Reposting to correct an error: trump admin is quietly gutting 13 buildings and about 100 laboratories at Goddard campus that has been instrumental to Hubble and James Webb telescope missions. Staff say they’ve be locked and told to move equipment. Anything left behind will be thrown away.

We are releasing seven new science publications today, based on our Q1 data release earlier this year. All revolve around galaxies, from dust to interactions to active centers.These are accompanied by two new image collages drawn from the same release. 1/ 🔭 #astronomy #space #ESA

Recently I started to learn how to obtain and process data from Herschel, a former ESA space telescope (2009-13). Here's an image from one observation of that telescope! 🔭 This is the Eagle Nebula seen in infrared, and if you zoom in: the Pillars of Creation are there! HD: flic.kr/p/2rD4JDu

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.

There were so many people in the streets in Florence this morning, it was amazing! 🇵🇸✊ Firenze lo sa da quale parte stare!

All eyes on #3I/ATLAS ☄️ Our Mars Express & ExoMars Trace Gas Orbiter will observe the comet around its closest approach to Mars on 3 October 2025, when 3I/ATLAS will be around 30 million km from the red planet. Stay tuned and follow esa.int/3IATLAS 🔭🧪

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.

Astronomers spot mysterious gamma-ray explosion, unlike any detected before! 💥 Our VLT revealed that its source lies outside our galaxy. Yet its cause is still unknown 🤔 Read more: https://www.eso.org/public/news/eso2514/ 🔭 🧪 ☄️ #extragalactic #highenergyastro

For 58€ a month I can ride on almost any public transport anywhere in Germany. Within a 15 minute walk from my house I can access 4 S Bahn lines, 3 UBahn lines, regional trains (I honestly don’t even know how many of those), 3 tram lines and at least 4 city bus lines (probably more).

This is a big one! 🔭 A few weeks ago, I worked with a team of astronomers, led by Anne-Marie Lagrange, on SPHERE and MIRI data. It was about the TWA7 exoplanet, something you probably read about in June. They asked me to produce another image, so here's the result:

Starting next Monday and for the next 4 years, I will be a PhD Researcher at the EUI in Florence! As I arrived yesterday, I decided to visit, for the first time, the historic centre of Florence, and it's just incredible!! I can't wait to see even more

I have arachnophobia, but when it's the JWST that observes a spider, I am not scared: I am in awe! 🔭 This is the Red Spider Nebula, a planetary nebula located ~5,000 light years away, as seen by the JWST last year! Every dot here is a star in a small part of our own galaxy HD: flic.kr/p/2robFBx

87M light years away from us lies this lenticular galaxy, NGC-1482. Here you can its beauty thanks to JWST/MIRI data released earlier today! 🔭 It is a starburst galaxy as well, meaning a lot of new stars are born there every years, way more than in our own Milky Way! HD: flic.kr/p/2rnj5cs

Yesterday I was in Barcelona for the day, and that city is really the love of my life 🥰 There are so many beautiful things to see and do rather than just going to tourists-invaded spots (such as the Barceloneta playa)

43°C today in Toulouse, 41°C tomorrow and Wednesday, probably another heat wave from Saturday on. It'll be incredibly hard to not be exhausted, both physically and mentally... I love summer, but this is not it. This is what we all fear, except those who hold the power.

Six months ago, Hubble took a deep look into what is known as Dracula's Chivito. Here is the visible image I processed of it! 🔭 This is a protoplanetary disk at an estimated distance of ~980 light years. A young star is born inside of that disk, and maybe some planets too! HD: flic.kr/p/2rmvts8

Actually heartbreaking, the list of colleagues that have run the show behind the scenes for so many years who are saying their pre-emptive goodbyes and taking literally thousands of years of amassed knowledge and expertise with them. Not to mention camaraderie and community. Morale is ... bleak.

Cats and JWST are two of my favourite things ever; mixing them is even more gracious! 🔭 This is the Cat's Paw Nebula as seen by the JWST! I finally got enough time to process the recent data of that observation, and I loved every minute of that processing! ❤️ HD: flic.kr/p/2rjJXkv

And here's the same galaxy but this time as seen by the JWST! 🔭 In infrared light its spiral form is even more beautiful if you ask me! Excuse the cross, two of the three filters came with it... The data was released earlier today. HD: flic.kr/p/2rjFQek

It's been a long time since I posted an image, so here's a nice one to make it up! 🔭 This is the NGC-5168 galaxy, located ~83M light years away. It was observed in 2018 to help astronomers learn more about the expansion of the Universe! HD: flic.kr/p/2rjxTKJ

I won't be posting any image today, but today was full of great news for me that I will be able to share with you sooner or later! One of them will be an image that I am particularly proud of; the other will have to wait some months though 🤫

One year ago, the JWST took a look at a peculiar galaxy: NGC-5253! 🔭 It is an irregular dwarf galaxy, the nearest blue compact dwarf at ~11M light years. It is also a starburst galaxy, with a production of new stars way higher than the Milky Way! HD: flic.kr/p/2rh5Uma

Our solar system has a new dwarf planet/very very distant asteroid!

And here's another one from the same proposal! 🔭 This one is NGC-4388, some 57M light years away. It is a spiral galaxy that we are seeing edge-on. Observing it in infrared shows how its galactic nucleus is active! And look at these beautiful background spiral galaxies 🥰 HD: flic.kr/p/2rg7AYD

I meant to share this JWST image earlier, but I forgot to post... Better late than never I guess! 🔭 This is the NGC-4666 galaxy, located ~55M light years away. It is not visible here, but it is interacting with two other galaxies (a spiral and a dwarf). HD: flic.kr/p/2rgdy22

Celebrate 3️⃣ years of science with Webb! 🥳 To mark the occasion, the NASA/ESA/CSA space telescope set its sights on the wondrous Cat’s Paw Nebula 🐈 Studying such stellar nurseries helps us understand how cloud turns to stars ✨ Read more 👉 www.esa.int/Science_Expl... 🔭 🧪

Let's take a look in our neighbor's backyard! 🔭 This is a small part of the 30 Dor region in the Large Magellanic Cloud some ~160 000 light years away. It was observed by the JWST back in early July 2023, a few days before the release of the first official JWST images. HD: flic.kr/p/2rfboEZ

A cosmic cocoon! 🔭 This is the NGC-4490 and NGC-4485 couple, or Arp 269. NGC-4490 is known as the Cocoon Galaxy. It is a starburst galaxy, meaning that a lot of new stars are born every year there, hence the magenta areas in the image: nebulae where they are born! HD: flic.kr/p/2rexrEg

💥💥 Double detonation!  For the first time, astronomers have obtained visual evidence that a star met its end by detonating twice. The fingerprint that points to this mechanism is represented by two separate shells of calcium.   Read more: https://www.eso.org/public/news/eso2511/ 🔭 🧪 ☄️ 1/

I fell in love with that galaxy while processing data from its observation by Hubble! 🔭 This is the NGC-5005 galaxy, located some 65 million light years away. The supermassive black hole located at its centre is estimated to be 30 to 85 times more massive than ours! HD: flic.kr/p/2rd9gfn

It's JWST's turn to observe M87, as it did a year ago today! Here's my processed version of that newly released data 🔭 Even in near-infrared that jet is wonderful 🥰 HD: flic.kr/p/2rdhh6w

While we are all waiting for Rubin's images, here's some new JWST! 🔭 This is the NGC-891 galaxy as seen by the JWST/NIRCam. The data was released earlier today, and I had some fun processing this edge-on galaxy observation! HD: flic.kr/p/2rcxXHR

Just amazing 😍🔭

Fuck.

The same, but not exactly?? 🔭 This is the NGC-4254 galaxy (M99) as seen by the JWST's MIRI (left) and NIRCam (right) instruments. This galaxy is located 45M light years away. Seeing in two infrared wavelengths offers two looks of the same object! MIRI: flic.kr/p/2rcdxQT NIRCam: flic.kr/p/2rcdxY8

@moudhy.bsky.social Hello Moudhy! I was wondering: do you know if there is any Babylonian/Assyrian tablet about cats? I was talking to friends about the tablets you share here, but I can't find one mentionning cats...

Behold the Evil Eye Galaxy! 🔭 👁️ This is the M64 galaxy as seen in 3 distinct wavelengths by Hubble and JWST (NIRCam and MIRI). The JWST data was released earlier today, it was really fun to process it right away! HD Hubble: flic.kr/p/2rbPfrM JWST: flic.kr/p/2rbPgBw MIRI: flic.kr/p/2rbP9Nh

An old classic, but it was observed by Hubble again back in December, so here's the processed image of that last observation! 🔭 This is the jet produced by the M87 supermassive black hole, located some 55 million light years away! HD: flic.kr/p/2rauPHp

I think we all need a pause right now while waiting for more Musk/Trump development, so I am offering you a JWST image! 🔭 This is the Rho Ophiuchi cloud, ~400 light years away from us, seen in infrared light. It seems as explosive as the feud today 🤫 HD: flic.kr/p/2r96wp9

As 'gotchas' go, "I willingly supported someone I knew was involved in major child trafficking crimes but actively kept it under wraps until now" is... an atypical approach, I'll say that much
