Follow-up comment on how bad it is on the ground at NASA Goddard Space Flight Center. 🔭
To complement your suggestions, I want to declare that astronomical sources have an E^0 spectra so that we can have more photons in X-rays ! 😉
It moves! We can watch as the Kepler supernova remnant changes over a quarter of century in X-rays from Chandra. #aas247

XRISM has made the first ever X-ray detections of chlorine and potassium in the remains of a supernova, showing that these elements critical for the formation of life are indeed spread throughout the cosmos by exploding stars

Retro-active measure !

One of the awesome bits of supernova science I always love is when someone finds a new ancient record of a supernovae! In this case new Arabic records for SN1181 and SN1006 from poems!

Stop Loi Duplomb !
Loi Duplomb : Montrons que la société refuse ce retour en arrière.
Une pétition citoyenne a été lancée pour exiger la sortie progressive des pesticides de synthèse.
🎯 Objectif : 500 000 signatures pour imposer un débat à l’Assemblée nationale.
📢 Signez et partagez !
Pensez a signer cette pétition !
Beaucoup d'entre nous ont un souvenir lié au Palais de la découverte.
J'y ai pour ma part travaillé pendant ma thèse et il faut que ça puisse continuer pour les nouvelles générations !
I am furiously, flamingly, incandescently, *supernova-levels* of angry right now.
Trump is trying to kill NASA science. And hoo boy, do I have something to say about it.

Following the inspiration of @ohdearz.bsky.social @theplanetaryguy.bsky.social @jtuttlekeane.bsky.social here’s the NASA fleet with the proposed budget cuts. Red X’s will be fully defunded, green X’s will lose all NASA funding but have other funding sources, and exclamation point means >50% cuts
Don't you dare touching my Fermi gamma ray space telescope!!
No other replacement are planned for decades
Oh no 😱
Is there hope that Sente reduces this nightmare ?
Il ne manque que 50000 signatures pour s'opposer à cette saloperie des âges obscurs que sont les "thérapies de conversion" dans toute l'UE.

188 millions en moins sur le spatial… après les nouvelles affligeantes côté NASA, on va pas faire beaucoup mieux en France…
In 100 days in office, US President Donald Trump has destabilized eight decades of government support for science.
This has included terminating more than 1,000 grants in areas such as climate change, cancer, and HIV prevention.
Will US science survive Trump 2.0?

![Dear Members of the Harvard Community,
For three-quarters of a century, the federal government has awarded grants and contracts to Harvard and other universities to help pay for work that, along with investments by the universities themselves, has led to groundbreaking innovations across a wide range of medical, engineering, and scientific fields. These innovations have made countless people in our country and throughout the world healthier and safer. In recent weeks, the federal government has threatened its partnerships with several universities, including Harvard, over accusations of antisemitism on our campuses. These partnerships are among the most productive and beneficial in American history. New frontiers beckon us with the prospect of life-changing advances—from treatments for diseases such as Alzheimer’s, Parkinson’s, and diabetes, to breakthroughs in artificial intelligence, quantum science and engineering, and numerous other areas of possibility. For the government to retreat from these partnerships now risks not only the health and well-being of millions of individuals but also the economic security and vitality of our nation.
Late Friday night, the administration issued an updated and expanded list of demands, warning that Harvard must comply if we intend to “maintain [our] financial relationship with the federal government.” It makes clear that the intention is not to work with us to address antisemitism in a cooperative and constructive manner. Although some of the demands outlined by the government are aimed at combating antisemitism, the majority represent direct governmental regulation of the “intellectual conditions” at Harvard.
I encourage you to read the letter to gain a fuller understanding of the unprecedented demands being made by the federal government to control the Harvard community. They include requirements to “audit” the viewpoints of our student body, faculty, staff, and to “reduc[e] the power” of certain students, faculty, and …](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:2r7ljryv4mdb7e4svonbhugk/bafkreic7mubtl3qojedpbpjusckhkpnj5tp3xltvl65ccqmpjy2rgh2jmi)

Congrats 🎉
Welcome little one!
I think this indeed goes beyond the worst case scenario that people could have imagined.
The word extinction level is appropriate here.
And would cascade into EU science at many levels 😱
Among other disasters, the proposed budget would force closure of the NASA Goddard center !! 😱
10'000 employees and the major facilities that made JWST integration possible.
Would also kill many other telescopes.
Hope Congress will pick a fight on this.
Wow le site CTAO sud est vraiment le plus collé à cette usine 😱
Scientists have just cured pancreatic cancer in some patients with personalized mRNA vaccines. Pancreatic cancer. And this Trump administration wants to throw it all away.
They’re throwing away a cure for cancer.
