Fuck Trump. Fuck the puppeteers behind him. Fuck the GOP, especially congressional Republicans and quisling Democrats, who enabled him. Fuck the people who voted for this, and fuck the media for never reporting on him realistically.
Fuck them all, for they have truly fucked us and the world.
The slow death of a star seen in infrared. The star is ejecting its outer layers at a slow pace, creating what looks like an expecting bubble of gas. The material ejected by the star is appearing as orange/red here, looking like a skull (hence its name). Dozens of stars in our galaxy and background galaxies can be spotted everywhere around it (and even behind it!).
The same planetary nebula seen in mid-infrared. The skull and the bubble are still clearly visible.
I was waiting all day for the data release of those observations, I am clearly not disappointed!🔭
This is the Cranium Nebula, a planetary nebula, as seen by the JWST with NIRCam (l) and MIRI (r). Processing this data was so fun, this plan. nebula is incredible!

This image has been processed using data obtained through the 4548 proposal led by Dr. Mark McCaughrean.
You can even find his own version here: bsky.app/profile/mark...
Hey Mark! The credits are all put on the Flickr description of the image, with a direct link to the proposal as well
If you prefer, I can also do the same here with a response post to my previous one!
Go read about star & planet formation on the shiny new website of The Star Formation Newsletter! It's back! 🎉

Première planète imagée grâce au coronographe français du JWST
Découverte de TWA 7b, une jeune planète de masse comparable à Saturne, dix fois moins massive que les exoplanètes déjà imagées. Une première mondiale.

Two jets, appearing red and violet, being ejected by a central protostar, hidden behind gas. The jets are extending to the left and right parts of the image. Two perpendicular thinner jets can be seen as well, coming from another protostar. Hundreds of stars can be seen in the background of the image, appearing like bright dots with the JWST trademark diffraction spikes.
This is one of my favorite JWST observation ever! 🔭 💙
This is HH288, a star heavier than the Sun being born in front of our eyes! The jets are the result of that process. There is even another star being born near it, as the perpendicular jets are showing.

Clearly not as impressive as the images of Northern Europe, but still impressive to catch auroras in Fiesole/Florence, Italy 🔭 🥰
My very first auroras in 28 years, I'm really moved right now 🥺
The centre part of a spiral galaxy where the middle is extremely bright, where the supermassive black hole is located. The middle is surrounded by rings of gas, appearing in darker coulours (mostly red and orange). Some blue gas part can be seen drifting away from the middle as the galaxy is ejecting waves of gas because of its activity.
It has been a long time since I posted a picture here, so here's one to make it up! 🔭
This is the PGC 50779 galaxy, also known as the Circinus Galaxy, located some 13 million light-years away from us.

The observation was made during the night, and just like with NIRCam, the fragments and the tail are beautiful!

An infrared observation of a comet, C/2025 K1, seen by the JWST. On the left, the main part of the comet, seen as a bright dot, and its coma. On the right, two small dots which are fragments of the comet.
I am not really good with this kind of observation, but here's my processed version of the JWST observation of the C/2025 K1 comet, which was made today! 🔭
The multiple fragments are clearly visible there, in full beauty

One more shot of today's Etna eruption.
Multispectral image taken by Sentinel-2.
A gas cloud seen in infrared light. Near the upper-centre part of the image, a pillar-like structure, just like a finger, can be seen, with a young star at the tip of it. The gas composing the cloud appears in red and orange colours. From top left to top right, a veil of gas can also be spotted, in beige and red colours. It is in the background of that cloud. Dozens of stars cna be spotted as well, with a big one on the centre-bottom part, carving around it the gas cloud thanks to its stellars winds.
Here's to celebrate the end of my first term as a PhD Researcher! 🔭 🎉
This is the Pismis 24 star cluster as seen by the JWST, processed by me! It is located some 6,500 light years away, and it's part of the NGC-6357 nebula.

In this JWST image, Saturn appears as a pale gold/brownish sphere with horizontal bands, encircled by a bright whithish, thin oval ring system. The atmosphere is showing off a few circle whithish storm-like features. On the top left also its world Titan is visible as a gold glowing sphere.

Physics in action: a truly mesmerising #SolarFlare on the Sun last night, from the same region that produced strong flares and triggered widespread aurora back in mid-November. The flare gives a hypnotic example of how plasma and magnetic fields interact in the Sun’s atmosphere.

A spiral galaxy seen in visible light. The centre is extremely bright, while the arms appear in red and orange. Inside the arms some blue areas can be spotted. These areas are clusters of stars! On the left part of the image, a part of one of the arms appears like going up.
Putting a spiral galaxy in your TL just for the sake of it! 🔭
This is the NGC-4569/M90 galaxy as seen by Hubble and processed by me. It is located some 60M light years away from us!

Look what arrived today! 👀 🔭
This is the October 2025 issue of "Reflets de la Physique" with an image that I processed on its cover, and the book "Onbegrensd Universum" written by @govertschilling.nl with two images of mine inside! 😎
A large portion of a gas cloud seen in infrared light. Most of the cloud appears in red, orange and yellow colours. Some sort of cavities can be seen in the cloud, being brighter and in blue: this is where large stars being born have pushed away the gas around them. Hundreds of small dots can be spotted everywhere, being stars in the LMC galaxy around and in the observed region.
A stellar nursery at its finest! 🔭
This is LHA120-N159 region in the LMC as seen by the JWST one year ago. It is home to MANY new born stars and many more to come!
I was in awe with how beautiful this region is while I was processing these data earlier this morning!

November 18, 2025 - Longueuil Quebec Today, at the SpaceBound 2025 Conference, the Honourable Mélanie Joly Minister of Industry and Minister responsible for Canada Economic Development for Quebec Regions, made he historic announcement that Canada will increase its investment to Europear Space Agency (ESA) programs by $528.5 million. This investment represents a tenfold increase compared to previous contributions and is set ta advance research and development of Canadian-made space technologies for poth civilian and defence purposes. It wil help build an industrial base that is ready and capable of supporting Canada's tommercial, defence and security needs.
A few days before ESA's Ministerial, this is really huge! 🔭
In 2023, Canada's budget for ESA was €34M for instance.

Well, here's some very exciting news!
I've been wanting to share this for a few months, but had to wait for the pre-print to drop.
A NEW GLITCH ON A MILLISECOND PULSAR HAS BEEN OBSERVED!
These events are extremely rare - only two others since MSPs discovered.

A really nice book by the way! I bought it at the shop in the Galileo Museum in Firenze, and I really don't regret that purchase 👏

A nebula that contains stars and protostars. To the right of center, there is a bright white point made up of two orbiting stars with a four-pronged diffraction pattern. At 2 o’clock from this star, there is another, smaller bright light, a protostar, surrounded by a dark, edge-on disk of matter, which appears as a vertical line. In the center of the image is a cavity where the clouds are thinner and background stars shine through. The stars and protostar are on the edges of this cavity and are surrounded by dark clouds that appear like thick smoke in the light. A thin, short blue jet of material extends roughly horizontally, emerging from both sides of the disk. The jet is interrupted by the cavity and then continues to the left, cutting through the center of the frame.
The brightest point in this Hubble image of FS Tau is a binary system, consisting of two stars orbiting each other, that have cleared much of its surrounding dust and gas away.

Rosetta’s lander Philae is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first two CIVA images confirm. One of the lander’s three feet can be seen in the foreground. The image is a two-image mosaic (pic: ESA/Rosetta/Philae/CIVA)
#OTD: 12 November 2014, @esa.int's Rosetta Philae lander made history by touching down on the surface of a comet, the first spacecraft ever to do so. The landing was confirmed at 16:03 GMT/17:03 CET 🧪🔭
