Twee clusters van sterrenstelsels staan op het punt opnieuw te botsen

De ongewone astronomische botsing biedt nieuwe inzichten in de dynamiek van dergelijke botsingen.

Deze afbeelding toont de botsende clusters van sterrenstelsels die het systeem PSZ2 G181 vormen in het blauw, geflankeerd door een paar radi

I just love this institute so much...

No just because of the best memes, but well... The memes are the best!

Bon anniversaire !
25 années déjà depuis son lancement, et toujours en train d'observer activement le ciel en rayons X ! @europeanspaceagency

Real happy birthday to our dear XMM-Newton, who turns 25 today! I did my first paper using XMM data, and I'm glad to see that many years later folks are still getting the chance to get started with ESA's exceptional space telescope.

[Joyeux anniversaire, #XMMNewton ! 🥂 🎉 ] 25 ans. Cela fait 25 ans que l' #Observatoire XMM-Newton de l' European Space Agency - ESA lancé par une fusée #Ariane5 scrute notre #Univers dans le domaine des rayons X.

Récemment, les données acquises par cet observatoire ont permis de comprendre l'origine des #aurores X aux pôles magnétiques de #Jupiter, de contraindre les #théories sur l'intérieur des étoiles à #neutrons, de révéler de gigantesques #éruptions en périphérie d'un #TrouNoir supermassif, etc : esa.int/Science_Exploration/Sp

Depuis quelques années, l'avenir se dessine, avec la mission #Athena, et le #spectromètre de nouvelle génération #XIFU ...

Happy birthday -Newton!

I just love the breadth of science that an observatory can achieve: from understanding Jupiter's aurora to what happens very close to black holes or inside neutron stars.

And I also love than when building a space mission with a nominal lifetime of 4 years & then successfully operate it for 25+, with it still delivering cutting edge science as if it weren't a grandparent of a mission!

Infographic titled "XMM-Newton celebrates 25 years in space" showing the spacecraft on a background of a space image + the number 25. Around it several numbers for the mission are listed: 1 million detection o X-ray sources, 1.5 billion kilometers travelled, 8000+ papers, 15000 scientists, 530 PhD theses, 16800 observations in public archives, etc.

[Education à la #Science] La 3ème édition des « Master Classes Internationales en #Astrophysique » s'est tenue ce jeudi 5 décembre. Elle a rassemblé des chercheurs de l'IRAP, de l'Instituto de Física de Cantabria (IFCA, CSIC-UC), de l'Institute for Astronomy, Astrophysics, Space Applications, and Remote Sensing (IAASARS) du National Observatory of Athens, et des lycéens des trois pays, autour d'une thématique : l'astrophysique des #rayonsX.

Au programme : initiation à l' #astronomie des rayons X, contribution à la constitution d'un #catalogue de sources observées par le satellite #XMMNewton de l'European Space Agency - ESA, présentation du projet #XMM2Athena, etc. Objectif : susciter des vocations scientifiques ! 👍

Gotta love the power of multiwavelength astronomy! Remember the new early release observation images from two months ago? ▶️ esa.int/ESA_Multimedia/Images/

Folks have combined it with (archival - since galaxy clusters are so big that they don't change on human timescales, we don't need simultaneous data!) X-ray images. So you can now see both, where the galaxies in the cluster are - and where all the hot gas is. Slider image here:

XMM-Newton detecteert ultrasnelle zwartegatwind in Markarian 817

Markarian 817 is een Seyfert 1-sterrenstelsel dat ongeveer 430 miljoen lichtjaar van ons is verwijderd in de richting van het sterrenbeeld Draco – Draak. Het bevat een supermassief zwart gat met een massa van 81 miljoen zonsmassa.

Paper day for everybody involved and excited about #eRosita ! Here is the paper by my Kostas Migkas and his colleagues who, for the first time, performed a robust cross-calibration of eROSITA vs Chandra and XMM using a large galaxy cluster sample. The findings are crucial for a wide range of future X-ray cluster studies, and future eROSITA data will further improve these constraints!

Why space-based telescopes like or ? Because our atmosphere is incredibly good at filtering out radiation that is not in the visible or radio range.

That's obviously pretty good for humanity overall, but kinda inconvenient if we want to observe highly energetic X-ray photons from close to black holes or peer deep into stellar nurseries using infra-red light.

The image shows how deep into the atmosphere different kind of radiation penetrate. Only visible light and radio reach the ground; some of the IR radiation reaches down to about ~10km, and is reachable by jets. Gamma-rays, X-rays, UV, a lot of the IR, and microwave radiation have to be observed from space.
