NGC 2359 (also known as Thor's Helmet) is an emission nebula in the constellation Canis Major. The nebula is approximately 11.96 thousand light years away and 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot giant thought to be in a brief pre-supernova stage of evolution. It is similar in nature to the Bubble Nebula, but interactions with a nearby large molecular cloud are thought to have contributed to the more complex shape and curved bow-shock structure of Thor's Helmet.
It is also catalogued as Sharpless 2-298 and Gum 4.
The nebula has an overall bubble shape, but with complex filamentary structures. The nebula contains several hundred solar masses of ionised material, plus several thousand more of unionised gas. It is largely interstellar material swept up by winds from the central star, although some material does appear to be enriched with the products of fusion and is likely to come directly from the star.The expansion rate of different portions of the nebula varies from 10km/s to at least 30km/s, leading to age estimates of 78,500 - 236,000 years. The nebula has been studied at radio and x-ray wavelengths, but it is still unclear whether it was produced at the class O main sequence stage of development, as a red supergiant, luminous blue variable, or mainly as a Wolf-Rayet star.

Explanation: This colorful cosmic skyscape features a peculiar system of galaxies cataloged as Arp 227 some 100 million light-years distant. Swimming within the boundaries of the constellation Pisces, Arp 227 consists of the two galaxies prominent on the left; the curious shell galaxy NGC 474 and its blue, spiral-armed neighbor NGC 470. The faint, wide arcs or shells of NGC 474 could have been formed by a gravitational encounter with neighbor NGC 470. Alternately the shells could be caused by a merger with a smaller galaxy producing an effect analogous to ripples across the surface of a pond. Remarkably, the large galaxy on the right hand side of the deep image, NGC 467, appears to be surrounded by faint shells too, evidence of another interacting galaxy system. Intriguing background galaxies are scattered around the field that also includes spiky foreground stars. Of course, those stars lie well within our own Milky Way Galaxy. The field of view spans 25 arc minutes or about 1/2 degree on the sky. (text: apod.nasa.gov/apod/ap110226.html)

NGC 4631 (also known as the Whale Galaxy or Caldwell 32) is an edge-on spiral galaxy in the constellation Canes Venatici. This galaxy's slightly distorted wedge shape gives it the appearance of a herring or a whale, hence its nickname. Because this nearby galaxy is seen edge-on from Earth, professional astronomers observe this galaxy to better understand the gas and stars located outside the plane of the galaxy.

**Prompt :**
Deux planètes massives de type tellurique entrent en collision frontale dans l’immensité du vide spatial, capturées à l’instant précis de l’impact. La scène est hyperréaliste, avec un niveau de détail extrême : croûtes planétaires fissurées laissant apparaître des veines de magma incandescent, continents fragmentés, océans vaporisés en nuages de plasma. L’explosion centrale émet une lumière blanche aveuglante entourée d’un halo orange brûlant, projetant des jets de matière en fusion dans toutes les directions.
Des fragments rocheux de tailles variées flottent et tourbillonnent dans un ballet chaotique, certains encore en combustion, d’autres déjà refroidis, texturés avec une précision géologique. Des traînées de débris incandescents dessinent des arcs dynamiques, créant une sensation de mouvement intense et de puissance colossale. Les atmosphères des deux planètes se mélangent dans une tempête de gaz ionisés, formant des volutes lumineuses et turbulentes.
L’éclairage est dramatique et contrasté : la lumière de l’impact illumine violemment les surfaces fracturées tandis que l’arrière-plan spatial reste profond, presque noir, parsemé d’étoiles lointaines. Effet de lens flare cinématographique subtil, particules fines en suspension, rendu volumétrique de la lumière et de la chaleur.
Caméra virtuelle positionnée en légère plongée, avec une perspective grand angle (24mm), profondeur de champ maîtrisée, mise au point nette sur la zone de collision, flou progressif sur les débris en périphérie. Style visuel proche d’un blockbuster spatial, mélange de réalisme scientifique et d’esthétique épique, rendu 8K, textures ultra détaillées, global illumination, ray tracing, photoréalisme extrême.
Ambiance : apocalyptique, grandiose, énergie brute, sensation de fin et de renaissance cosmique.

**Prompt:**
Two massive terrestrial planets collide head-on in the vast emptiness of space, captured at the exact moment of impact. The scene is hyperrealistic, with extreme detail: planetary crusts cracking open to reveal glowing veins of molten magma, shattered continents, and oceans instantly vaporized into clouds of plasma. At the center, a blinding white explosion radiates outward, surrounded by a blazing orange halo, ejecting streams of incandescent matter in all directions.
Fragments of rock of varying sizes drift and spiral in a chaotic ballet, some still burning, others cooling with highly detailed geological textures. Trails of fiery debris carve dynamic arcs through space, emphasizing intense motion and colossal force. The atmospheres of both planets merge into a violent storm of ionized gases, forming luminous, turbulent swirls.
Lighting is dramatic and high-contrast: the impact’s brilliance harshly illuminates fractured planetary surfaces, while the deep space background remains nearly black, scattered with distant stars. Subtle cinematic lens flare, fine suspended particles, volumetric lighting, and heat distortion effects enhance realism.
Virtual camera positioned in a slight top-down angle with a wide-angle lens (24mm), controlled depth of field, sharp focus on the collision point, gradual blur on peripheral debris. Visual style reminiscent of a high-budget space blockbuster, blending scientific realism with epic aesthetics. Rendered in 8K, ultra-detailed textures, global illumination, ray tracing, extreme photorealism.
Mood: apocalyptic, awe-inspiring, raw cosmic energy, a sense of destruction and rebirth.

Ou4 the Giant Squid Nebula, Data in from last night 1800 x 14 at F3
Ha Tonight! Looking at the individual subs there is not much to see but when they are all stacked and treated the elusive squid begins to reveal it's self.
Messier 13 (M13), also designated NGC6205 and sometimes called theGreat Globular Cluster in Hercules or the Hercules Globular Cluster, is a globular cluster of about 300,000 stars in the constellation of Hercules.
M13 is about 145 light-years in diameter and is 25,100 light-years away from Earth.
It was discovered in 1714 by Edmund Halley.
A globular cluster is a spherical collection of stars that orbits a galactic core as as satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centres.

Like three years ago, starting the new season with a wonderful and enchanting Hubble's Variable Nebula (NGC 2261)
Previous approach: www.flickr.com/photos/olegbr/8552071862/in/dateposted/
I wanted to personally check whether it still variable ...
It was found that this is so :)
Here animation L-channel 200%: olegbr.astroclub.kiev.ua/files/astrofoto/NGC2261/NGC2261_...
Of course, 3 years - a very large interval for observing the changes in the nebula. Everything is much faster: www.umanitoba.ca/science/astronomy/cbrown/imaging/hvn/ana...
In 2013-2016 animation, I drew attention to the star just above the nebula, which is for 3 years significantly shifted to the right.
To heighten the effect, combined with the current picture image DSS., For about 60 years, the offset is already pretty decent. olegbr.astroclub.kiev.ua/files/astrofoto/NGC2261/NGC2261_...
Here www.astrosurf.com/mcianci/ngc2261.html Italian colleague calculated that the proper motion (proper motion) of the star 0.2" per year. The name is NLTT 16798 and is listed as High Proper Motion Star: simbad.u-strasbg.fr/simbad/sim-id?Ident=NLTT+16798
Explanation: What causes Hubble's Variable Nebula to vary? The unusual nebula pictured above changes its appearance noticeably in just a few weeks. Discovered over 200 years ago and subsequently cataloged as NGC 2661, the remarkable nebula is named for Edwin Hubble, who studied it earlier this century. Hubble's Variable Nebula is a reflection nebula made of gas and fine dust fanning out from the star R Monocerotis. The faint nebula is about one light-year across and lies about 2500 light-years away towards the constellation of Monocerotis. A leading variability explanation for Hubble's Variable Nebula holds that dense knots of opaque dust pass close to R Mon and cast moving shadows onto the reflecting dust seen in the rest of the nebula.

### 🎬 **Prompt cinématographique hyperréaliste**
Portrait rapproché d’une jeune femme au visage délicat et naturel, peau claire parsemée de fines taches de rousseur réalistes, légèrement scintillantes comme si des particules d’or étaient incrustées sous la surface de l’épiderme. Ses yeux vert émeraude captent la lumière avec une profondeur presque liquide, reflet subtil d’un univers en expansion.
Ses cheveux blond platine, légèrement ondulés, flottent doucement comme en apesanteur, traversés par des filaments lumineux dorés évoquant des veines d’énergie cosmique. Quelques mèches sont retenues par une structure fine et élégante ressemblant à un ornement futuriste en métal doré.
L’arrière-plan est un vaste paysage spatial hyperréaliste : nébuleuses bleutées et orangées, nuages stellaires, poussières galactiques et étoiles scintillantes, avec un effet de profondeur volumétrique cinématographique. La lumière ambiante est douce mais contrastée, avec un éclairage principal chaud (golden hour cosmique) venant de la gauche et un rim light froid bleuté venant de l’arrière, créant un halo subtil autour du sujet.
Elle porte une tenue sombre, élégante et futuriste, avec des détails métalliques dorés finement gravés, rappelant une armure légère ou une combinaison d’exploratrice interstellaire. Les textures sont ultra détaillées : micro-rayures, reflets spéculaires, matériaux réalistes.
Sur sa peau apparaissent de fines lignes lumineuses dorées, comme des fractures d’énergie ou des constellations vivantes, intégrées de manière organique, diffusant une faible lueur.
Profondeur de champ très faible (f/1.4), focus ultra précis sur les yeux, bokeh cosmique en arrière-plan avec des particules lumineuses flottantes.
Rendu photographique haute définition, style hyperréaliste, 8K, détails peau réalistes, lumière cinématographique, color grading teal & gold, contraste maîtrisé, atmosphère éthérée et majestueuse.
Ambiance générale : mélange de beauté humaine et d’immensité cosmique, comme si elle incarnait une entité née des étoiles.

### 🎬 **Ultra-Detailed Cinematic Prompt (Hyperrealistic)**
Close-up portrait of a young woman with delicate, natural features, fair skin dusted with fine, realistic freckles subtly infused with shimmering golden particles, as if stardust is embedded beneath her skin. Her emerald green eyes capture light with a liquid depth, reflecting hints of a vast, expanding universe.
Her platinum blonde hair, softly wavy, flows as if suspended in zero gravity, threaded with fine golden luminous strands resembling currents of cosmic energy. A few strands are held in place by a refined, futuristic metallic hair ornament in polished gold.
The background reveals a vast, hyperrealistic cosmic landscape: swirling blue and amber nebulae, dense interstellar clouds, glowing starfields, and fine galactic dust, all rendered with cinematic volumetric depth. Lighting is soft yet dramatic, with a warm key light (cosmic golden hour) illuminating her face from the left, and a cool blue rim light from behind, creating a subtle halo around her silhouette.
She wears a dark, elegant, futuristic outfit with finely engraved golden metallic details, reminiscent of a lightweight interstellar armor or explorer suit. Textures are highly detailed: micro-scratches, realistic reflections, and physically accurate materials.
Thin glowing golden lines appear across her skin, like delicate fractures of energy or living constellations, seamlessly integrated and softly emitting light.
Extremely shallow depth of field (f/1.4), razor-sharp focus on the eyes, with a dreamy cosmic bokeh in the background filled with floating luminous particles.
Photorealistic rendering, ultra-high definition, 8K resolution, highly detailed skin texture, cinematic lighting, teal and gold color grading, controlled contrast, ethereal yet majestic atmosphere.
Overall mood: a fusion of human beauty and cosmic vastness, as if she is a being born from the stars.
