I struggled with the colors but I think this image turned out quite good 😶‍🌫️ 🔭 This is Saturn as seen by Hubble yesterday, and processed by me! While I am pretty sure the moon in the top left corner is Titan, I have no idea about the ones in the top right corner...

Saturn seen in visible light by the Hubble Space Telescope. The planet itself is yellow-orange-ish with bright rings around it. Near the top left corner a huge moon, Titan, can be seen as a globe near the planet. In the top right corner, three small bright dots can be spotted. They also are Saturn's moons.

Today was a great day for me on professional and personal levels, so I will share something even greater: a JWST observation of the centre of our galaxy! 🔭 This is Sagittarius B2, a molecular cloud a few hundreds light years away from SgrA*, as seen by MIRI and processed by me!

Observation of the Sgr B2 molecular cloud in mid-infrared by the JWST. The cloud appears mostly in red/orange and blue colors. In this wavelength, what is mostly appearing is the dust in the cloud, which is everywhere in the image. Some brighter spots can be seen, where new stars are located. Background and foreground stars can also be spotted as blue and bright dots.

Thank you for this message! I'd be really interested, at some point, in conducting a historical study of the exploration of the outer Solar system's worlds. I am sure that so many scientific, political, and social stories could be covered through that angle!

Thomas Carpentier @thocarp.bsky.social · 02/09/2026

It is a bit exaggerated as I wanted to have them in white and not in yellow-ish colour (the result of the addition of the green and red filters where the clouds are more visible). Here you can see the clouds in those two pre-processed filters (F765M and F845M)

Je suis probablement biaisé par toutes les images de Neptune qu'on a l'habitude de voir avec ce bleu foncé aussi, d'où le fait que j'ai trouvé ce résultat plus satisfaisant que d'autres...

Thomas Carpentier @thocarp.bsky.social · 02/09/2026

Le filtre à plus petite longueur d'onde que j'ai utilisé pour le bleu ici (F467M) a vraiment pris le dessus sur les deux autres, d'où ce bleu plutôt foncé proche des images de Voyager. En essayant d'avoir un bleu moins foncé l'image me paraissait moins bien...

That's the first time that I am happy with my processed image of an observation of Neptune by Hubble, so I am sharing it here too! 🔭 This observation was done yesterday around 6pm UTC. The data come from the 17964 proposal led by Mariarosa Marinelli.

By the way, what pains me the most about processing JWST data is that I will never be able to produce a good image of the Crab Nebula using NIRCam and MIRI data... I tried multiple times but I never got the filters alignment right, and the noise on MIRI's filters is difficult to manage

Thomas Carpentier @thocarp.bsky.social · 29/08/2026

While I was at it, I gave another try to the observation of the Cassiopeia A remnant! It is still one of my favorite JWST observation since the beginning of the mission (I have a soft spot in my heart for supernovae..) 🔭

Observation in near-infrared of the remnant of another supernova, Cassiopeia A, which alledgedly happened in the 17th century. It also looks like an expanding bubble with much more detailed filaments in a lot of colours: from orange to violet. Dozens of stars can be seen in the background as well.

Thomas Carpentier @thocarp.bsky.social · 29/08/2026

Here's my go at the JWST's observation of the Kepler supernova! 🔭 The noise was difficult to deal with while not losing too much faint details of the remnant, but I think I've managed to produce a satisfying result. HD & credits: flic.kr/p/2sxV8Vi

Observation in mid-infrared of the remnant of a supernova, a massive star that exploded. This supernova was seen from Earth in 1604. The image itself is looking like an expanding orange bubble with filaments going in various directions. The background is full of small blue dots: stars and galaxies!

#NASAWebb imaged the Lion Nebula in near- and mid-infrared light just in time for #WorldLionDay. The stellar core, looking like the lion’s “nose,” is responsible for sculpting the nebula’s complex gas and dust structures: news.stsci.edu/4x639kM

$Planetary nebula NGC 2392, the Lion Nebula, against the black background of space. The nebula is at center, circular in shape, and looks like a male lion’s head. In the very center is a small, pinkish-white circle with eight-point diffraction spikes, a white dwarf star. Surrounding the star are light purple-pink cavernous bubbles and shell-like rings. The bubbles and shells collectively form an oval with two small, wide arcs near the top, reminiscent of a lion’s face and its ears. What appears to be extended outward from the lion’s face is a thick ring of purple-blue material. The width of the ring is consistent throughout and resembles a mane. The area closest to the lion’s face looks cloudy, while the edges of the mane look like there are clumps of dust with comet-like tails and strands. In the background are distant galaxies and stars. Some galaxies appear as yellow and orange points of light and others with visible spiral structures. A couple of the stars have diffraction spikes.$

I processed this observation using the data obtained through the 5408 proposal, led by Dr. Megan Reiter (www.stsci.edu/jwst-program...) Here are other images that I processed using data from that program:

HH-901 seen by the JWST. It looks like some thin orange pillars emerging from a denser gas cloud formation. Hundreds of stars can be spotted in the background.

HH-666 seen by the JWST. The gas formation looks like a orange dragon with its head pointing to the right hand side of the image. Hundreds of stars can be seen in the background

HH-903 seen by the JWST. A compact gas cloud on the left from what emerges like a long finger where new stars are being born. Dozens of stars can be seen in the background.

HH-900 seen by the JWST. It looks like a orange mountain range emerging from the bottom part of the image. On the right hand side of the image is located a red gas cloud formation looking like an oval bubble.

The JWST will never cease to amaze me... 🔭 This is the HH-1019 region, in the Orion Nebula, and everything here is incredible! I suspect there even is a planetary nebula on this image, which looks amazing! (It really looks like NGC-6072 to me) HD: flic.kr/p/2sqVKuS

HH-1019 seen by the JWST/NIRCam. A huge orange gas cloud formation can be seen on the left part of the image, from where some smaller gas cloud are "ejected". Some objects looking like blobs can also be spotted: small gas cloud chunk from where stars are born! In the bottom middle part of the image, a planetary nebula can be seen: the remnant of a small/medium size star that died and slowly ejecting its outer layers.

It has been a long time since I posted new pictures (who would've thought that doing a PhD was that time-consuming??), but here are two JWST pictures of Centaurus A! 🔭 A NIRCam picture of the full galaxy (you probably have seen the press release yesterday!), and a focus on the nucleus by MIRI

A vertical view of a lenticular or elliptical galaxy by the JWST in near-infrared wavelength. The gas structures are seen in red and orange colours, stretching from the top of the image to the bottom. In the middle lies the centre of the galaxy, looking really bright as this galaxy hosts an active galactical nucleus. Many nebulae of the galaxy can be spotted here and there, with stars in the galaxy appearing like small dots.

The centre of that same galaxy in mid-infrared wavelength as seen by the JWST. The gas in the galaxy appears like a fluffy ensemble in orange and yellow-ish colours. The AGN is appearing as bright as in the other picture.

No less than 60 million stars in one image. It's possible thanks to ESA's Euclid mission. For just one day, Euclid turned its gaze to the crowded heart of the Milky Way and captured the largest, most detailed photo ever taken of our galaxy's centre in visible light. Let's dive deeper 👇 🔭 🧪 ☄️ 1/8

A dense field of tiny stars fills this square image taken by the European Space Agency’s Euclid space telescope. The lower and central areas are dominated by bright yellow and gold colours, forming a textured background similar to fine glitter or sand. Dark brown and black patches cut irregularly through the yellow regions, like ink stains or clouds of smoke. Toward the upper left, the colours shift to purple and reddish tones, blending gently into the surrounding star field. Small blue points of light are scattered across the image.

STScI scientists using the Euclid space telescope made a discovery that provides clues to what’s happening deep within some stars’ interiors: news.stsci.edu/49x77d1 🔭

$This astronomical image is speckled with thousands of stars against the black background of space. Most stars are visible only as white pinpoints. The great majority of stars are crowding the center, which appears as an irregular round shape. Most stars in the center of this cluster are whiter, and those along periphery edges yellower. The stars across the entire image range in color from blue to white to yellowish red. A few of the stars appear a bit larger and brighter than the rest, with six diffraction spikes.$

Dear Lord Vallance,

Cuts to funding for astronomy and space science

We are writing to you as physics teachers in secondary schools and sixth form colleges, to express our grave concern at the cuts to funding for astronomy and space science, and particle and nuclear physics, proposed by the Science and Technology Facilities Council (STFC).

As you know, these amount to 30% overall, and project groups have been asked to plan for budget reductions of up to 60%. We urge you to take prompt action to reverse these cuts, the scale of which are without precedent in modern times.
