How to describe this with words?.. 🔭 This is the W51A region, some 17,000 light years away from us, as seen by the JWST/NIRCam. I loved every second that I spent processing this image, and I think you can clearly see why! HD & credits: flic.kr/p/2sbFB4i

Bona Diada de Sant Jordi a tothom! 🌹🐉 This is the best tradition in my own opinion: people gifting themselves roses and books, so much beauty into that! So here's my own-processed gift: a cosmic rose seen by Hubble, the well known Arp 273 merger! 🔭

My processed image of the JWST observation of Sharpless 305, a star-forming region inside our Milky Way! 🔭 This emission nebula is located ~14,000 light-years away, with several dozens of Young Stellar Objects (YSOs) having been discovered inside this nebula. HD: flic.kr/p/2s5qkHF

I welcome you to the heart of the Carina Nebula! 🔭 These are the HH1159-HH1164 protostars inside the Carina Nebula as seen by the JWST, using data obtained through the 5408 program led by Dr. Megan Reiter. These patches look like cosmic jellyfishes if you ask me! HD: flic.kr/p/2s3ieDg

TODAY. Take Back our Science Rally. Don't take this administration's assault on science sitting down. Get to a rally: fight2win.standupforscience.... #StandUpForScience #March7 #Rally #science #savescience

Seeing this beautiful picture reminded me of an earlier JWST observation of the same nebula, during its calibration days in 2022. So I went on to combine the Euclid's VIS data with this single MIRI filter (F560W) to create this image! 🔭

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.

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! HD: flic.kr/p/2rYiLSJ

we need to talk about that Ring Super Bowl ad

😎 This weekend, ESA marks 18 years of Europe’s Columbus laboratory in orbit, and we’ve got a couple of these epic ‘How Columbus Learnt to Fly’ books to give away! Just share this post for a chance to win!👍

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. HD: flic.kr/p/2rUKqvx

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 🥺

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. HD: flic.kr/p/2rS7tjZ

And now the MIRI version! 🔭 The observation was made during the night, and just like with NIRCam, the fragments and the tail are beautiful! HD: flic.kr/p/2rPp5EV

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 HD: flic.kr/p/2rPhQUz

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.

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! HD: flic.kr/p/2rJqjVV

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 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! HD: flic.kr/p/2rGG32u

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 JWST wonder, once again! 🔭 This is the image of the NGC-2440 planetary nebula as seen by the JWST one year ago, that I processed last night! Look how wonderful that thing is 😍 And if you zoom on the centre, you can see a little dot which is suspect is the white dwarf! HD: flic.kr/p/2rCzjR1

Today in PASA we published a new image of our Milky Way at low radio frequencies, in unprecedented colour and detail. Here's just a tiny piece of it -- the whole thing is ten times bigger! We're seeing high energy electrons whirl around cosmic magnetic fields from exploded stars, and more!

Achievement of the day: one of my images on the cover of a French journal, "Les Reflets de la Physique" 😎 🔭 A big thank you to @oliberne.bsky.social who made it possible!

The violent beauty of stars being born in full display thanks to the JWST! 🔭 This is the region around the HOPS-108 protostar in the Orion Nebula. There are so many beautiful jets produced by baby stars tantrum 🤩 HD: flic.kr/p/2rAgnuW

Welcome to Westerhout 3 (or W3) as seen by the JWST! 🔭 This is just a small part of the giant molecular cloud, which is itself located 6,000 light years away from us. It is actively producing new massive stars at a high rate! HD: flic.kr/p/2rz8d85

Last night, the JWST observed Uranus for calibration. Even like that the result is awesome, so here you go with my processed image of that observation! 🔭 HD: flic.kr/p/2ry78y3

The best part of processing space telescopes' data is to discover new regions that I didn't even know existed in the first place! 🔭 This is G054.093+01.748, a star forming region in our galaxy, as seen by the JWST recently, located in the Outer Scutum–Centaurus spiral arm. HD: flic.kr/p/2rxLQyT

Dr. Jane Goodall filmed an interview with Netflix in March 2025 that she understood would only be released after her death.

I am bringing your TL some sparkles! 🔭 ✨ This is the NGC-1850 star cluster in the LMC, as seen by Hubble! The number of stars in that part of the cluster is bonkers 🤯 Processing that data was really fun! HD: flic.kr/p/2ruwYSH

The JWST had a new look into the IC348 star forming region last year, and here's my processed image of that observation! 🔭 IC348 is located some 1,000 light years away from us and is made of hundreds of new stars born there. HD: flic.kr/p/2ruCvCz

Here are some things that Charlie Kirk said in his life. The man is dead, and so it only seems fair to share his legacy by cataloguing the values he spread while alive.
