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.

Description: The Orion Nebula is one of the closest star formation regions from Earth at a distance of 1,500 light years. A favorite for amateur astronomers and casual sky watchers, Orion is seen as never before in this composite image created from Chandra and Hubble data. The wispy filaments seen by Hubble (pink and purple) are clouds of gas and dust that provide the material used as fuel by young stars. The bright point-like sources (blue and orange) are newly formed stars captured in X-ray light by Chandra. These fledgling stars are seen to flare in their X-ray intensity, which suggests that our Sun had many violent and energetic outbursts when it was much younger.

NASA's Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, is the most sophisticated X-ray observatory built to date. The mirrors on Chandra are the largest, most precisely shaped and aligned, and smoothest mirrors ever constructed. Chandra is helping scientists better understand the hot, turbulent regions of space and answer fundamental questions about origin, evolution, and destiny of the Universe. The images Chandra makes are twenty-five times sharper than the best previous X-ray telescope. NASA's Marshall Space Flight Center in Huntsville, Ala., manages the Chandra program for NASA's Science Mission Directorate in Washington. The Smithsonian Astrophysical Observatory controls Chandra science and flight operations from the Chandra X-ray Center in Cambridge, Massachusetts.

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.

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.

New Chandra observations have been used to make the first detection of X-ray emission from young stars with masses similar to our Sun outside our Milky Way galaxy. The Chandra observations of these low-mass stars were made of the region known as the "Wing" of the Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors. In this composite image of the Wing the Chandra data is shown in purple, optical data from the Hubble Space Telescope is shown in red, green and blue and infrared data from the Spitzer Space Telescope is shown in red. Astronomers call all elements heavier than hydrogen and helium - that is, with more than two protons in the atom's nucleus - "metals". The Wing is a region known to have fewer metals compared to most areas within the Milky Way. The Chandra results imply that the young, metal-poor stars in NGC 602a produce X-rays in a manner similar to stars with much higher metal content found in the Orion cluster in our galaxy.
These cosmic ribbons of gas have been left behind by a titanic stellar explosion called a supernova. DEM L249 is thought to be the remnant of a Type 1a supernova, the death of a white dwarf star. White dwarf stars are usually stable, but in a binary system ― two stars orbiting each other ― a white dwarf can gravitationally pull so much matter from its companion that it reaches critical mass and explodes.
DEM L249, located in the Large Magellanic Cloud, is an unusual supernova remnant. Astronomers using NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton found its gas was hotter and shone brighter in the x-rays than the remnant of a typical Type 1a supernova. Astronomers suspect DEM L249’s white dwarf star was more massive than expected ― heavier stars expel more gas ― which also means it would have died earlier in its lifecycle.
Hubble took this image while searching for surviving companions of white dwarf stars that went supernova in the Large Magellanic Cloud.

This image from the 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.

Le voyage du télescope spatial Hubble a commencé bien avant son lancement. En 1946, Lyman Spitzer, professeur à l'Université de Yale, a rédigé un article intitulé Avantages astronomiques d'un observatoire extraterrestre dans l'espoir d'obtenir un soutien pour un télescope spatial. Après avoir reçu l'appui de la NASA, le programme Large Telescope Spatial a été créé et les recherches ont commencé sur les éléments nécessaires à la construction et au lancement d'un grand télescope dans l'espace. Trente et un ans après la publication du document de Spitzer, le Congrès a finalement accepté la proposition et accordé un financement au programme. Le télescope a été nommé télescope spatial Hubble (HST) en 1983 pour rendre hommage au célèbre astronome Edwin P. Hubble qui a prouvé que l’univers était en expansion. Déployé en 1990 et orbitant à 340 km de la surface de la Terre, HST n'était pas entièrement opérationnel en raison d'un miroir optique de taille incorrecte. Au cours des 19 dernières années, les équipages de la navette spatiale ont effectué cinq missions de service afin de corriger le problème optique initial et de mettre à jour sa technologie. Réplique exacte du télescope, HST est suspendue au plafond entre deux étages, comme si il était en orbite avec panneaux solaires étendus ( de la taille d’un autobus scolaire). Le Hubble Theatre raconte la mission de réparation effectuée par l’équipage d’Atlantis en 2009.
The Hubble Space Telescope's journey began well before its launch. In 1946, Lyman Spitzer, a professor at Yale University, wrote an article entitled Astronomical Benefits of an Extraterrestrial Observatory in the Hope of Obtaining Support for a Space Telescope. After receiving support from NASA, the Large Telescope Spatial program was created and research began on the elements needed to build and launch a large telescope in space. Thirty-one years after the publication of Spitzer's document, Congress finally accepted the proposal and granted funding to the program. The telescope was named the Hubble Space Telescope (HST) in 1983 to pay tribute to the famous astronomer Edwin P. Hubble who proved that the universe was expanding. Deployed in 1990 and orbiting 340 km from the Earth's surface, HST was not fully operational due to an optical mirror of an incorrect size. Over the last 19 years, Space Shuttle crews have completed five service missions to correct the initial optical problem and update its technology. An exact replica of the telescope, HST is suspended from the ceiling between two floors, as if it were in orbit with extended solar panels (the size of a school bus). The Hubble Theater tells the repair mission performed by the crew of Atlantis in 2009.
Just messing around. NGC 6543 is a bright planetary nebula in the constellation of Draco. Previously I have done a blue version of this, but it is probably more appropriate for it to be cyan or green due to the [OIII] emission.
Some notes on the processing: I combined High Resolution Channel (HRC) and Wide Field Channel (WFC) data to create a more detailed image than before, at least in the brightest parts of the nebula. Furthermore, one of the difficulties with these observations I hadn't realized before is that they were made to test Hubble's ramp filters, and the ramp filter info is buried in the image headers where you have to know to look. I've included it in the channel data this time. The ramp follows the pound sign.

This picture, taken by the NASA/ESA Hubble Space Telescope’s Wide Field Planetary Camera 2 (WFPC2), shows a galaxy known as NGC 6872 in the constellation of Pavo (The Peacock). Its unusual shape is caused by its interactions with the smaller galaxy that can be seen just above NGC 6872, called IC 4970. They both lie roughly 300 million light-years away from Earth. From tip to tip, NGC 6872 measures over 500 000 light-years across, making it the second largest spiral galaxy discovered to date. In terms of size it is beaten only by NGC 262, a galaxy that measures a mind-boggling 1.3 million light-years in diameter! To put that into perspective, our own galaxy, the Milky Way, measures between 100 000 and 120 000 light-years across, making NGC 6872 about five times its size. The upper left spiral arm of NGC 6872 is visibly distorted and is populated by star-forming regions, which appear blue on this image. This may have been be caused by IC 4970 recently passing through this arm — although here, recent means 130 million years ago! Astronomers have noted that NGC 6872 seems to be relatively sparse in terms of free hydrogen, which is the basis material for new stars, meaning that if it weren’t for its interactions with IC 4970, NGC 6872 might not have been able to produce new bursts of star formation. A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Judy Schmidt.
This beautiful image is the core of galaxy NGC 4535! This galaxy is located in the constellation Virgo about 54 million light-years away. It is a barred spiral galaxy and while only two arms are shown near the core, there are many more that spiral off in the whole galaxy!

It is interesting to note that instead of being only the second Hubble, this is actually the forth space-going craft to be given that name. The first two were telescopes, and the third was a space station outfitted with a telescope. This spaceship is the first mobile research station outfitted with two telescopes, which give it stereoscopic image and movie capabilities, along with the ability to capture 3D models of planets, asteroids, stars, and almost anything else. However, the twin telescopes provided a field day for conspiracy theorists when they were announced. There were claims that the cylinders were not actually telescopes, but multi-wavelength energy weapons. While it is certainly true that the mysterious tubes on the back of the ship deal with light all across the spectrum, both visible and otherwise, the Coalition for Extraterrestrial Discovery and Colonization, the builders of the Hubble II, has declined to say to what extent.

On 25 June 2023, the NASA/ESA/CSA James Webb Space Telescope turned to famed ringed world Saturn for its first near-infrared observations of the planet. The initial imagery from Webb’s NIRCam (Near-Infrared Camera) is already fascinating researchers. Saturn itself appears extremely dark at this infrared wavelength observed by the telescope, as methane gas absorbs almost all of the sunlight falling on the atmosphere. However, the icy rings stay relatively bright, leading to the unusual appearance of Saturn in the Webb image. This image was taken as part of Webb Guaranteed Time Observation program 1247. The program included several very deep exposures of Saturn, which were designed to test the telescope’s capacity to detect faint moons around the planet and its bright rings. Details in the orbital characteristics of newly discovered moons could help scientists put together a more complete picture of the current system of Saturn, as well as its past. This new image of Saturn clearly shows details within the planet’s ring system, along with several of the planet’s moons – Dione, Enceladus, and Tethys. Additional deeper exposures (not shown here) will allow the team to probe some of the planet’s fainter rings, not visible in this image, including the thin G ring and the diffuse E ring. Saturn’s rings are made up of an array of rocky and icy fragments – the particles range in size from smaller than a grain of sand to a few as large as mountains on Earth. Researchers recently used Webb to explore Enceladus, and found a large plume jetting from the southern pole of the moon that contains both particles and plentiful amounts of water vapor – this plume feeds Saturn’s E ring. Saturn’s atmosphere also shows surprising and unexpected detail. This is the first time that the planet’s atmosphere has been seen with such clarity at this particular wavelength (3.23 microns). The large, dark, diffuse structures in the northern hemisphere do not follow the planet’s lines of latitude, so this image is lacking the familiar striped appearance that is typically seen from Saturn’s deeper atmospheric layers. The patchiness is reminiscent of large-scale planetary waves in the stratospheric aerosols high above the main clouds, potentially similar to those seen in early Webb NIRCam observations of Jupiter. When comparing the northern and southern poles of the planet in this image, the differences in appearance are typical with known seasonal changes on Saturn. For example, Saturn is currently experiencing northern summertime, with the southern hemisphere emerging from the darkness at the end of a winter. However, the northern pole is particularly dark, perhaps due to an unknown seasonal process affecting polar aerosols in particular. A tiny hint of brightening towards the edge of Saturn’s disk might be due to high-altitude methane fluorescence (the process of emitting light after absorbing light), emission from the trihydrogen ion (H3+) in the ionosphere, or both; spectroscopy from Webb could help confirm this. Missions like NASA’s Pioneer 11, Voyagers 1 and 2, the Cassini spacecraft, and the NASA/ESA Hubble Space Telescope have tracked Saturn’s atmosphere and rings for many decades. These observations from Webb are just a hint at what this observatory will add to Saturn’s story in the coming years as the science team delves deep into the data to prepare peer-reviewed results. Note: This content highlights data from Webb science in progress, which has not yet been through the peer-review process. [Image description: Image has a mostly dark background and at the center is a dark orange brownish circle, surrounded by several blazing bright, thick, horizontal whiteish rings. This is Saturn and its rings. There are three tiny orange dots in the image — one to the upper left of the planet, one to the direct left of the planet, and the lower left of the planet. They are the moons Dione, Enceladus, and Tethys.]
The Carina Nebula NGC 3372 is observable to viewers in the southern hemisphere. It is about 8,500 light years from Earth and has a diameter of about 230 light years. The nebula is a very active stellar factory that is forming new stars primarily from hydrogen and other trace elements composed of interstellar gas.
The photo above shows the Carina Nebula produced using the Hubble Palette which was develop by the imaging team of the Hubble Space Telescope. Instead of using wideband red, green, and blue filters to capture all of the colors of the visible spectrum, the Hubble Palette uses three different narrowband band scientific filters: singly ionized sulfur (SII), singly ionized hydrogen (HII), and doubly ionized oxygen (OIII). Unlike the wideband true color filters that capture large swaths of color data, the scientific filters capture only 3 very small slices of the visible spectrum. The Hubble Palette maps the SII data into the red channel, the HII data into the green channel, and the OIII data into the blue channel in the astroimaging software used to process the tricolor filter data into a single false colored image like the one shown above. This color mapping is known as the chromatic ordering of the narrowband data across the visible spectrum.
The false colored images created using the Hubble Palette produce high color contrast in the image of NGC 3372 making the regions of the nebula composed of sulfur, hydrogen, and oxygen stand out starkly. The narrowband image almost has a 3D appearance to it in comparison to a wideband true color image which has a softer, gradual contrast that lessens the appearance of the transitions between different regions of the nebula in terms of contrast. In this sense, the Hubble Palette false color image of the nebula is another visualization tool to present our eyes with a somewhat different perspective and an added comprehension of the structure and composition of NGC 3372 in greater detail beyond that of a true color image alone.
Where the Hubble Palette of false colors depicts multiple gas compositions, the mixing of the colors produces varied brown, gold, green and blue hues depending on the exact concentration of the 3 mixed gases in different regions of the nebula. In a sense, the Hubble Palette false colors opens the door to placing an abstract artistic dimension into the visual representation of a scientific object. False color palettes are used on a regular basis in astrophotography to expand the visual perspective of nebulae by expanding the color options to be used on an astrophotographer’s cosmic canvas while expanding the repertoire of “pretty cosmic pictures”. Note that uses of narrowband data alone causes stars to take on false colors that are different than those of wideband true color images.
The Telescope Live CHI-6 astrograph used to the gather the data is located at the el Sauce Observatory in Chile and is optically composed of an Officina Stellara RH200 200 mm (8 inch) diameter reflecting telescope with a photographic speed of f/3. The imaging system attached to CHI-6 is a Finger Lakes Instrumentation FLI ML PL16200 Monochrome CCD astronomical imaging camera. AstroDon narrowband scientific color filters (SII, HII, and OIII) were inserted between the telescope and the camera to acquire the complete set of imaging data used to make the final false color data of my Flickr photo. The astrograph is mounted on an l Astro-Physics 1200GOTO German Equatorial Mount.
Thirteen 10-minute exposures were taken through the SII, HII, and OIII narrowband filters for a total of 2.1 hours of data collection. The 275 MB of imaging data was download to my home PC for processing. Three software programs were used to convert the data into the above image. These are Astro Pixel Processor, PixInsight, and Adobe Photoshop 2021.

Située dans la constellation du Triangle (Triangulum) à 23 millions d'a.l. de la Voie lactée, la galaxie spirale barrée IC 1727 est actuellement en interaction avec son voisin proche NGC 672 (ici hors du cadre). Les interactions de la paire ont déclenché des phénomènes particuliers et intrigants au sein des deux objets, plus particulièrement dans IC 1727. La structure de la galaxie est visiblement tordue et asymétrique, son noyau lumineux ayant été traîné hors du centre. Les galaxies en interaction comme celles-ci ont souvent des signes de formation intense d’étoiles, épisodiques mais connus sous le nom de rafales d’étoiles, et renferment en conséquence des amas nouvellement formés. Ces rafales sont causées par la rotation gravitationnelle, la redistribution et le compactage du gaz et de la poussière. En fait, les explosions simultanées de formation d’étoiles se sont produites dans ces deux galaxies il y a 20-30 et 450-750 millions d’années (cf. site Hubble).

The life of a planetary nebula is often chaotic, from the death of its parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such planetary nebula, located in the constellation of Scorpius (The Scorpion).
The oblate shells of ESO 455-10, previously held tightly together as layers of its central star, not only give this planetary nebula its unique appearance, but also offer information about the nebula. Seen in a field of stars, the distinct asymmetrical arc of material over the north side of the nebula is a clear sign of interactions between ESO 455-10 and the interstellar medium.
The interstellar medium is the material such as diffuse gas between star systems and galaxies. The star at the center of ESO 455-10 allows Hubble to see the interaction with the gas and dust of the nebula, the surrounding interstellar medium, and the light from the star itself. Planetary nebulae are thought to be crucial in galactic enrichment as they distribute their elements, particularly the heavier metal elements produced inside a star, into the interstellar medium which will in time form the next generation of stars.

A team of astronomers using NASA’s Hubble Space Telescope reported the discovery of another moon orbiting the icy dwarf planet Pluto on this day in 2012. The discovery increased the number of known moons orbiting Pluto to five.
The team was using Hubble’s powerful vision to scour the Pluto system to uncover potential hazards to the New Horizons spacecraft. Moving past the dwarf planet at a speed of 30,000 miles per hour, New Horizons could have been destroyed in a collision with even a BB-shot-size piece of orbital debris.
Pluto’s largest moon, Charon, was discovered in 1978 in observations made at the United States Naval Observatory in Washington, D.C. Hubble observations in 2006 uncovered two additional small moons, Nix and Hydra. In 2011 another moon, P4, was found in Hubble data.
Provisionally designated S/2012 (134340) 1, the latest moon was detected in nine separate sets of images taken by Hubble’s Wide Field Camera 3 on June 26, 27, 29, and July 7 and 9.
