I've been thinking for a long time whether I should publish this for you. Now it is hard for me to describe this post in words. I will just leave it here to share with you the pain of my country. The war that Russia started.

Absetzung der Astrologie-Show nun bestätigt, berichtet der Standard. Sehr erfreulich, dass im ORF diesbezüglich ein Umdenken stattgefunden hat 👏 derstandard.at/story/3000000… @univienna
Bestätigt: ORF versenkt die umstrittene "Astro Show" endgültig

Das Format ging nach herber Kritik nur einmal auf Sendung. Moderatorin Sasa Schwarzjirg tauscht die Sterne gegen Promigespräche im privaten Umfeld, berichtet die "Krone"

Over the past years, a team of ~100 astronomers from around the world worked to hone the science cases for #AtLAST.  The result is a compendium of eight white papers and an overview report. Read more about them and find all the relevant links here: atlast.uio.no/news-and-event…
Diagram displaying the three science questions driving the AtLAST design: Where are all the baryons? How do structures interact with their environments? What does the time-varying (sub-)mm sky look like?

This has been waiting for a long time, but is finally out. This is actually a “just” a pre image to find spectroscopic targets to measure the ice content of the cloud, but I knew it would be visually spectacular. The aligned protostars were a total surprise! #jwst @NASAJPL

The stars, they aligned 🎶 See how those bright red, clumpy streaks are all slanted in the same direction to the same degree? They show aligned protostellar outflows, or jets of gas from newborn stars. Webb captures this phenomenon for the first time: go.nasa.gov/4b9t6o9
A portion of the young star-forming region Serpens Nebula. It’s filled with wispy orange and red layers of gas and dust, and within that orange dust, there are several small red plumes of gas that extend from the top left to the bottom right, at the same angle. There are wispy blue filaments of glass in the bottom right corner of the image. Small points of light are sprinkled across the field, brightest sources in the field have extensive eight-pointed diffraction spikes that are characteristic of the Webb Telescope.

Every #DDay I come back to Harry Billinge ❤️ If you’re tempted to moan about something meaningless or complain today… watch Harry and think about what he, and many others, went through for the freedoms we all too often take for granted. There aren’t many of those heroes left but they have so much to teach us. We’ll be playing music to commemorate the anniversary throughout the day on @ClassicFM #DDay80 #LestWeForget

¡Feliz San Isidro! Quejarse de Madrid y de los madrileños se ha vuelto un meme en redes sociales. Y muchas veces con razón. Hoy quería compensar hablando por un día de lo que me gusta (hace falta más positividad aquí). Un hilo personal de cariño a Madrid 👇

Did you know there is a publicly available #AtLAST sensitivity calculator? It's very easy to use especially in its online version. More info here: atlast.uio.no/news-and-event…

🔭 Astrophysicists from #univie found that measuring star ages through different methods uncovers a 5.5 million-year gap: it's like measuring when they're born vs. when they leave their 'stellar nest'. 👶✨ Read about this discovery in the Thread by @stem_univie: ⤵
