La galaxie IC 342 (Hubble) est située 11 millions d'années-lumière de la Terre dans la constellation de la Girafe (Camelopardalis). Elle est également connue sous les noms d'UGC 2847, LEDA 13826 et Caldwell 5, mesure environ 50 000 années-lumière de diamètre et est vieille de plusieurs milliards d'années. Bien brillante, elle se situe près de l'équateur du disque de la Voie lactée, là où le ciel est dense de gaz cosmique incandescent, d'étoiles brillantes et de poussière sombre et obscurcissante. Sa structure spirale complexe s'observant à travers une grande quantité de matière contenue dans la Voie lactée est relativement difficile à repérer, d'où son surnom intriguant de "Galaxie caxhée".
Sa vue frontale et scintillante montre au centre des vrilles de poussière entrelacées formant des bras spectaculaires qui entourent un noyau brillant de gaz chaud et d'étoiles. Ce noyau est appelé noyau H II, zone d'hydrogène atomique devenue ionisée et constitué de "berceaux énergétiques" de milliers d'étoiles se formant en quelques millions d'années. Chaque jeune étoile bleue, extrêmement chaude, émet de la lumière ultraviolette, ionisant davantage l'hydrogène environnant (cf. NASA / ESA / Hubble / P. Sell, University of Florida / P. Kaaret, University of Iowa / G. Kober, NASA’s Goddard Space Flight Center / Catholic University of America).

This Hubble Picture of the Week shows the jewel-bright spiral galaxy NGC 4689, which lies 54 million light-years from Earth in the constellation Coma Berenices. This constellation has the distinction of being the only one of the 88 constellations officially recognised by the International Astronomical Union (IAU) to be named after an historical figure, Queen Berenice II of Egypt. The latin word ‘coma’ references her hair, meaning that NGC 4689 can be said to be found in the hair of a queen. Some people of Berenice’s time would have meant this quite literally, as the story goes that her court astronomer thought that a missing lock of Berenice’s hair had been catasterised (a word meaning ‘placed amongst the stars’) by the gods: hence the name of the constellation, Coma Berenices.
NGC 4689 holds an interesting — albeit less royal — place in modern astronomy too. The Universe is so incredibly vast that at a distance of a mere 54 million light-years NGC 4689 is relatively nearby for a galaxy. This image has been made using data from two sets of observations, one made in 2019 and 2024, both of which were made as a part of programmes that observed multiple ‘nearby’ galaxies. The 2024 observing programme is an interesting example of how Hubble — a relatively old but extraordinarily productive telescope — can support the work of the technologically cutting-edge Webb telescope. Observations collected by Webb stand to transform our understanding of how galaxies transform and evolve over time, by providing data of an unprecedented level of detail and clarity. However, thanks to their complementary capabilities, new observations from Hubble — such as those used to create this image — can assist the work done using Webb. In this case, the Hubble data were collected in order to get a more accurate grasp of the stellar populations of nearby galaxies, which is crucial to understanding the evolution of galaxies. Thus, NGC 4689 is playing an important role in developing our understanding of how all galaxies evolve. In fact, it is observed enough that it has been the subject of a Hubble Picture of the Week before, in 2020.
[Image Description: A spiral galaxy is viewed close up and fills most of the scene. It has a bright, glowing spot at the core, broad spiral arms that are covered by many dark threads of dust, and pink glowing spots across the disc that mark areas of star formation. The disc of the galaxy is surrounded by a faint halo that bleeds into the dark background.]

This was data I captured last year and only processed in Ha & Oiii as could not get a decent hubble palette image that I was happy with.
This time I managed to get something I was happy with, maybe all the hours spent on photoshop starting to pay off.
Rather than a dark point travelling across a star, I thought an artistic interpretation would be far more interesting! The Hubble telescope is a fascinating development in Space technology, but speculation is key to astronomers interpretations. The concept of a large, Jupiter-like planet and the fine line between large, gaseous planets and stars was key to this composition. Here, instead of Saturn-like rings, matter orbits the planet in a far more arbitrary fashion. I've also depicted a planetary binary-system, where the planet at the rear of the picture is more star-like than the planet at the front. Both planets are emitting large amounts of energy and this causes orbiting matter to collect into "patterns" that reflect the magnetic fields of the planets.

Bright, frosty polar caps, and clouds above a vivid, rust-colored landscape reveal Mars as a dynamic seasonal planet in this NASA Hubble Space Telescope view taken on May 12, 2016, when Mars was 50 million miles from Earth. The Hubble image reveals details as small as 20 to 30 miles across.
The large, dark region at far right is Syrtis Major Planitia, one of the first features identified on the surface of the planet by seventeenth-century observers. Christiaan Huygens used this feature to measure the rotation rate of Mars. (A Martian day is about 24 hours and 37 minutes.) Today we know that Syrtis Major is an ancient, inactive shield volcano. Late-afternoon clouds surround its summit in this view.
A large oval feature to the south of Syrtis Major is the bright Hellas Planitia basin. About 1,100 miles across and nearly five miles deep, it was formed about 3.5 billion years ago by an asteroid impact.
The orange area in the center of the image is Arabia Terra, a vast upland region in northern Mars that covers about 2,800 miles. The landscape is densely cratered and heavily eroded, indicating that it could be among the oldest terrains on the planet. Dried river canyons (too small to be seen here) wind through the region and empty into the large northern lowlands.

Dans la constellation de la Dorade (Dorado), à 65 millions d'a.l. de la Terre, la galaxie spirale barrée NGC 1672 renferme en son centre une barre dont la brillance de surface est élevée. Quatre bras spiraux partent de ses extrémités vers l'extérieur et sont asymétriques. Le bras de la région nord-est est significativement plus brillant que celui de son opposé, avec une longueur de barre centrale faisant 65 000 a.l.. Des lignes de champ magnétique font un angle prononcé par rapport à la barre et sont tournées vers le centre de la galaxie (cf. wikipédia, merci Domingo Pestana et Raul Villaverde pour la photo).

NASA image release August 10, 2010
A long-exposure Hubble Space Telescope image shows a majestic face-on spiral galaxy located deep within the Coma Cluster of galaxies, which lies 320 million light-years away in the northern constellation Coma Berenices.
The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its center. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. Hubble has also captured the outer spiral arms of NGC 4911, along with thousands of other galaxies of varying sizes. The high resolution of Hubble's cameras, paired with considerably long exposures, made it possible to observe these faint details.
NGC 4911 and other spirals near the center of the cluster are being transformed by the gravitational tug of their neighbors. In the case of NGC 4911, wispy arcs of the galaxy's outer spiral arms are being pulled and distorted by forces from a companion galaxy (NGC 4911A), to the upper right. The resultant stripped material will eventually be dispersed throughout the core of the Coma Cluster, where it will fuel the intergalactic populations of stars and star clusters.
The Coma Cluster is home to almost 1,000 galaxies, making it one of the densest collections of galaxies in the nearby universe. It continues to transform galaxies at the present epoch, due to the interactions of close-proximity galaxy systems within the dense cluster. Vigorous star formation is triggered in such collisions.
Galaxies in this cluster are so densely packed that they undergo frequent interactions and collisions. When galaxies of nearly equal masses merge, they form elliptical galaxies. Merging is more likely to occur in the center of the cluster where the density of galaxies is higher, giving rise to more elliptical galaxies.
This natural-color Hubble image, which combines data obtained in 2006, 2007, and 2009 from the Wide Field Planetary Camera 2 and the Advanced Camera for Surveys, required 28 hours of exposure time.
The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center manages the telescope. The Space Telescope Science Institute (STScI) conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy, Inc. in Washington, D.C.

James Webb and Hubble Space Telescopes as LEGO designs by my boy from February 2016 [he was 8 years old] after seeing a documentary about Hubble.
I've waited for JWST to be launched to post this but it looks now that the launch will no happen until March 2021, so here it is.

Last week researchers from around the world gathered at the Accademia dei Lincei in Rome for the Science with the Hubble Space Telescope IV conference. The event celebrated the history of Hubble’s extraordinary achievements, and looked to the future at what might yet be achieved and how the James Webb Space Telescope will build on our knowledge of the Universe. As part of this celebration artist Tim Otto Roth revealed a new artwork, Heaven’s Carousel, inspired by Hubble’s work on the accelerating expansion of the Universe.
This image shows audiences taking in the new astronomy-inspired art installation premiered in Rome at the Science with the Hubble Space Telescope IV conference. The installation, named Heaven’s Carousel, links together the fields of art, music and astronomy. Conceptualised and designed by German artist and composer Tim Otto Roth, the work is inspired by novel work on the accelerating expansion of the Universe by Nobel laureate Adam Riess (STScl), Greek cosmology and Renaissance astronomers.

Cluster of galaxies showing gravitational lensing effects. Close to the center of this image is 2MASX J11422472+5832048, the brightest galaxy in a cluster (BCG). This galaxy is about 4.4 billion light years from us.
The massive galaxy cluster Abell 1351 is captured in this image by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 and Advanced Camera for Surveys. This galaxy cluster lies in the constellation Ursa Major in the northern hemisphere.
This image is filled with streaks of light, which are actually the images of distant galaxies. The streaks are the result of gravitational lensing, an astrophysical phenomenon that occurs when a massive celestial body such as a galaxy cluster distorts spacetime sufficiently strongly to affect the path of light passing through it — almost as if the light were passing through a gigantic lens. Gravitational lensing comes in two varieties — strong and weak — and both can give astronomers an insight into the distribution of mass within a lensing galaxy cluster such as Abell 1351.
This observation is part of an astronomical album comprising snapshots of some of the most massive galaxy clusters. This menagerie of massive clusters demonstrates interesting astrophysical phenomena such as strong gravitational lensing, as well as showcasing spectacular examples of violent galaxy evolution. To obtain this astronomical album, astronomers proposed a Snapshot Program to be slotted into Hubble’s packed observing schedule. These Snapshot Programs are lists of separate, relatively short exposures which can fit into gaps between longer Hubble observations. Having a large pool of Snapshot candidates to dip into allows Hubble to use every second of observing time possible and to maximise the scientific output of the observatory.

The Pinwheel Galaxy - Messier 101
M101 is a large face-on spiral galaxy located 22 million light-years away in the constellation of Ursa Major. At magnitude +7.9, it can be glimpsed in binoculars or small telescopes from dark sites but suffers from low surface brightness and in bad seeing conditions or light polluted areas, the galaxy can be difficult to spot. It's best seen from the Northern Hemisphere during the months of March, April and May.
M101 is also known as "The Pinwheel Galaxy" and was discovered by Pierre Méchain on March 27, 1781. He described it as "nebula without star, very obscure and pretty large, 6' to 7' in diameter, between the left hand of Bootes and the tail of the great Bear." He communicated this to Charles Messier who verified its position and then included it in his catalogue as one of the final entries.

A star's spectacular death in the constellation Taurus was observed on Earth as the supernova of 1054 A.D. Now, almost a thousand years later, a superdense neutron star left behind by the stellar death is spewing out a blizzard of extremely high-energy particles into the expanding debris field known as the Crab Nebula.
This composite image uses data from three of NASA's Great Observatories. The Chandra X-ray image is shown in light blue, the Hubble Space Telescope optical images are in green and dark blue, and the Spitzer Space Telescope's infrared image is in red. The size of the X-ray image is smaller than the others because ultrahigh-energy X-ray emitting electrons radiate away their energy more quickly than the lower-energy electrons emitting optical and infrared light. The neutron star, which has the mass equivalent to the sun crammed into a rapidly spinning ball of neutrons twelve miles across, is the bright white dot in the center of the image.

Niagara Falls.
I don’t take a lot of landscapes really so finding images for the 7 Days With Flickr group’s Saturday Landscapes theme generally sees me sorting through my back catalogue in some desperation.
This is a 180-degree panorama of Niagara Falls that I took last September from the Canadian side. The Horseshoe Falls are on the right - an impressive witch’s cauldron of rising spray - and the American falls are further down in the mid left. The bridge in the distance on the left forms the border with the US of A.
The trouble with seeing a place in real life which is so familiar from the media is that it tends to disappoint. And so with Niagara to some extent. But what does impress is the sheer power of the volume of water that flows over the edge which no film can really convey. It’s quite scary and rightly so.
Another image where nature wins :)
Thanks for taking time to look. I hope you enjoy the image :) Happy 7DWF!
There were all sorts of problems with this in-camera jpeg - colour and exposure gradients for example. I tweaked it in Affinity Photo as best I could, but it was a case of "I wouldn't start from there if I were you." :)
Festive Nebulas Light Up Milky Way Galaxy Satellite
Two glowing nebulas in the Small Magellanic Cloud, a dwarf galaxy that is a satellite of our Milky Way galaxy, have been observed by NASA's Hubble Space Telescope. Young, brilliant stars at the center of each nebula are heating hydrogen, causing these clouds of gas and dust to glow red. The image is part of a study called Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE). Astronomers are using Hubble to probe the Milky Way satellite to understand how dust is different in galaxies that have a far lower supply of heavy elements needed to create dust.

February 24, 1987, will be remembered as one of the most spectacular events observed by astronomers in modern times. The destruction of a massive star in the Large Magellanic Cloud, a nearby galaxy, resulted in Supernova 1987A. This spawned detailed observations by many different telescopes, including NASA's Chandra X-ray Observatory and Hubble Space Telescope. The outburst was visible to the naked eye, and has been the brightest known supernova in almost 400 years.
This composite image from February 22, 2007, - 20 years after the supernova - shows the effects of a powerful shock wave moving away from the explosion. Bright spots of X-ray and optical emission arise where the shock collides with structures in the surrounding gas. These structures were carved out by the wind from the destroyed star. Hot-spots in the Hubble image (pink-white) now encircle Supernova 1987A like a necklace of incandescent diamonds. The Chandra data (blue-purple) reveals multimillion-degree gas at the location of the optical hot-spots. These data give valuable insight into the behavior of the doomed star in the years before it exploded.

This is a Hubble Space Telescope image of the farthest spectroscopically confirmed galaxy observed to date (inset). It was identified in this Hubble image of a field of galaxies in the CANDELS survey (Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey). NASA’s Spitzer Space Telescope also observed the unique galaxy. The W. M. Keck Observatory was used to obtain a spectroscopic redshift (z=7.7), extending the previous redshift record. Measurements of the stretching of light, or redshift, give the most reliable distances to other galaxies. This source is thus currently the most distant confirmed galaxy known, and it appears to also be one of the brightest and most massive sources at that time. The galaxy existed over 13 billion years ago. The near-infrared light image of the galaxy (inset) has been colored blue as suggestive of its young, and hence very blue, stars. The CANDELS field is a combination of visible-light and near-infrared exposures.

This close-up Hubble view of the Meathook Galaxy (NGC 2442) focuses on the more compact of its two asymmetric spiral arms as well as the central regions. The spiral arm was the location of a supernova that exploded in 1999. These Hubble observations were made in 2006 in order to study the aftermath of this supernova. Ground-based data from MPG/ESO 2.2-metre telescope were used to fill out parts of the edges of this image.
Another one from the Hubble legacy archives processed in PixInsight & Photoshop. Unfortunately, there were some gradients and this is the best I could do under the circumstances.

Description:
The LMC is a satellite galaxy of our own Milky Way that is part of the Local Group of galaxies, lies about 163,000 light years from us, and has a diameter of about 14,000 light years (compared with our Milky Way’s diameter of ~106,000 light years). Nearby is the smaller galaxy called the Small Magellanic Cloud (SMC).
To the unaided eye in a dark sky site the LMC is a large, faint glowing patch that appears detached from the band of the Milky Way.
From Wikipedia:
"Although both clouds have been easily visible for southern nighttime observers well back into prehistory, the first known written mention of the Large Magellanic Cloud was by the Persian astronomer `Abd al-Rahman al-Sufi Shirazi, (later known in Europe as "Azophi"), in his Book of Fixed Stars around 964 AD.
The next recorded observation was in 1503–4 by Amerigo Vespucci in a letter about his third voyage. In this letter he mentions "three Canopes [sic], two bright and one obscure"; "bright" refers to the two Magellanic Clouds, and "obscure" refers to the Coalsack.
Ferdinand Magellan sighted the LMC on his voyage in 1519, and his writings brought the LMC into common Western knowledge. The galaxy now bears his name.
Measurements with the Hubble Space Telescope, announced in 2006, suggest the Large and Small Magellanic Clouds may be moving too fast to be orbiting the Milky Way."
The Tarantula Nebula (upper left in this view) is a region of glowing hydrogen gas within the LMC. It is extremely luminous, so much so that if it were at the distance of the Orion Nebula it would cast shadows.

Astronomers using NASA's Hubble Space Telescope have found compelling evidence of a planet forming 7.5 billion miles away from its star, a finding that may challenge current theories about planet formation.
Of the almost 900 planets outside our solar system that have been confirmed to date, this is the first to be found at such a great distance from its star. The suspected planet is orbiting the diminutive red dwarf TW Hydrae, a popular astronomy target located 176 light-years away from Earth in the constellation Hydra the Sea Serpent.

Hubble Serves Up a Holiday Snow Angel
Hubble Space Telescope's high resolution combines with the Subaru Telescope's wide field-of-view to reveal a depiction of star-forming region S106 that is not possible from either telescope alone. The bipolar S106 shows bright gas in two distinct lobes. The faint stars located near the nebulosity are brown dwarf candidates associated with the region of star formation.
This composite image combines optical and near-infrared astronomical data from the Hubble Space Telescope with mid-infrared data from the ground-based Subaru Telescope, located on Mauna Kea in Hawaii. The Hubble data (H-alpha, J, and H) were taken as part of Hubble Heritage observations of S106 in Feburary 2011. The Subaru data (J, H, and K) were obtained in May 1999.

In shadowy space, in the loneliness of the final frontier, well out of Hubble’s reach both sweet and savoury comestibles spin around their own axis. Are these, in the interstellar emptiness spinning tops, which seem to float in-between dimension and space, snacks of the Starchild, canteen waste of the Imperial fleet or was the teleport perhaps acting up agin? All possibilities are infinitely improbable, ou quoi Valérian?

Data: Hubble Space Telescope / Hubble Legacy Archive
From NASA: “NGC 5793 is a spiral galaxy over 150 million light-years away in the constellation of Libra. This galaxy has two particularly striking features: a beautiful dust lane and an intensely bright center — much brighter than that of our own galaxy, or indeed those of most spiral galaxies we observe.
NGC 5793 is a Seyfert galaxy. These galaxies have incredibly luminous centers that are thought to be caused by hungry supermassive black holes — black holes that can be billions of times the size of the sun — that pull in and devour gas and dust from their surroundings.”
Processing, I downloaded set of channels used for color (475nm and 775nm) from Hubble Legacy Archive. I also created an artifical Green channel for possibility of RGB combination. Standard Pixinsight workflow bring me to this final image, with a lots of cosmetic corrections that was present on the RAW files.
My goal was to create very deep-sky looking image with dark background and just galaxy in it.

The "Necklace Nebula" is located 15,000 light-years away in the constellation Sagitta (the Arrow). In this composite image, taken on July 2, 2011, Hubble's Wide Field Camera 3 captured the glow of hydrogen (blue), oxygen (green), and nitrogen (red).
The object, aptly named the Necklace Nebula, is a recently discovered planetary nebula, the glowing remains of an ordinary, Sun-like star. The nebula consists of a bright ring, measuring 12 trillion miles wide, dotted with dense, bright knots of gas that resemble diamonds in a necklace.

The Hubble Space Telescope (HST) floats gracefully above the blue Earth in December 1999 at the conclusion of HST servicing mission 3A. Hubble's release moments earlier by the Space Shuttle Discovery’s robotic arm marked the fourth time that a space shuttle had set the great observatory into space. Those occasions were the telescope's initial release in 1990 and three subsequent servicing missions including this one, shuttle mission STS-103.

Dans la constellation de la Grande ourse (Ursa Major), à 46 millions d'a.l. de la Terre, la galaxie spirale NGC 2841 présente une structure en anneau interne d'un diamètre de 150 000 a.l.. Il s’agit d’une galaxie spirale floconnante prototypique, dont les bras sont fragmentés et discontinus (cf. wikipédia, site Hubble).

The giant planet Jupiter, in all its banded glory, is revisited by the NASA/ESA Hubble Space Telescope in these latest images, taken on 5 January 2024, that capture both sides of the planet. Hubble monitors Jupiter and the other outer Solar System planets every year under the Outer Planet Atmospheres Legacy programme (OPAL). This is because these large worlds are shrouded in clouds and hazes stirred up by violent winds, leading to a kaleidoscope of ever-changing weather patterns.
Big enough to swallow Earth, the classic Great Red Spot stands out prominently in Jupiter's atmosphere. To its lower right, at a more southerly latitude, is a feature sometimes dubbed Red Spot Jr. This anticyclone was the result of storms merging in 1998 and 2000, and it first appeared red in 2006 before returning to a pale beige in subsequent years. This year it is somewhat redder again. The source of the red coloration is unknown but may involve a range of chemical compounds: sulphur, phosphorus or organic material. Staying in their lanes, but moving in opposite directions, Red Spot Jr. passes the Great Red Spot about every two years. Another small red anticyclone appears in the far north.
[Image description: Jupiter is banded with stripes of brownish orange, light grey, soft yellow, and shades of cream, punctuated with many large storms and small white clouds. The largest storm, the Great Red Spot, is the most prominent feature in the left bottom third of this view. To its lower right is a smaller reddish anticyclone, Red Spot Jr.]

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 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.
