A scene from a star-forming factory shines in this NASA/ESA Hubble Space Telescope Picture of the Week. This Hubble picture captures incredible details in the dusty clouds in a star-forming region called the Tarantula Nebula. What’s possibly the most amazing aspect of this detailed image is that this nebula isn’t even in our galaxy. Instead, it’s in the Large Magellanic Cloud, a dwarf galaxy that is located about 160 000 light-years away in the constellations Dorado and Mensa.

 

The Large Magellanic Cloud is the largest of the dozens of small satellite galaxies that orbit the Milky Way. The Tarantula Nebula is the largest and brightest star-forming region not just in the Large Magellanic Cloud, but in the entire group of nearby galaxies to which the Milky Way belongs.

 

The Tarantula Nebula is home to the most massive stars known, some of which are roughly 200 times as massive as our Sun. The scene pictured here is located away from the centre of the nebula, where there is a super star cluster called R136, but very close to a rare type of star called a Wolf–Rayet star. Wolf–Rayet stars are massive stars that have lost their outer shell of hydrogen and are extremely hot and luminous, powering dense and furious stellar winds.

 

This nebula is a frequent target for Hubble, whose multiwavelength capabilities are critical for capturing sculptural details in the nebula’s dusty clouds. The data used to create this image come from an observing programme called Scylla, named for a multi-headed sea monster from the Greek myth of Ulysses. The Scylla programme was designed to complement another Hubble observing programme called ULYSSES (Ultraviolet Legacy library of Young Stars as Essential Standards). ULYSSES targets massive young stars in the Small and Large Magellanic Clouds, while Scylla investigates the structures of gas and dust that surround these stars.

 

[Image Description: A nebula. The top-left is dense with layers of fluffy pink and greenish clouds. Long strands of green clouds stretch out from here; a faint layer of translucent blue dust combines with them to create a three-dimensional scene. A sparse network of dark dust clouds in the foreground adds reddish-black patches atop the nebula. Blue-white and orange stars, from our galaxy and beyond, are spread amongst the clouds.]

The swirling, paint-like clouds in the darkness of space in this stunning image seem surreal, like a portal to another world opening before us. In fact, the subject of this NASA/ESA Hubble Space Telescope image is very real. We are seeing vast clouds of ionized atoms thrown into space by a dying star. This is a planetary nebula named Kohoutek 4-55, a member of the Milky Way galaxy situated just 4,600 light-years away in the constellation Cygnus (the Swan).

 

Planetary nebulae are the spectacular final display at the end of a giant star’s life. Once a red giant star has exhausted its available fuel and shed its last layers of gas, its compact core will contract further, enabling a final burst of nuclear fusion. The exposed core reaches extremely hot temperatures, radiating ultraviolet light that energizes the enormous clouds of gas cast off by the star. The ultraviolet light ionizes atoms in the gas, making the clouds glow brightly. In this image, red and orange indicate nitrogen, green is hydrogen, and blue shows oxygen. Kohoutek 4-55 has an uncommon, multi-layered form: a faint layer of gas surrounds a bright inner ring, all wrapped in a broad halo of ionized nitrogen. The spectacle is bittersweet, as the brief phase of fusion in the core will end after only tens of thousands of years, leaving a white dwarf that will never illuminate the clouds around it again.

Abell 39 is a planetary nebula in the constellation of Hercules. This quirky, delightful bauble is one of those deep-sky objects I’ve wanted to photograph since the moment I learned of it. Planetary nebulae are usually admired for their remarkable shapes and structures, but Abell 39 is striking to me for rather the opposite reason: it appears as an almost perfectly spherical, turquoise, soap bubble, with ripple-like shimmers of structure throughout. Amidst the negative space of a relatively featureless, dusty black backdrop of space, dotted with galaxies and stars, Abell 39 captures my imagination a delightful way. Like some sort of cosmic being’s child blew a bubble that has yet to pop.

 

I photographed Abell 39 during a few nights of camping in April and May 2024 in Skull Valley, located in Utah’s west desert, United States. Edited in PixInsight and Adobe Photoshop using 13 hours and 55 minutes of images.

Gas and dust ejected by a dying star at the heart of NGC 1514 came into complete focus thanks to mid-infrared data from NASA’s James Webb Space Telescope. Its rings, which are only detected in infrared light, now look like “fuzzy” clumps arranged in tangled patterns, and a network of clearer holes close to the central stars shows where faster material punched through.

 

This scene has been forming for at least 4,000 years — and will continue to change over many more millennia. At the center are two stars that appear as one in Webb’s observation, and are set off with brilliant diffraction spikes. The stars follow a tight, elongated nine-year orbit and are draped in an arc of dust represented in orange.

The NASA/ESA/CSA James Webb Space Telescope’s view of planetary nebula NGC 6072 in the near-infrared shows a complex scene of multiple outflows expanding out at different angles from a dying star at the centre of the scene. These outflows push gas toward the equatorial plane, forming a disc.

 

Astronomers suspect there is at least one other star interacting with the material cast off by the central dying star, creating the abnormal appearance of this planetary nebula.

 

In this image, the red areas represent cool molecular gas, for example, molecular hydrogen.

 

[Image description: colourful mostly red image of near-infrared light from a glowing cloud with a distorted, asymmetrical shape, illuminated from within by a bright central star. The asymmetrical shape resembles paint splattered on the ground. In the centre of this image, a light blue glow casts over areas of dark pockets that appear dark blue and are traced with orange material. It has a clumpy appearance. The shells become a deeper red with distance from the centre. The shells appear as lobes that push gas toward the equatorial plane, forming a disc. The background of the image is black and speckled with tiny bright stars and distant galaxies.]

For this new Picture of the Month feature, the NASA/ESA/CSA James Webb Space Telescope has provided a fantastic new view of IRAS 04302+2247, a planet-forming disc located about 525 light-years away in a dark cloud within the Taurus star-forming region. With Webb, researchers can study the properties and growth of dust grains within protoplanetary discs like this one, shedding light on the earliest stages of planet formation.

 

In stellar nurseries across the galaxy, baby stars are forming in giant clouds of cold gas. As young stars grow, the gas surrounding them collects in narrow, dusty protoplanetary discs. This sets the scene for the formation of planets, and observations of distant protoplanetary discs can help researchers understand what took place roughly 4.5 billion years ago in our own Solar System, when the Sun, Earth, and the other planets formed.

 

IRAS 04302+2247, or IRAS 04302 for short, is a beautiful example of a protostar – a young star that is still gathering mass from its environment – surrounded by a protoplanetary disc in which baby planets might be forming. Webb is able to measure the disc at 65 billion km across – several times the diameter of our Solar System. From Webb’s vantage point, IRAS 04302’s disc is oriented edge-on, so we see it as a narrow, dark line of dusty gas that blocks the light from the budding protostar at its centre. This dusty gas is fuel for planet formation, providing an environment within which young planets can bulk up and pack on mass.

 

When seen face-on, protoplanetary discs can have a variety of structures like rings, gaps and spirals. These structures can be signs of baby planets that are burrowing through the dusty disc, or they can point to phenomena unrelated to planets, like gravitational instabilities or regions where dust grains are trapped. The edge-on view of IRAS 04302’s disc shows instead the vertical structure, including how thick the dusty disk is. Dust grains migrate to the midplane of the disc, settle there and form a thin, dense layer that is conducive to planet formation; the thickness of the disc is a measure of how efficient this process has been.

 

The dense streak of dusty gas that runs vertically across this image cocoons IRAS 04302, blotting out its bright light such that Webb can more easily image the delicate structures around it. As a result, we’re treated to the sight of two gauzy nebulas on either side of the disc. These are reflection nebulas, illuminated by light from the central protostar reflecting off of the nebular material. Given the appearance of the two reflection nebulas, IRAS 04302 has been nicknamed the 'Butterfly Star'.

 

This view of IRAS 04302 features observations from Webb's Near-InfraRed Camera (NIRCam) and its Mid-InfraRed Instrument (MIRI), combined with optical data from the NASA/ESA Hubble Space Telescope. Together, these powerful facilities paint a fascinating multiwavelength portrait of a planetary birthplace. Webb reveals the distribution of tiny dust grains as well as the reflection of near-infrared light off of dusty material that extends a large distance from the disc, while Hubble focuses on the dust lane as well as clumps and streaks surrounding the dust that suggest the star is still collecting mass from its surroundings as well as shooting out jets and outflows.

 

The Webb observations of IRAS 04302 were taken as part of the Webb GO programme #2562 (PI F. Ménard, K. Stapelfeldt). This programme investigates four protoplanetary discs that are oriented edge-on from our point of view, aiming to understand how dust evolves within these discs. The growth of dust grains in protoplanetary discs is believed to be an important step toward planet formation.

I have always loved imaging planetary nebula. They are so varied in shape and form but always beautiful in their presentation. At times it’s difficult to forget that they are the result of some pretty extreme forces, good old explosions, and a bit of general stellar carnage.

 

The photo was constructed using a monochrome camera with four filters: Lum, Red, Green, and Blue. Once combined into a traditional RGB Colour image, we can see a massive range in star colours across the field. I think this is always a treat to see in astrophotography.

 

This object is located in the southern hemisphere in the constellation of Vela. In 1966, James D. Wray catalogued this wonderful PN. It is pretty small, around 2 acr min and fairly dim around magnitude 15.

The Dumbbell Nebula, M27, is a planetary nebula that lies some 1400 light years away in the constellation Vulpecula. It was the first planetary nebula discovered. Planetary nebulae consist of expanding ionized gas ejected from red giant stars. What's left is a very hot star, a white dwarf, and the UV radiation from the star ionizes the gas, providing the light we see.

The mid-infrared view of planetary nebula NGC 6072 from the NASA/ESA/CSA James Webb Space Telescope shows expanding circular shells around the outflows from the dying central star, which astronomers suspect is that pinkish white dot at the centre of the image. The longer wavelengths captured by Webb’s MIRI (Mid-Infrared Instrument) highlight the dust being cast off by the central dying star.

 

In this image, the blue represents cool molecular gas seen in red in the image from Webb’s NIRCam (Near-Infrared Camera) due to colour mapping.

A star at the centre of the image is a small point of pinkish-white light. The asymmetrical shape of the expanding cloud of gas and dust resembles paint splattered on the ground. The filaments of the expanding shells are wispy, and mostly white and blue. The shells appear as lobes that push gas toward the equatorial plane, forming a disc. A perfect circle of white-ish blue dust traces the outer edges of the shells. The background of the image is black and speckled with tiny bright stars and distant galaxies.]

NGC 40 (also known as the Bow-Tie Nebula and Caldwell 2) is a planetary nebula discovered by William Herschel on November 25, 1788, and is composed of hot gas around a dying star. The star has ejected its outer layer which has left behind a small, hot star. Radiation from the star causes the shed outer layer to heat to about 10,000 degrees Celsius and become visible as a planetary nebula. The nebula is about one light-year across. About 30,000 years from now, scientists theorize that NGC 40 will fade away, leaving only a white dwarf star approximately the size of Earth. (ref: Wikipedia)

Messier 97 is a planetary nebula in Ursa Major estimated to be about 2600 light years away.

 

The 16th magnitude central star is about 0.7 solar masses and is a remnant white dwarf having shed its outer layers about 6000 years ago based on the expansion of the nebula and then working backwards.

 

The nebula has a mass of about 0.15 solar masses.

 

Our own Sun may eventually meet a fate like this.

 

The remnant white dwarf has a surface temperature in the tens of thousands of degrees and glows brightly in UV causing fluorescence of oxygen (green-blue) and hydrogen (red) in the nebula.

The Helix Nebula is an example of a planetary nebula, formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. Gases from the star in the surrounding space appear, from our vantage point, as if we are looking down a helix structure. The remnant central stellar core, known as a planetary nebula nucleus, is destined to become a white dwarf star. The observed glow of the central star is so energetic that it causes the previously expelled gases to brightly fluoresce.

 

The Helix Nebula in the constellation of Aquarius lies about 700 light-years away, spanning about 2.5 light-years.

NASA’s Chandra X-ray Observatory contributes to the understanding of planetary nebulas by studying the hottest and most energetic processes still at work in these beautiful objects. X-ray data from Chandra reveal winds being driven away from the white dwarf so quickly (i.e., millions of miles per hour) that they create shock waves during collisions with slower-moving material previously ejected by the star. Chandra’s exceptional vision in X-rays contributes to the understanding of this brief, yet important, stage of stars’ lives. Here is the NGC 3242 planetary nebula that has been observed both by Chandra and NASA’s Hubble Space Telescope.

How I will get on as the days get even longer will be interesting. It must take a week to get any decent exposure time.

 

NGC 6765 is a small dim planetary nebula in the constellation Lyra, overshadowed by the Ring Nebula (Messier 57) which is only about 4-degrees away. The magnitude of this planetary nebula hovers around 13 and it only measures 0.67 arcmin wide. You can just start to see evidence of an outer shell on the upper part of the nebula.

Heckathorn-Fesen-Gull 1 (HFG1) et Abell 6 sont un duo de nébuleuses planétaires de la constellation de Cassiopée.

L'étoile centrale de HFG1 est une binaire de mag 14.5. Elle laisse derrière elle une queue de gas de 20' au moins. Elle serait agée de 10000 ans environ.

La structure de HFG1 présente un arc de cercle à l'opposé de la queue, c'est à dire dans la direction de déplacement de la nébuleuse, ce qui laisse penser qu'il s'agit d'un front d'onde de choc de matière interagissant avec le millieu interstellaire.

 

Abell 6 est un exemple de nébuleuse planétaire en forme de bulle. Elle reste cependant assez faible (Mag=15). Elle émet plus en OIII qu'en Ha.

M27, also called The Dumbbell Nebula (also known NGC 6853) it is a planetary nebula in the constellation Vulpecula, at a distance of about 1,360 light years.

Stanotte sono andato a letto alle 4.30AM per fotografare il cielo. In questa immagine, nel cuore silenzioso della Vulpecula, a circa 1.200 anni luce da noi, si espande lentamente la Nebulosa Manubrio — M27 — prima nebulosa planetaria mai identificata da occhi umani,

traccia visibile dell’ultimo respiro di una stella simile al nostro Sole. Un guscio di gas ionizzati largo quasi tre anni luce,

che brilla nel tempo come una lanterna sospesa tra i secoli.

Questa immagine, raccolta in 70 minuti di posa attraverso il filtro SVBONY 220 e con con lo SkyWatcher 200/1000, è il tentativo di cogliere la bellezza del cosmo sempre lottando contro le luci della città

The planetary nebula Abell 30, (a.k.a. A30), is located about 5,500 light years from Earth. Close-up views of A30 show X-ray data from NASA's Chandra X-ray Observatory and optical data from the Hubble Space Telescope. A planetary nebula is formed in the late stage of the evolution of a sun-like star, after it expands to become a red giant. In the case of A30, a planetary nebula formed but then the star briefly reverted to being a red giant. The evolution of the planetary nebula then restarted, making it reborn, a special phase of evolution that is rarely seen.

Here's a little experiment. The dotted line is the International Space Station (ISS) passing through the field of view of my small telescope, very near the interesting little object known as NGC 246, a planetary nebula sometimes called the Skull Nebula in the constellation Cetus.

 

This wasn't by chance. Watching for these sorts of coincidences, I consulted the trusty sky simulation software SkySafari and noticed that the path of the station would take it in front of a few interesting features in the sky, in addition to this one: M13, the Great Hercules Globular cluster in Hercules, Vega, the brightest star in Lyra, and The Veil Nebula in Cygnus.

 

Because of the tremendous difference in brightness, I captured the ISS and the nebula field separately. (The ISS is the third brightest object in the night sky, after the Moon and Venus). For the ISS pass, I made a short video with a Nikon Z 6 mirrorless camera and Explore Scientific 102mm f/7 refractor. The image of NGC 246 was made afterward with a ZWO ASI294MC camera and Nikon 80-200mm f/2.8 lens @200mm, 15 6-minute exposures processed in Astro Pixel Processor and Lightroom. The ISS track is in the correct position and scale, composited in Photoshop. In addition, the inset is an enlargement of a few video frames and shows some detail in the ISS.

Two infrared views of NGC 1514. At left is an observation from NASA’s Wide-field Infrared Survey Explorer (WISE). At right is a more refined image from NASA's James Webb Space Telescope.

 

[Image description: Two views of the same planetary nebula cataloged NGC 1514, split down the middle. Both show roughly the same features, an outline of a cylinder tipped to the right with a large blob of material in the middle. At the center of the blob is a bright star. At left is the Wide-field Infrared Survey Explorer (WISE) view. The outlines of the cylinder are orange and thicker, and within it is a bright green irregular cloud with a larger blue central star. This view has hazier lines, and colors that appear to bleed into one another. At right is the view from the James Webb Space Telescope. The outline of the cylinder is clearer with crisp, wispy details. Where the cylinder appears to connect at top left and bottom right, the outline forms shallow V-shapes. It’s a lot easier to see where material begins, ends, and overlaps. In both images, the background of space is black. The WISE image shows bright blue orbs. The Webb image shows tiny pinpoints of light.]

An odd couple that is separated in the sky by less than one degree but which are at least 45 million light years apart in space. The Owl (M97) is a planetary nebula that is a few thousand light years from earth while M108 (on the right) is a spiral galaxy that is perhaps 45 million light years distant. Both of these objects appear in the constellation Ursa Major (a.k.a. “The Big Dipper”).

 

Image capture was done over two evenings in early February 2015 using an unmodified Sony NEX-5N digital camera (ISO 800, 60 seconds x 384, producing a total exposure integration time of 6 hours and 24 minutes). The imaging telescope was a 5” refractor working at an effective focal length of 528mm at f/4.2. The setup also included the use of a light-pollution filter that causes about a two-thirds f-stop loss in broadband light transmission (a necessary "evil" given my significantly light-polluted, red-zone skies).

 

Image processing was done with PixInsight v1.8 and Photoshop CC2014.

The Owl Nebula also known as M97 or NGC 3587 is a planetary nebula approximately 2,030 light years away in the constellation Ursa Major.

Estimated to be about 8,000 years old, it is approximately circular in cross-section with a faint internal structure. The owl-like appearance of the nebula is the result of an inner shell that is not circularly symmetric, but instead forms a barrel-like structure aligned at an angle of 45° to the line of sight.

The 14th magnitude central star has passed the turning point in its evolution and is condensing to form a white dwarf. [Wikipedia]

M97. The Owl planetary nebula is about 3.7 arcminutes across in our sky but is actually 0.91 light years in diameter. It lies about 2600 light years distant. The central star has shed its outer layers which glow either red (hydrogen) or green-blue (oxygen) lit by the intense UV light of the remnant white dwarf star in the centre. Eventually, the star will cool and the gas will expand until the nebula fades away. It estimated that the nebula is about 6000 years old based on its size and expansion rate. Our own Sun may eventually suffer a similar fate.

 

A gravitational effect has formed a constrained tube of gas near the star before it expands into a sphere. We are looking down at about 45 degrees to the axis of the tube, these effects produce an "owl face" from our perspective.

 

Barred spiral galaxy M108 is about 45 million light years away and is almost edge on from our perspective. It’s 8.7 x 2.2 arcminutes diameter in our sky. It lacks a prominent core or bulge but has numerous dark dust lanes. It’s possible to see

a small yellow core at its centre (yellow or red stars tend to be old and mature) brownish dust lanes, pink hydrogen alpha zones and two bright blue "stellar associations” of young intensely bright stars at this magnification.

 

A Type II supernovae was observed here in 1969.

The Dumbbell Nebula (Messier 27, M27 or NGC 6853) is a bright planetary nebula in the constellation Vulpecula. It is easily seen in binoculars and wide-field photographs. The central star is an extremely hot blueish subdwarf. The nebula was created by the dying star ejecting a shell of gas into space. The inset image was further processed to bring out additional detail in the shell.

Planetary nebula HB 5, an end phase of a Sun-like star, was discovered by famous astronomer Edwin Hubble. X-rays from hot gas in HB 5 are detected by Chandra. X-rays from Chandra (blue and white); optical from Hubble (red, purple, blue); radio image from ALMA (yellow and white)

 

Visual Description:

This composite image of the planetary nebula HB 5 resembles a bulbous bow tie in mottled purples. This is a Sun-like star towards the end of its life. At the heart of the nebula, or the brilliant golden white knot of the bow tie, is a recent mass ejection from the dying star. To its right and left are matching bulbous spheres of churning purple gas. Each sphere of gas is several times larger than the exploding knot between them. Also present in the nebula are faint clouds in neon blue and mustard yellow. The blue cloud, most prominent at our upper left, represents X-rays observed by Chandra. The mustard yellow cloud, which highlights the star’s recent mass ejection, represents carbon monoxide gas observed in radio waves by ALMA.

This view of the Butterfly Nebula, NGC 6302, comes from the NASA/ESA Hubble Space Telescope. Compared to its appearance in visible light, the Butterfly Nebula looks gauzy at near-infrared wavelengths. The red colour that’s most prevalent in this view shows light from hydrogen, while green and blue come from iron that has been ionised.

 

This Hubble image highlights the Butterfly Nebula’s bipolar shape, showing how its two lobes spread in opposite directions, forming the ‘wings’ of the butterfly. A dark band of dusty gas poses as the butterfly’s ‘body’. This band is actually a doughnut-shaped torus that we see from the side, hiding the nebula’s central star – the ancient core of a Sun-like star that energises the nebula and causes it to glow. The dusty doughnut may be responsible for the nebula’s insectoid shape by preventing gas from flowing outward from the star equally in all directions.

A dark dust lane runs through the centre of the nebula and two broad clouds emerge from either side of the dust lane like the outstretched wings of a butterfly. The nebula appears cream coloured and most opaque near the centre, then becomes reddish with purple streaks and more translucent out toward the wings of the nebula. There are hundreds of background stars in the image, many of which are visible through the nebula.]

The Helix Nebula (NGC 7293) in the constellation Aquarius. This is a 26 minute exposure (26 x 1 minute) at ISO 3200, low on the horizon for me, so image quality is not that good, was toward the end of the night and never attempted to image it before.

Salut à tous,

 

192h au cœur d'un rémanent de supernova : on parle des restes d'une étoile géante, bien plus massive que notre soleil, dont la vie s'achève de manière cataclysmique en une explosion de matière dont on voit ici les restes. Cette explosion, ou plutôt effondrement, appelé supernova fait partie des évènements les plus spectaculaires de l'univers.

 

Au sein de ce rémanent de supernova (appelé SNR pour SuperNova Remanent), des structures particulières se forment à partir des gaz d'hydrogène (en rouge) et d'oxygène (en bleu), ces structures ont leur propre dénomination et cette image se concentre sur SH2-96 et SH2-94, mais il ne s'agit la que d'une fraction de ce rémanent. Pour prendre la mesure complète de cet objet, voici une image du rémanent complet réalisé par @Yann Saintyhttps://www.astrobin.com/fzzmhu/ notre champ, n'étant que la partie en haut à droite de son image !

 

Mais SH2-96-94 n'était à la base, pas la cible de ce projet, nous avions contacté @Marcel Drechsler pour lui proposer de réaliser une image du catalogue StDr, notre choix s'était porté sur StDr132 (planetarynebulae.net/EN/page_np.php?id=1009) qui se trouve pile aux coordonnées ci :

  

Voyant l'environnement dans lequel se situait cet objet, le signal de StDr au regard du signal des deux objets Sharpless nous n'avons pu résister à la tentation de le photographier ce champ à 750mm de focale avec un capteur APS-C, il nous aura fallu 4 tuiles de 32h de H et 16h de O chacune pour photographier ces deux objets SH2

 

Le champ est d'une richesse incroyable, les gaz s’entremêlent en de chaotiques filaments témoins de la puissance du phénomène qui les ont fait naître. En se promenant dans l'image en haute résolution vous apercevrez peut être quelques petites galaxies en arrière plan

 

Nous ne pouvons toutefois pas publier cette image sans mentionner de nouveau Yann qui nous aura été d'une aide précieuse pour la réalisation de celle ci : tant du point de vue des conseils pour améliorer le rendu de l'image que pour la résolution d'un problème que nous avons rencontré lors de la réalisation de celle-ci : la colorisation des étoiles. Notre couche RVB ayant eu un problème, nous avons pu utiliser celle de Yann et achever complètement ce champ ! Un grand merci à toi !

 

N'hesitez pas encore une fois à parcourir la version détaillée de l'image, de chouettes choses s'y cachent et nous avons eu à coeur de les mettre en relief ! Nous espérons que cette image vous plaira autant qu'à nous ! A très bientôt pour de nouvelles images !

NGC6543 (Cat's Eye Nebula)

A bright planetary nebula in the constellation Draco. The first planetary nebula in my collection, and also my first image on the 10" refractor at Volkssternwarte München.

 

Imaged on 2021-10-31

Telescope: 10" Schaer refractor (f/16, prime focus) @ Volkssternwarte München

Camera: Samsung NX30 (unmodified)

Acquisition: 60x20 s, ISO 1600, 20 darks, no flats

Tracking: equatorial mount, unguided RA tracking

Stacking: Fitswork

Post-processing: Fitswork (wavelets, sharpening), Aurora HDR (stretching), Photoshop (cosmetics, processing artifact removal)

Some new data for this nebula went public yesterday, and... it's different. The observations were almost all narrowband emission lines, and there were a lot of them. Five visible, four near-infrared, two wideband near-infrared. For this image I used only the visible filters. It turned out quite colorful, and quite unlike all the Hubble imagery that came before it. [O III] really wants to dominate the image, but I toned it down quite a bit with a technique I only use rarely, which is to group filters by the similarity the reveal within the object rather than trying to merge all filters into a single image.

 

If you would like to see the old image of this nebula, check here: flic.kr/p/fC7DwR

 

I was interested to see if any more structures were revealed especially in the near-infrared data, like the double rings (it's questionable they are really rings), but it's not nearly as apparent in these data as it was back in the old NICMOS data. The double rings, if that's what they are, are most pronounced in F212N, which is a molecular hydrogen filter. None of the filters for this image reveal quite the same structure that the F212N filter did.

 

The nebula expanded quite a bit in the two decades since the previous HST observations were taken. In terms of this image, the maximum movement amounted to around 8 pixels at WFC3/UVIS resolution (100% zoom of this image). All of the stars moved around, too. The new image is slightly higher resolution, but not much.

 

Explaining the processing further, I took the F673N, F487N, & F343N filters to make a 3-color image. I chose these because none of them was overwhelmingly brighter in any area than the other, but they all do still reveal delicate color separation. Next, I combined the F656N and F502N filters into a 2-color image. The signal for these two filters was much more intense, and they worked nicely together to reveal the fainter structures of the nebula, especially those faint shells emanating gently outward from the nebula in nearly circular formation. The 2-color combination is not especially colorful though, so I used it as a luminosity layer. Stars are always funky in narrowband imagery, so I removed all the stars from the 3-color image, leaving the 2-color luminosity layer to show them.

 

Data from the following proposal were used to create this image:

Nebulosa planetaria - somma di 20 scatti da 5 minuti a 800 ISO. Strumenti: Canon Eos 350D mod.; Schmidt-Newton Meade 203, focale 812, 7 dark, 25 flat. Località: Spinello(Fc). Data: 17/09/2009

This Hubble Space Telescope image captures the beauty of the moth-like planetary nebula NGC 2899. This object has a diagonal, bipolar, cylindrical outflow of gas. This is propelled by radiation and stellar winds from a nearly 22 000 degree Celsius white dwarf at the center. In fact, there may be two companion stars that are interacting and sculpting the nebula, which is pinched in the middle by a fragmented ring or torus – looking like a half-eaten donut. It has a forest of gaseous “pillars” that point back to the source of radiation and stellar winds. The colours are from glowing hydrogen and oxygen. The nebula lies approximately 4,500 light-years away in the southern constellation Vela.

 

[Image description: The planetary nebula NGC 2899 is shaped like a single macaroni noodle, with its edges pointed up, but its edge-on central torus is semi-transparent in the middle. The top and bottom edges are thick and orange. The center is semi-transparent blue and green. The wider central region looks roughly like a moth, also filled with semi-transparent blue and green. There are two pinpoint-like white stars with diffraction spikes toward the center. Immediately below them, slightly toward the right, is a smaller blue orb, a central star. The next layer of gas and dust is whiter, with some thicker pillars that look like they are rising up at bottom center. The colour fades into reds and purples, and then to orange ]

This planetary nebula has a very unusual shape.

The central star is moving, and this causes the ejected material to pile up in one direction. This part is brighter.

It is interesting to compare the hydrogen to the sulfur exposures.

I have included both so that you can use the arrow keys to move between them.

 

The planetary nebula is interacting with the interstellar medium. Long exposures show faint details of the planetary nebula.

The rest of the circle at the lower left as well as extra material below this are also barely visible.
