope continues its mission today. To celebrate its anniversary, NASA released four recent images taken by Hubble that prove its staying power even after three decades !

We are back from Portugal, a little jet-lagged (always milder going east to west than vice-versa) and none the worse for the wear. Time to upload the 1,136 images that I took. Here's a garden abstract from the archives while I get to it. :)
- Rosa's Garden of Earthly Delights, Keefer Lake, Ontario, Canada -
Dans la constellation du Poisson Volant (Volans) à 300 millions d'a.l. de la Terre, l'anneau de Lindsay-Shapley AM 0644-741 est une galaxie lenticulaire non barrée et en anneau. Elle avait autrefois un noyau jaunâtre qui était le centre d’une galaxie spirale normale. Il se serait formé par une collision avec une autre galaxie, ce qui a déclenché un effet gravitationnel et une perturbation provoquant la condensation de la poussière, ce qui l'a forcé à s'étendre et à créer un anneau. D'une taille de 150 000 a.l., il possède aujourd'hui une région de formation d'étoiles dominée par de jeunes étoiles massives, bleues et chaudes. Les régions roses le long de l'anneau sont des nuages raréfiés d'hydrogène gazeux rougeoyant et fluorescent, alors qu'il est bombardé par une forte lumière ultraviolette émise par les étoiles bleues. Il continuera à s’étendre pendant encore 300 millions d’années, après quoi il commencera à se désintégrer.
Outre les deux grandes structures galactiques proches, plusieurs galaxies très éloignées sont visibles sur l'image, principalement dans sa partie inférieure gauche. Les deux stries rougeâtres et les autres petites structures elliptiques témoignent que leur lumière a été émise bien avant celle des galaxies voisines et qu'elles sont donc bien plus éloignées de nous dans l’espace-temps (cf. site Hubble).

A black hole forms in a giant cumulus cloud where nothing can escape, well not actually nothing but it’s toil and trouble for somebody, that ship on the horizon for instance.
A 130 millions d'a.l., les bras gracieux et sinueux de la majestueuse galaxie spirale NGC 3147, d'un diamètre de 83 000 a.l., apparaissent comme un grand escalier en spirale balayant l’espace dans cette image du télescope spatial Hubble. Ce sont en fait de longues bandes de jeunes étoiles bleues, de nébuleuses roses et de poussière. La beauté de la galaxie dément le fait qu’en son centre même se trouve un trou noir mal nourri, entouré d’un disque mince et compact d’étoiles, de gaz et de poussière qui ont été pris dans un maelstrom gravitationnel. La gravité du trou noir est si intense que tout ce qui s’aventure près de lui est balayé dans le disque. Ce dernier est si profondément ancré dans le champ gravitationnel intense du trou noir que la lumière du disque de gaz est modifiée, selon les théories de relativité d’Einstein, donnant aux astronomes un aperçu unique des processus dynamiques proches (cf. hubblesite.org).

Clustered at the center of this image are six brilliant spots of light, four of them creating a circle around a central pair. Appearances can be deceiving, however, as this formation is not composed of six individual galaxies, but is actually two separate galaxies and one distant quasar imaged four times. Data from the NASA/ESA Hubble Space Telescope also indicates that there is a seventh spot of light in the very center, which is a rare fifth image of the distant quasar. This rare phenomenon is the result of the two central galaxies, which are in the foreground, acting as a lens.
The four bright points around the galaxy pair, and the fainter one in the very center, are in fact five separate images of a single quasar (known as 2M1310-1714), an extremely luminous but distant object. The reason we see this quintuple effect is a phenomenon called gravitational lensing. Gravitational lensing occurs when a celestial object with an enormous amount of mass – such as a pair of galaxies – causes the fabric of space to warp. When light from a distant object travels through that gravitationally warped space, it is magnified and bent around the huge mass. This allows humans here on Earth to observe multiple, magnified images of the far-away source. The quasar in this image actually lies farther away from Earth than the pair of galaxies. The galaxy pair’s enormous mass bent and magnified the light from the distant quasar, giving the incredible appearance that the galaxies are surrounded by four quasars – when in reality, a single quasar lies far beyond them!
Hubble’s Wide Field Camera 3 (WFC3) imaged the trio in spectacular detail. It was installed on Hubble in 2009 during Hubble Servicing Mission 4, Hubble’s final servicing mission. WFC3 continues to provide both top-quality data and fantastic images 12 years after its installation.

Pretty chilly here today so back to indoor flowers for the moment!
Spanning from 2003 to 2021, this collection of images from the NASA/ESA Hubble Space Telescope features galaxies that are all hosts to both Cepheid variables and supernovae. These two celestial phenomena are both crucial tools used by astronomers to determine astronomical distance, and have been used to refine our measurement of Hubble’s constant, the expansion rate of the Universe.

This image from the NASA/ESA Hubble Space Telescope shows two of the galaxies in the galactic triplet Arp 248 — also known as Wild's Triplet — which lies around 200 million light-years from Earth in the constellation Virgo. The two large spiral galaxies visible in this image — which flank a smaller, unrelated background spiral galaxy — seem to be connected by a luminous bridge. This elongated stream of stars and interstellar dust is known as a tidal tail, and it was formed by the mutual gravitational attraction of the two foreground galaxies.
This observation comes from a project which delves into two rogues’ galleries of weird and wonderful galaxies: A Catalogue Of Southern Peculiar Galaxies And Associations, compiled by astronomers Halton Arp and Barry Madore, and the Atlas of Peculiar Galaxies, compiled by Halton Arp. Each collection contains a menagerie of spectacularly peculiar galaxies, including interacting galaxies such as Arp 248, as well as one- or three-armed spiral galaxies, galaxies with shell-like structures, and a variety of other space oddities.
Hubble used its Advanced Camera for Surveys to scour this menagerie of eccentric galaxies in search of promising candidates for future observations with the NASA/ESA/CSA James Webb Space Telescope, the Atacama Large Millimeter/submillimeter Array, and Hubble itself. With such a wealth of astronomical objects to study in the night sky, projects such as this, which guide future observations, are a valuable investment of observing time. As well as the scientific merits of observing these weird and wonderful galaxies, they were also — very unusually — selected as Hubble targets because of their visual appeal to the general public!

La nébuleuse planétaire NGC 2899 est située à 4 500 années-lumière de la Terre et à 25 895 années-lumière du centre galactique dans la constellation australe des Voiles (Vela). Cet objet présente un flux de gaz cylindrique, bipolaire et diagonal propulsé par le rayonnement et les vents stellaires d'une naine blanche située en son centre. En réalité, deux étoiles compagnes pourraient interagir et sculpter la nébuleuse, pincée en son centre par un anneau fragmenté (tore) qui ressemble à un beignet à moitié mangé. Elle présente une forêt de "piliers" gazeux pointant vers la source du rayonnement et des vents stellaires. Ses couleurs proviennent de l'hydrogène et de l'oxygène brillants (cf. NASA, ESA, STScI ; Image Processing : Joseph DePasquale STScI).

Astronomers using NASA’s Hubble Space Telescope have discovered an immense cloud of hydrogen dubbed “The Behemoth” bleeding from a planet orbiting a nearby star. The enormous, comet-like feature is about 50 times the size of the parent star. The hydrogen is evaporating from a warm, Neptune-sized planet, due to extreme radiation from the star.
This phenomenon has never been seen around an exoplanet so small. It may offer clues to how other planets with hydrogen-enveloped atmospheres could have their outer layers evaporated by their parent star, leaving behind solid, rocky cores. Hot, rocky planets such as these that roughly the size of Earth are known as Hot-Super Earths.
“This cloud is very spectacular, though the evaporation rate does not threaten the planet right now,” explains the study’s leader, David Ehrenreich of the Observatory of the University of Geneva in Switzerland. “But we know that in the past, the star, which is a faint red dwarf, was more active. This means that the planet evaporated faster during its first billion years of existence because of the strong radiation from the young star. Overall, we estimate that it may have lost up to 10 percent of its atmosphere over the past several billion years.”

Caption: This artist's concept shows "The Behemoth," an enormous comet-like cloud of hydrogen bleeding off of a warm, Neptune-sized planet just 30 light-years from Earth. Also depicted is the parent star, which is a faint red dwarf named GJ 436. The hydrogen is evaporating from the planet due to extreme radiation from the star. A phenomenon this large has never before been seen around any exoplanet.

Astronomers found something they weren't expecting at the heart of the globular cluster NGC 6397: a concentration of smaller black holes lurking there instead of one massive black hole.
Globular clusters are extremely dense stellar systems, which host stars that are closely packed together. These systems are also typically very old — the globular cluster at the focus of this study, NGC 6397, is almost as old as the universe itself. This cluster resides 7,800 light-years away, making it one of the closest globular clusters to Earth. Due to its very dense nucleus, it is known as a core-collapsed cluster.
At first, astronomers thought the globular cluster hosted an intermediate-mass black hole. These are the long-sought "missing link" between supermassive black holes (many millions of times our Sun's mass) that lie at the cores of galaxies, and stellar-mass black holes (a few times our Sun's mass) that form following the collapse of a single massive star. Their mere existence is hotly debated. Only a few candidates have been identified to date.

The Prawn Nebula is located in the Sagittarius Arm of the Milky Way, in the constellation Scorpius. Other names include both IC 4628, and Gum 56. From our vantage point, it is about 6,000 light-years away. IC 4628 is an extensive stellar nursery containing a large number of very hot, luminous, young stars created from the surrounding gases.
The nebula is about 250 light-years in diameter, with an apparent size of 1.5 degrees. For reference, this would cover an area three to four times the size of the moon. With my instrument, the full moon will fill my sensor. Unfortunately, I can’t fit the entire complex within this image.
Gum 56 is very faint and emits light at wavelengths not visible to our eyes. Two luminous giants and several young stars in this nebula emit an incredible amount of ultraviolet radiation ionising the hydrogen gas. The result, it glows. Within this invisibility, many things are concealed. Material ejected from violent supernova in the past provides new materials that allow for the formation of new stars. The cycle of stellar life and death continues as dust and gases collapse down, forming new stars.
The photo presented is a narrowband image created by combining filtered light from SII, Ha, and OIII filters. It allows us to reveal details of objects that we cannot see easily, or not at all. Often, the results can be very striking and dramatic. I tried to retain that pleasing gradient of yellow golds, through bands of teal, and hues of blue found in a traditional Hubble Palette image. I was pleased with the star colours ranging from blue to red, using only the narrowband filters. These colours appear very different from a traditional true colour image constructed with red, green, blue filtered light.

This image shows the winding green filaments observed by the NASA/ESA Hubble Space Telescope within eight different galaxies. The ethereal wisps in these images were illuminated, perhaps briefly, by a blast of radiation from a quasar – a very luminous and compact region that surrounds a supermassive black hole at the centre of a galaxy.
In each of these eight images a quasar beam has caused once-invisible filaments in deep space to glow through a process called photoionisation. Oxygen, helium, nitrogen, sulphur and neon in the filaments absorb light from the quasar and slowly re-emit it over many thousands of years.
Their unmistakable emerald hue is caused by ionised oxygen, which glows green.
The Hubble team found a total of twenty galaxies that had gas ionised by quasars; those featured here are (from left to right on top row) the Teacup (more formally known as 2MASX J14302986+1339117), NGC 5972, 2MASX J15100402+0740370 and UGC 7342, and (from left to right on bottom row) NGC 5252, Mrk 1498, UGC 11185 and 2MASX J22014163+1151237.

Here is Melotte 15 inside of the Heart Nebula in SHO (SII, Ha, OIII)
The jellyfish galaxy JW39 hangs serenely in this image from the NASA/ESA Hubble Space Telescope. This galaxy lies over 900 million light-years away in the constellation Coma Berenices, and is one of several jellyfish galaxies that Hubble has been studying over the past two years.
Despite this jellyfish galaxy’s serene appearance, it is adrift in a ferociously hostile environment; a galaxy cluster. Compared to their more isolated counterparts, the galaxies in galaxy clusters are often distorted by the gravitational pull of larger neighbours, which can twist galaxies into a variety of weird and wonderful shapes. If that was not enough, the space between galaxies in a cluster is also pervaded with a searingly hot plasma known as the intracluster medium. While this plasma is extremely tenuous, galaxies moving through it experience it almost like swimmers fighting against a current, and this interaction can strip galaxies of their star-forming gas.
This interaction between the intracluster medium and the galaxies is called ram-pressure stripping, and is the process responsible for the trailing tendrils of this jellyfish galaxy. As JW39 has moved through the cluster the pressure of the intracluster medium has stripped away gas and dust into long trailing ribbons of star formation that now stretch away from the disc of the galaxy.
Astronomers using Hubble’s Wide Field Camera 3 studied these trailing tendrils in detail, as they are a particularly extreme environment for star formation. Surprisingly, they found that star formation in the ‘tentacles’ of jellyfish galaxies was not noticeably different from star formation in the galaxy disc.
[Image Description: A spiral galaxy. It is large in the centre with a lot of detail visible. The core glows brightly and is surrounded by concentric rings of dark and light dust. The spiral arms are thick and puffy with grey dust and glowing blue areas of star formation. They wrap around the galaxy to form a ring. Part of the arm is drawn out into a dark thread above the galaxy, and dust from the arm trails off to the right.]

'Tis the season for holiday decorating and tree-trimming. Not to be left out, astronomers using NASA's Hubble Space Telescope have photographed a festive-looking nearby planetary nebula called NGC 5189. The intricate structure of this bright gaseous nebula resembles a glass-blown holiday ornament with a glowing ribbon entwined.
Planetary nebulae represent the final brief stage in the life of a medium-sized star like our sun. While consuming the last of the fuel in its core, the dying star expels a large portion of its outer envelope. This material then becomes heated by the radiation from the stellar remnant and radiates, producing glowing clouds of gas that can show complex structures, as the ejection of mass from the star is uneven in both time and direction.

The sharp eye of the NASA/ESA Hubble Space Telescope captured the tiny moon Phobos during its orbital trek around Mars on 12 May 2016. The observations were intended to photograph Mars while it was on its closest approach to Earth along its orbit, so the moon’s cameo appearance was a bonus.
Over the course of 22 minutes, Hubble took 13 separate exposures, allowing astronomers to create a timelapse video showing the movement of Phobos around its host planet. Because the moon is so small, just 27×22×18 km, it appears star-like in the images.
It also orbits incredibly close to Mars, just 6000 km above the planet, making it closer to its parent planet than any other moon in the Solar System.
Sibling Deimos orbits much further out, at a distance of some 23 500 km.
While the origin of the moons is much debated, their fate is inevitable. Phobos is gradually spiraling in towards Mars and within 50 million years will likely either break up due to the planet’s gravity, or crash into its surface. Meanwhile, the opposite is true for Deimos: its orbit is slowly taking it away from Mars.

This image of an archetypal spiral galaxy was captured by the NASA/ESA Hubble Space Telescope.
The subject of this image is known as NGC 691, and it can be found some 120 million light-years from Earth. This galaxy was one of thousands of objects discovered by astronomer William Herschel during his prolific decades-long career spent hunting for, characterising, and cataloguing a wide array of the galaxies and nebulae visible throughout the night sky — almost 200 years before Hubble was even launched.
The intricate detail visible in this Picture of the Week would likely be extraordinary to Herschel. Hubble was able to capture an impressive level of structure within NGC 691’s layers of stars and spiralling arms — all courtesy of the telescope’s high-resolution Wide Field Camera 3.

Another wet and windy day so yet another indoor shot. Oil and water with some wrapping paper underneath. It's not perfect, but I liked the shapes and colours in this one.
