Here's a picture of my friend's dog yo cheer you up! She really loves space science in her own way too
And my friend called her Cassiopeia, because she loves that constellation, she is a space dog through-and-through!
I processed this image using data obtained through the 4547 JWST program, led by @markmccaughrean.bsky.social 🔭
www.stsci.edu/jwst-program...
A gigantic gas cloud seen in infrared spreading across the entire image. The gas appears mostly in orange, although a blue-ish veil can be spotted in the area where new born stars pushed the gas away. Hundreds of stars can be spotted as well, mostly appearing in blue. On the top-left corner, a huge star can be seen with gas probably being pushed away.
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.

Will do 🫡
Red patches of gas looking like jellyfishes seen in infrared light. A red and grey veil of gas can also be spotted in the entire image. The background is full of stars and galaxies.
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!

And I love Euclid's data! (even though the noise is difficult to fix...)
Oooh can't wait to see that then!
The black and white image of the Euclid/VIS data.
The black and white image of the JWST/MIRI data.
Here are the two black and white images that I used: the first is the Euclid/VIS one, the second is the JWST/MIRI one. 🔭
That planetary nebula is so incredible in every wavelength 💙
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.
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!

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 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.

I can send it to you! Where do you prefer me to do it?
And now the MIRI version! 🔭
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.
