NASA’s Hubble Space Telescope spacecraft was built by Lockheed Missiles Space Corporation (now Lockheed Martin) in its Sunnyvale, California facility. Since the 1990 launch, Lockheed Martin personnel located at NASA's Goddard Space Flight Center, have helped NASA manage the day-to-day spacecraft operations of the telescope, and provided preparation and training for the telescope’s many servicing missions. In this photo, technicians are performing a fit check of the solar arrays.
Backdropped by the horizon of Earth and the blackness of space, the Hubble Space Telescope (HST) floats gracefully after the release from Columbia’s robot arm at the conclusion of the very successful Servicing Mission 3B in March 2002. The event marked the fifth time that a space shuttle had set the great observatory into space. Those occasions were at its initial release in 1990, and at the conclusion of four subsequent servicing missions.

Deux grandes galaxies très brillantes et deux télescopes spatiaux se rejoignent sur cette image de la paire de galaxies VV 191, situées dans la constellation du Bouvier (Bootes), fusionnant la vue ultraviolette et visible de Hubble avec la vision infrarouge de Webb. Ce dernier permet de tracer la lumière émise par la galaxie elliptique brillante à gauche à travers la galaxie spirale à droite et d'étudier les effets de la poussière interstellaire dans cette dernière.
Avec Hubble à gauche, la galaxie elliptique est extrêmement brillante à son noyau circulaire, avec une lumière blanche plus faible s'étendant jusqu'à ses bords circulaires transparents. Avec Weeb à droites), la galaxie spirale brillante a également un noyau blanc brillant, mais des bras en spirale rouge et violet clair qui commencent au centre et tournent dans le sens des aiguilles d'une montre vers l'extérieur. Ils se terminent en rouge pâle et semblent chevaucher la galaxie elliptique de gauche. Tout au long de la scène, une gamme de galaxies lointaines, dont la majorité sont très petites et rouges, apparaissent sous forme de taches. En haut à gauche de la galaxie elliptique, deux spirales inégales ont des tailles apparentes similaires, mais apparaissent dans des couleurs très différentes.
Dans l'image de Hubble à gauche, au coeur de la galaxie elliptique, le faible arc rouge vers 10 heures est en fait une galaxie lointaine qui a subi une lentille gravitationnelle, sa gravité étant si grande qu'elle a étiré et magnifié l'apparence de la galaxie d'arrière-plan. Cette galaxie lointaine est également dupliquée sous la forme d'un petit point difficile à voir autour de 4 heures au centre de la galaxie elliptique. Dans l'image de Weeb de droite, cette galaxie lointaine est clairement révélée pour la première fois, étant si faible et non détectée dans les données de Hubble.
Les données dans le proche infrarouge de Webb nous montrent également les bras spiraux plus longs et extrêmement poussiéreux de la galaxie de manière beaucoup plus détaillée, donnant aux bras une apparence de chevauchement avec le renflement central de la galaxie elliptique blanche brillante sur la gauche. Bien que ces deux galaxies soient relativement proches astronomiquement parlant, elles n'interagissent pas activement (cf. NASA, ESA, CSA, STScI, R. Windhorst (Arizona State University), W. Keel (University of Alabama), S. Wyithe (University of Melbourne, Australia), and the JWST PEARLS Team).

The Hubble Space Telescope (HST)
Launched in 1990, the Hubble Space Telescope (HST) has revolutionized astronomy by providing unprecedented views of the Universe. Hubble's spectral range extends from the ultraviolet, through the visible, and into the near-infrared. NASA will fly a servicing mission in 2008 to bring two new science instruments to Hubble - the Cosmic Origins Spectrograph and the Wide Field Camera 3. New gyros and batteries will extend Hubble's life through 2013.

We live here on our little blue dot and don't really know much about the incredible things out there. Infinite wide, fantastic nebulae, supernovae, gigantic stars, neutron stars, black holes and quasars that beam their plasma light years into the distant rays of space that no human has ever seen before.
Hubble opened the door to a tiny slit for the first time, the Extremly Large Telescope of the ESO will open this slit further. Unfortunately it will only see the first light in 2024.
The Hubble Space Telescope (partially obscured), photographed from one of the Space Shuttle Columbia’s windows, begins its separation from the orbiter upon release from the Remote Manipulator System (RMS) robotic arm. The STS-109 crew deployed the telescope at 4:04 a.m. CST on March 9, 2002. Afterward, the seven crew members began to focus their attention on the trip home, scheduled for March 12. The STS-109 astronauts had conducted five spacewalks to service and upgrade Hubble.

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.

This image combines Hubble observations of M 106 with additional information captured by amateur astronomers Robert Gendler and Jay GaBany. Gendler combined Hubble data with his own observations to produce this stunning colour image. M 106 is a relatively nearby spiral galaxy, a little over 20 million light-years away.
This galaxy composite is NGC 4654, an intermediate spiral galaxy located 55 million light-years away in the constellation Virgo. The data comprising this view were acquired with the WFC3 instrument on Hubble in December 2019.
This striking cosmic whirl is the centre of galaxy NGC 524, as seen with the NASA/ESA Hubble Space Telescope. This galaxy is located in the constellation of Pisces, some 90 million light-years from Earth. NGC 524 is a lenticular galaxy. Lenticular galaxies are believed to be an intermediate state in galactic evolution — they are neither elliptical nor spiral. Spirals are middle-aged galaxies with vast, pinwheeling arms that contain millions of stars. Along with these stars are large clouds of gas and dust that, when dense enough, are the nurseries where new stars are born. When all the gas is either depleted or lost into space, the arms gradually fade away and the spiral shape begins to weaken. At the end of this process, what remains is a lenticular galaxy — a bright disc full of old, red stars surrounded by what little gas and dust the galaxy has managed to cling on to. This image shows the shape of NGC 524 in detail, formed by the remaining gas surrounding the galaxy’s central bulge. Observations of this galaxy have revealed that it maintains some spiral-like motion, explaining its intricate structure. A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Judy Schmidt.
A 310 millions d'années-lumière de la Terre, dans la constellation de l'Hydre femelle (Hydra), Hickson Compact Group 40 (HCG 40) comprend trois galaxies en forme de spirale, une galaxie elliptique et une galaxie lenticulaire (en forme de lentille). Ces différentes galaxies se sont croisées au cours de leur évolution pour créer un échantillon de galaxies exceptionnellement peuplé et éclectique. Ces galaxies interagissent gravitationnellement en raison de la présence de beaucoup de gaz chauds. Dans environ un milliard d’années, elles finiront par entrer en collision et fusionner pour former une galaxie elliptique géante.
Sur la centaine de groupes de galaxies compactes de ce type qui ont été cataloguées à ce jour, le plus connu est le Quintette de Stephan HCG 92, à 270 millions d'années-lumière de la Terre dans la constellation de Pégase (Pegasus). Le sextette de Seyfert HCG 79, dans la constellation de la tête du Serpent (Serpens Caput) à 200 millions d'années-lumière de la Terre, ne contient en fait que cinq galaxies en interaction (cf. NASA, ESA, STScI, traitement de l'image : Alyssa Pagan STScI).

Globular clusters are relatively common in our sky, and generally look similar. However, this image, taken using the NASA/ESA Hubble Space Telescope, shows a unique example of such a cluster — Palomar 2. Palomar 2 is part of a group of 15 globulars known as the Palomar clusters. These clusters, as the name suggests, were discovered in survey plates from the first Palomar Observatory Sky Survey in the 1950s, a project that involved some of the most well-known astronomers of the day, including Edwin Hubble. They were discovered quite late because they are so faint — each is either extremely remote, very heavily hidden behind blankets of dust, or has a very small number of remaining stars. This particular cluster is unique in more than one way. For one, it is the only globular cluster that we see in this part of the sky, the northern constellation of Auriga (The Charioteer). Globular clusters orbit the centre of a galaxy like the Milky Way in the same way that satellites circle around the Earth. This means that they normally lie closer in to the galactic centre than we do, and so we almost always see them in the same region of the sky. Palomar 2 is an exception to this, as it is around five times further away from the centre of the Milky Way than other clusters. It also lies in the opposite direction — further out than Earth — and so it is classed as an “outer halo” globular. It is also unusual due to its brightness. The cluster is veiled by a mask of dust, dampening the apparent brightness of the stars within it and making it appear as a very faint burst of stars. The stunning NASA/ESA Hubble Space Telescope image above shows Palomar 2 in a way that could not be captured from smaller or ground-based telescopes — some amateur astronomers with large telescopes attempt to observe all of the obscure and well-hidden Palomar 15 as a challenge, to see how many they can pick out from the starry sky.

This NASA/ESA HUbble Space Telescope image shows galaxy NGC 6503. The galaxy, which lies 30 000 light-years away is at the edge of a strangely empty patch of space called the Local Void. This new image shows a very rich set of colours, adding to the detail seen in previous images.
NGC 6217 is a Barred Spiral Galaxy in the constellation Ursa Minor and lies 60 million light-years away.

Here's a view of the Homunculus Nebula, the result of a massive ejection of material in the form of two lobes with a central skirt from the star system Eta Carinae, located 7500 light-years away. This is a composite of Hubble WFC3 images acquired July 25, 2018 (PI Nathan Smith).
This "frozen explosion" is the result of what's called a near-supernova or supernova impostor, where the progenitor star survives the outburst of material. The event occurred (for us) in the 1840s, when for a while Eta Carinae became the 2nd brightest star in the sky.
The entire structure as we see it today is a little over half a light-year wide and about a light-year long.
Looking westward, one of the STS-109 crew members photographed the newly serviced and upgraded Hubble Space Telescope (HST) as it neared the earth's limb in March 2002. The Space Shuttle Columbia was located over the Atlantic Ocean southwest of the Cape Verde Islands when this image was taken. Low to mid-altitude clouds are visible across the picture. Some thunderstorms can be seen near the left center of the frame as the Sun reflects off the higher cloud tops.

This colour image shows the Hubble Ultra Deep Field region, a tiny but much-studied region in the constellation of Fornax, as observed with the MUSE instrument on ESO’s Very Large Telescope. But this picture only gives a very partial view of the riches of the MUSE data, which also provide a spectrum for each pixel in the picture. This data set has allowed astronomers not only to measure distances for far more of these galaxies than before — a total of 1600 — but also to find out much more about each of them. Surprisingly 72 new galaxies were found that had eluded deep imaging with the NASA/ESA Hubble Space Telescope.

The NASA/ESA Hubble Space Telescope doesn’t usually get much assistance from its celestial subjects — but to take this image, the telescope opted for teamwork and made good use of a fascinating cosmic phenomenon known as gravitational lensing.

Payload Officer Heinz Ansbacher, of Lepzig, Zuritania, deploys a high-power photorecon satellite somewhere over Zhenia. The RASA Medium Cargo Shuttle Constitution and its sister ships were built to quickly and cheaply haul compact satellites to orbit, closing The Sat Gap with the YSSR and building strategic networks of surveillance, communication, and navigation satellites with minimal expenditure. Using economies of scale and a mostly-reusable launch system, RASA is reducing its per-satellite costs with every launch, Not bad for 1989.
Each cargo mission lasts approximately 36 hours. The pilot and payload officer launch from the Cape Hennessy spaceport in the morning, conduct diagnostics and tests, and deploy their payload with an EVA. Their primary mission complete, they enjoy a freeze-dried dinner and go to sleep taped to the walls and ceiling. The next day, they conduct any additional assigned research RASA asks for, before reentering the atmosphere and landing in Brohemia in time for dinner.
The versatile, workhorse spacecraft can also carry research payloads, laying the groundwork for future technologies through careful preparation. By removing the bulky crew ejection seats (less necessary, now that the spacecraft has achieved a 99% predicted safety record) and pressurizing the cargo bay before takeoff, supplies can be packed to provide a two-week mission duration. This allows the two crew members to run longer science experiments, testing the limits of human spaceflight in low Erf orbit.

The Majestic Sombrero Galaxy, M104
NASA's Hubble Space Telescope has trained its razor-sharp eye on one of the universe's most stately and photogenic galaxies, the Sombrero galaxy, Messier 104 (M104). The galaxy's hallmark is a brilliant white, bulbous core encircled by the thick dust lanes comprising the spiral structure of the galaxy. As seen from Earth, the galaxy is tilted nearly edge-on. We view it from just six degrees north of its equatorial plane. This brilliant galaxy was named the Sombrero because of its resemblance to the broad rim and high-topped Mexican hat.
At a relatively bright magnitude of +8, M104 is just beyond the limit of naked-eye visibility and is easily seen through small telescopes. The Sombrero lies at the southern edge of the rich Virgo cluster of galaxies and is one of the most massive objects in that group, equivalent to 800 billion suns. The galaxy is 50,000 light-years across and is located 28 million light-years from Earth.
Hubble easily resolves M104's rich system of globular clusters, estimated to be nearly 2,000 in number — 10 times as many as orbit our Milky Way galaxy. The ages of the clusters are similar to the clusters in the Milky Way, ranging from 10-13 billion years old. Embedded in the bright core of M104 is a smaller disk, which is tilted relative to the large disk. X-ray emission suggests that there is material falling into the compact core, where a 1-billion-solar-mass black hole resides.
In the 19th century, some astronomers speculated that M104 was simply an edge-on disk of luminous gas surrounding a young star, which is prototypical of the genesis of our solar system. But in 1912, astronomer V. M. Slipher discovered that the hat-like object appeared to be rushing away from us at 700 miles per second. This enormous velocity offered some of the earliest clues that the Sombrero was really another galaxy, and that the universe was expanding in all directions.
The Hubble Heritage Team took these observations in May-June 2003 with the space telescope's Advanced Camera for Surveys. Images were taken in three filters (red, green, and blue) to yield a natural-color image. The team took six pictures of the galaxy and then stitched them together to create the final composite image. One of the largest Hubble mosaics ever assembled, this magnificent galaxy has an apparent diameter that is nearly one-fifth the diameter of the full moon.

The fabulous images released by NASA of distant galaxies and nebulas captured by the Webb Telescope reminded me that we have our own version of the Hubble Telescope - made in Legos of course!
Surprisingly, the newer Webb telescope does not replace the 32-year old Hubble, but supplements its capabilities.

La galaxie spirale NGC 2276 se situe à 120 millions d’années-lumière de la Terre, dans la constellation septentrionale de Céphée (Cepheus) et semble un peu déséquilibrée avec un centre brillant d’étoiles jaunâtres plus anciennes, son renflement semblant décalé vers le coin supérieur gauche.
En réalité, une galaxie elliptique voisine NGC 2300 (à droite de NGC 2276, mais non vue ici) tire gravitationnellement sur son disque d'étoiles bleues, d'un côté vers l'extérieur, déformant l'apparence normale d' "œuf au plat" de la galaxie (le renflement central d’étoiles vieillissantes ressemblant au "jaune d’œuf," entouré d’un disque d’étoiles constituant le "blanc d’œuf").
Des étoiles massives, nouvellement nées et de courte durée, forment un bras bleu brillant le long de son bord supérieur gauche et tracent une voie de formation d'étoiles intense (cf. NASA, ESA, STScI, Paul Sell Université de Floride).
