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

By pushing NASA’s Hubble Space Telescope to its limits, an international team of astronomers has shattered the cosmic distance record by measuring the farthest galaxy ever seen in the universe. This surprisingly bright infant galaxy, named GN-z11, is seen as it was 13.4 billion years in the past, just 400 million years after the Big Bang. GN-z11 is located in the direction of the constellation of Ursa Major.

Another wet and windy day so yet another indoor shot. Oil and water with some wrapping paper underneath. It's not perfect, but I liked the shapes and colours in this one.
Resembling an opulent diamond tapestry, this image from NASA’s Hubble Space Telescope shows a glittering star cluster that contains a collection of some of the brightest stars seen in our Milky Way galaxy. Called Trumpler 14, it is located 8,000 light-years away in the Carina Nebula, a huge star-formation region. Because the cluster is only 500,000 years old, it has one of the highest concentrations of massive, luminous stars in the entire Milky Way. The small, dark knot left of center is a nodule of gas laced with dust, and seen in silhouette.

As seen in 2022, Uranus’s north pole shows a thickened photochemical haze that looks similar to the smog over cities. Several little storms can be seen near the edge of the polar haze boundary. Hubble has been tracking the size and brightness of the north polar cap and it continues to get brighter year after year. Astronomers are disentangling multiple effects — from atmospheric circulation, particle properties, and chemical processes — that control how the atmospheric polar cap changes with the seasons. At the Uranian equinox in 2007, neither pole was particularly bright. As the northern summer solstice approaches in 2028 the cap may grow brighter still, and will be aimed directly toward Earth, allowing good views of the rings and the north pole; the ring system will then appear face-on. This image was taken on 10 November 2022.
[Image description: Uranus appears tipped on its side. Set against a black background, the planet is mainly coloured cyan. It looks like a flat circle outlined with a pinkish gray limb. A faint, pink ring encircles the planet nearly vertically. The faint ring appears to be almost face on. A large area of white coves much of the right side of the planet.]

NGC7380 is also known as the “Wizard Nebula” and as Sharpless 142 (Sh2-142). This large nebula is in Cepheus and the gas surrounds open star cluster NGC7380. The nebula is fairly close to us at about 8,000 light years. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans about 100 light years, making it appear larger than the angular size of the Moon.

NGC 4402 and edge on spiral galaxy in the constellation Virgo.
This Data was taken from the Hubble Legacy Archive and processed by me.
First time trying out processing Hubble Data. I still need to find a way of removing the hotpixels. They are especially noticable in a stripe from the top to the bottom in the middle of the image. This is because Hubbles Sensor is made up of two sensors and that stripe is the seam between these two.

This image from the NASA/ESA Hubble Space Telescope shows the barred spiral galaxy NGC 7496, which lies over 24 million light-years away in the constellation Grus. This constellation, whose name is Latin for crane, is one of four constellations collectively known as the Southern Birds. The others are Pavo, Phoenix and Tucana, which depict a peacock, phoenix, and toucan respectively. The rest of the night sky is also home to a flock of ornithological constellations, including an eagle (Aquilla), swan (Cygnus), crow (Corvus), and dove (Columba). This image comes from a collection of observations delving into the relationship between young stars and the cold, dense clouds of gas in which they form. In addition to observations with Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys, the astronomers behind this project gathered data using the Atacama Large Millimeter/submillimeter Array (ALMA), one of the largest radio telescopes in the world. As well as shedding light on the speed and efficiency of star formation in a variety of galactic environments, this project is also creating a treasury of data incorporating both Hubble and ALMA observations. This treasure trove of data from two of the world’s most capable observatories will contribute to wider research into star formation, as well as paving the way for future science with the James Webb Space Telescope.

Dans la constellation d'Andromède (Andromeda), à 300 millions d'a.l. de la Terre, les galaxies en interaction Arp 273 se situent à 100 000 a.l. l'une de l'autre et se sont rencontrées, il y a quelques centaines de millions d'années, quand la galaxie UGC 1813 a traversé les bras extérieurs de la galaxie spirale UGC 1810. Les bras de la grande galaxie ont été étirés par l'attraction gravitationnelle de la petite, le gaz et la poussière compressés ayant alors formé des étoiles bleues, très chaudes. La plus grande des deux est à peu près cinq fois plus massive que sa compagne, son disque étant déformé à la suite de ses interactions gravitationnelles avec son compagnon du bas (cf.wikipédia).

This image from the Hubble Deep Ultraviolet Legacy Survey encompasses 12,000 star-forming galaxies in the constellation Fornax - a region known as the GOODS-South field. With the addition of ultraviolet light imagery, astronomers using NASA/ESA's Hubble Space Telescope captured the largest panoramic view of the fire and fury of star birth in the distant universe. The busiest star-forming period in the cosmos happened about three billion years after the big bang.
So far, ultraviolet light has been the missing piece of the cosmic puzzle. Now, combined with data in infrared and visible light from Hubble and other space- and ground-based telescopes, astronomers have assembled the most comprehensive portrait yet of the universe’s evolutionary history. The image straddles the gap between the very distant galaxies, which can only be viewed in infrared light, and closer galaxies, which can be seen across different wavelengths. The light from distant star-forming regions in remote galaxies started out as ultraviolet, but the expansion of the universe has shifted the light into infrared wavelengths. By comparing images of star formation in the distant and nearby universe, astronomers can get a better understanding of how nearby galaxies grew from small clumps of hot, young stars long ago.

More info:
Hubble’s payload computer, which controls and coordinates the observatory’s onboard science instruments, halted suddenly on June 13. When the main computer failed to receive a signal from the payload computer, it automatically placed Hubble’s science instruments into safe mode. That meant the telescope would no longer be doing science while mission specialists analyzed the situation.
In response to the anomaly, NASA began a switch to backup spacecraft hardware on Hubble in response to an ongoing problem with its payload computer. This was a multi-day event.
Science observations restarted the afternoon of Saturday, July 17.

Astronomers have used NASA's Hubble Space Telescope to photograph the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory's launch aboard the space shuttle Discovery on April 24, 1990.
Looking like an apparition rising from whitecaps of interstellar foam, the iconic Horsehead Nebula has graced astronomy books ever since its discovery more than a century ago. The nebula is a favorite target for amateur and professional astronomers. It is shadowy in optical light. It appears transparent and ethereal when seen at infrared wavelengths. The rich tapestry of the Horsehead Nebula pops out against the backdrop of Milky Way stars and distant galaxies that easily are visible in infrared light.

Recent observations revealing the many-armed, beautiful spiral galaxy NGC 2336 as only Hubble can. The imagery used to create this image was taken in January 2020. Meanwhile, the Chandra X-ray Observatory is also tasked with looking at this galaxy, though I haven't looked into the details of that, yet.
Edit: Checked on CXO observations, and so far none yet, but I did notice that of the proposed 200 kilosecond time, they only gave Dr. Antoniou 50 ks. Ouch! Here's hoping that's enough.
Data from the following proposal was used to create this image:

Note there are a number of blank areas in the image where data were absent. I filled those with background-matched noise to make them visually unobtrusive. Some other areas also lack a full range of color, being only covered by 1-2 filters.
The pixel scale is 0.05 arcseconds per pixel.

This colourful image shows a cosmic lighthouse known as the Egg Nebula, which lies around 3000 light-years from Earth. The image, taken with the NASA/ESA Hubble Space Telescope, has captured a brief but dramatic phase in the life of a Sun-like star.
The Egg Nebula is a ‘preplanetary nebula’. These objects occur as a dying star’s hot remains briefly illuminates material it has expelled, lighting up the gas and dust that surrounds it.
These objects will one day develop into planetary nebulas which, despite the name, have nothing at all to do with planets. They gained their rather misleading title because when they were discovered in the 18th century they resembled planets in our Solar System when viewed through a telescope.
Although the dying star is hidden behind the thick dust lane that streaks down the centre of this image, it is revealed by the four lighthouse-like beams clearly visible through the veil of dust that lies beyond the central lane.
The light beams were able to penetrate the central dust lane due to paths carved out of the thick cloud by powerful jets of material expelled from the star, although the cause of these jets is not yet known.
The concentric rings seen in the less dense cloud surrounding the star are due to the star ejecting material at regular intervals – typically every hundred years – during a phase of the star’s evolution just prior to this preplanetary nebula phase. These dusty shells are not usually visible in these nebulas, but when they are it provides astronomers with a rare opportunity to study their formation and evolution.
The fleeting nature of this phase in a star’s life – which occupies only a few thousand of the star’s few billion years of existence – and the fact that they are fairly faint make it rare to capture them in action. In fact, the Egg Nebula, the first of its kind to be identified, was discovered only 40 years ago.
This image was taken with Hubble’s Advanced Camera for Surveys. Artificial colours are used to represent how the light from the star reflects off the dust – this can tell scientists about the physical properties of the dust.
The image combines observations with three different polarising filters, each showing light vibrating at a specific orientation. The three filters have been coloured red, blue and green, and all three observations were made at a wavelength of 0.606 microns. The image spans 1.2 light-years. North is to the right and east is up.
This image was previously published on the NASA Hubble Heritage website.

This festive NASA Hubble Space Telescope image resembles a holiday wreath made of sparkling lights. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star. The super star is ten times more massive than our sun and 200 times larger.
RS Puppis rhythmically brightens and dims over a six-week cycle. It is one of the most luminous in the class of so-called Cepheid variable stars. Its average intrinsic brightness is 15,000 times greater than our sun’s luminosity.
The nebula flickers in brightness as pulses of light from the Cepheid propagate outwards. Hubble took a series of photos of light flashes rippling across the nebula in a phenomenon known as a "light echo." Even though light travels through space fast enough to span the gap between Earth and the moon in a little over a second, the nebula is so large that reflected light can actually be photographed traversing the nebula.
By observing the fluctuation of light in RS Puppis itself, as well as recording the faint reflections of light pulses moving across the nebula, astronomers are able to measure these light echoes and pin down a very accurate distance. The distance to RS Puppis has been narrowed down to 6,500 light-years (with a margin of error of only one percent).
The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center in Greenbelt, Md., manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Md., conducts Hubble science operations. STScI is operated by the Association of Universities for Research in Astronomy, Inc., in Washington, D.C.

NGC 4298 is a spiral galaxy located about 53 million light-years away in the constellation Coma Berenices. The galaxy was discovered by astronomer William Herschel on April 8, 1784 and is a member of the Virgo Cluster.

Many celestial objects are beautiful – swirling spiral galaxies or glittering clusters of stars are notable examples. But some of the most striking scenes are created during the death throes of intermediate-mass stars, when great clouds of superheated gas are expelled into space. These dying breaths form planetary nebulas like NGC 6302, captured here in this image from the NASA/ESA Hubble Space Telescope.
Known perhaps more appropriately as the Bug or Butterfly Nebula, this complex nebula lies roughly 3800 light-years away from us within the Milky Way. It was formed when a star around five times the mass of our Sun became a red giant, ejected its outer layers, and became intensely hot. Its distinctive shape classifies it as a bipolar nebula, where fast-moving gas can escape more easily from the poles of the dying star than from around its equator. This creates a lobed structure reminiscent of an hourglass or, as in this case, a giant cosmic butterfly.
While this image is beautiful in its own right, the mix of colours actually tells us a lot about physical conditions within the nebula.
The red edges of the butterfly wings represent areas that emit light from the element nitrogen, due to the relatively low temperatures there. Conversely the white splashes closer to the nebula's centre pinpoint light emitted by the element sulphur, marking regions of higher temperature and colliding gases closer to the central star.
This hot gas was expelled from the star and collided with slower-moving gas in its path, creating rippling shock waves through the nebula. An example of such a shock wave can be seen in the well-defined white blob towards the top right of the image.
Other colours identify emission from oxygen, helium and hydrogen gases. The observations making up this composite image were taken in optical and ultraviolet light on 27 July 2009, using Hubble's Wide Field Camera 3. The Principal Investigators for the observing programme are K. Noll , H. Bond and B. Balick.
This image was originally released in September 2009 on the NASA Hubblesite.

NGC 1300 est une galaxie spirale barrée (deux galaxies sur trois en contiennent une) dans la constellation de l'Éridan (Eridanus), à environ 72 a.l. de la Voie lactée. Elle est la plus grosse et la plus brillante d'un groupe qui porte son nom et compte au moins 4 galaxies, les trois autres étant NGC 1297, PGC 12680 et ESO 549-5. Dans les bras, le disque, le bulbe et le noyau de la galaxie se trouvent des supergéantes bleues et rouges, des amas d'étoiles et des régions rosâtres de formation d'étoiles. Cette spirale s'étend sur environ 3000 a.l. Seules les galaxies munies d'un longue barre centrale semblent avoir un disque interne présentant une structure spirale, une spirale dans la spirale. Le gaz dans la barre peut être canalisé vers le centre, prendre la forme d'une spirale et éventuellement nourrir un trou noir. Mais NGC 1300 ne présente pas de noyau actif, soit parce qu'il n'y a pas de trou noir ou que peu de matière y tombe. Prise par le télescope spatial Hubble en septembre 2004, c'est l'une des images les plus grandes (1,22 par 2,44 m) réalisées à ce jour (cf. wikipédia).

This image assembles the largest and most comprehensive "history book" of galaxies into one single sweep, including 16 years of observations from NASA's Hubble Space Telescope.
The Hubble Legacy Field mosaic, created from nearly 7,500 individual exposures, provides a deep portrait of the distant universe, containing 265,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the big bang. The faintest and farthest galaxies are just one ten-billionth the brightness of what the human eye can see. The universe's evolutionary history is also chronicled in this one sweeping image. The portrait shows how galaxies change over time, building themselves up to become the giant galaxies seen in the nearby universe.
This ambitious endeavor also includes observations taken by several Hubble deep-field surveys, including the eXtreme Deep Field (XDF), the deepest view of the universe. The wavelength range stretches from ultraviolet to near-infrared light, capturing the key features of galaxy assembly over time.

NASA image release September 25, 2012
Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe.
Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full moon.
The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 2003 and 2004. By collecting faint light over many hours of observation, it revealed thousands of galaxies, both nearby and very distant, making it the deepest image of the universe ever taken at that time.
The new full-color XDF image is even more sensitive, and contains about 5,500 galaxies even within its smaller field of view. The faintest galaxies are one ten-billionth the brightness of what the human eye can see.

Data from the Hubble space telescope, processed in PixInsight.
Based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA).

A color mosaic showing the Triangulum Galaxy. It looks very noisy, but the noise is actually individual stars being resolved. There is a warm yellow core, and cool cyan periphery. The spiral is not strongly defined, but still discernible. Splotches of reddish dust are scattered about. Blue clouds of concentrated star formation are seen mainly in the arms. Many, many clusters of stars and globular clusters speckle the image. A few bright foreground stars from our Milky Way are intruding upon the image, but not so many that they are very distracting. At the edge are some zig zagging boundaries where the edge of the mosaic is. Areas which were empty have been filled with a random noise texture that matches somewhat with the galaxy to greatly reduce visual distraction.
I started working on this years ago, but got stuck at some point just not feeling enough momentum to want to clean up all of the artifacts. Finally got through that last week and finished it up. There's a maximum image size of 200MB at Flickr, so this is a 40% resize of the mosaic.
I assembled this mosaic manually, but you can actually download already-assembled mosaic files here from the HLSP page:
archive.stsci.edu/hlsp/phatter
A link to a gigapan is available.
Processing note: Around the edges are places where the image is only two filters rather than all four. Where near-infrared F160W had missing data, it was replaced by F814W data. I applied a Gaussian blur to make it more closely resemble the F160W data. Similarly, where F336W data were missing, I filled those areas with F475W. For that I simply adjusted the curves and added some noise to make the blending nicer. Yes, I actually "degraded" the data in both cases to make it look nicer. In my defense that's way better than faking it, or cutting it off completely.

New images of the Phantom Galaxy, M74, showcase the power of space observatories working together in multiple wavelengths. On the left, the Hubble Space Telescope’s view of the galaxy ranges from the older, redder stars towards the centre, to younger and bluer stars in its spiral arms, to the most active stellar formation in the red bubbles of H II regions.
On the right, the James Webb Space Telescope’s image is strikingly different, instead highlighting the masses of gas and dust within the galaxy’s arms, and the dense cluster of stars at its core. The combined image in the centre merges these two for a truly unique look at this “grand design” spiral galaxy. Scientists combine data from telescopes operating across the electromagnetic spectrum to truly understand astronomical objects. In this way, data from Hubble and Webb compliment each other to provide a comprehensive view of the spectacular M74 galaxy.

Arms carved of brown filaments spiral out from a bright galactic core. The arms have pops of pink, which are star-forming regions, and there are blue stars throughout. The middle view contained combined Webb and Hubble data. Lacy red filaments spiraling out of the center of the galaxy are overlaid over a black field speckled with tiny blue stars. The red filaments contain pops of bright pink, which are star-forming regions. Lighter oranges in the red dust mean that dust is hotter. Heavier older stars closer to the center of the galaxy are cyan and green, and contribute to a greenish glow at the core. At right is a mid-infrared image from Webb. Delicate gray filaments spiral outwards from the center. These arms are traced by blue and bursts of pink, which are star-forming regions. A cluster of young stars glow blue at the very heart of the galaxy.
In the centre of this image, taken with the NASA/ESA Hubble Space Telescope, is the galaxy cluster SDSS J1038+4849 — and it seems to be smiling.
You can make out its two orange eyes and white button nose. In the case of this “happy face”, the two eyes are very bright galaxies and the misleading smile lines are actually arcs caused by an effect known as strong gravitational lensing.
Galaxy clusters are the most massive structures in the Universe and exert such a powerful gravitational pull that they warp the spacetime around them and act as cosmic lenses which can magnify, distort and bend the light behind them. This phenomenon, crucial to many of Hubble’s discoveries, can be explained by Einstein’s theory of general relativity.
In this special case of gravitational lensing, a ring — known as an Einstein Ring — is produced from this bending of light, a consequence of the exact and symmetrical alignment of the source, lens and observer and resulting in the ring-like structure we see here.
Hubble has provided astronomers with the tools to probe these massive galaxies and model their lensing effects, allowing us to peer further into the early Universe than ever before. This object was studied by Hubble’s Wide Field and Planetary Camera 2 (WFPC2) and Wide Field Camera 3 (WFC3) as part of a survey of strong lenses.

These three images are of the central region of the magnificent spiral galaxy M100, taken with three generations of the Hubble Space Telescope cameras that were sequentially swapped out aboard the telescope, and document the consistently improving capability of the observatory.
The image on the left was taken with the Wide Field/Planetary Camera 1 in 1993. The photo is blurry due to a manufacturing flaw (called spherical aberration) in Hubble's primary mirror. Celestial images could not be brought into a single focus. [Credit: NASA, ESA, and Judy Schmidt]
The middle image was taken in late 1993 with Wide Field/Planetary Camera 2 that was installed during the Dec. 2-13 space shuttle servicing mission (SM1, STS-61). The camera contained corrective optics to compensate for the mirror flaw, and so the galaxy snapped into sharp focus when photographed. [Credit: NASA, ESA, and J. DePasquale (STScI)]
The image on the right was taken with a newer instrument, Wide Field Camera 3, that was installed on Hubble during the space shuttle Servicing Mission 4 in May 2009. [Credit: NASA, ESA, and Judy Schmidt]
In celebration of the 25th anniversary of NASA's first space servicing mission to Hubble, these comparison photos of one of the telescope's first targets are being released today.
NASA Goddard Space Flight Center enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics. Goddard plays a leading role in NASA’s accomplishments by contributing compelling scientific knowledge to advance the Agency’s mission.
