Welcome new followers! I’m interested in astronomy education and outreach, and count myself lucky to have a job managing @hausderastronomie.bsky.social and @astro4edu.bsky.social that allows me to follow that passion! I also post about politics, mostly related to climate change. 1/

CO₂-Gehalt der Atmosphäre auf Rekordniveau und der Anstieg von 2023 zu 2024 so hoch wie noch nie.
Warum? Natürliche Senken werden zu Quellen: Ozeane speichern weniger, Wälder unter Stress stoßen CO₂. Waldbrände zerstören Biomasse und damit CO₂-Speicher.
Meine Einordnung in den Tagesthemen.

Oh ja! Das hatte ich neulich bei der Rückfahrt von Dresden. Erst Panik weil in Dresden "Ihre Verbindung ist nicht mehr fahrbar" angezeigt wurde und dann ging es nur um das letzte Mini-Stück von Mannheim bis HD, das ich ändern musste.

Wobei ich zu erinnern glaube, dass „Verbindung nicht mehr fahrbar“ mich auch schon mal mit Ersatzzug-mit-anderer-Nummer-aber-gleicher-Strecke-und-Zeiten gelinkt hat.

Ein Gutteil davon geht auf brennende Wälder zurück, die gleichzeitig als potenzielle Senken ausfallen. Dabei hatte die Welt doch versprochen, die Abholzung der Wälder zu bremsen/zu stoppen...

Dass gerade jetzt, in einer Zeit, in der überall die Moral flöten geht, in der Tabubrüche begangen wären, in der die Grenzen des Sagbaren täglich überschritten werden, tatsächlich Leute eine "Übermoralisierung", eine moralische "Überempfindlichkeit" diagnostizieren, ist erschreckend und gefährlich.

Wie BMI und @diplo.de mit diesen Menschen umgehen, die sich auf uns verlassen haben, der Aufwand, den sie dafür betreiben, 2.000 Menschen von unseren Grenzen fernzuhalten, die unwürdigen rechtlichen „Tricks“, die sie sich dafür ausdenken — ekelhaft.

I’ve heard something similar about international collaborations with NASA. By now, NASA has reputation of being somewhat unreliable, having backed out of a number of agreements in the past. Still an attractive cooperation partner of course (at least so far), but known to be a risk.

Yeah, my initial reply was not 100% clear on that. Sorry! I meant how the star distribution in the Star Wars galaxy itself would create a hazy band in the sky (and hence in many shots of star fields), analogous to our home galaxy, the Milky Way, appearing as such a band in our own night sky.

dim smudge that the Andromeda galaxy looks like from Earth). But just to make sure there is no misunderstanding: I was talking about the Star Wars galaxy itself, and how one would see *that* as a hazy structure in certain Star Wars star fields, if the modeling were realistic in that respect. 2/2

I use that particular screenshot in one of my galaxy lectures, since it can be used to understand surface brightness, and to introduce the distance-independence if surface brightness (which is the reason while even from that outside perspective, a galaxy would in reality only look like the same 1/

A lot of comments on Mars rovers or Moon landings, but it's important to remember that the planet NASA studies most is Earth. This is less about cutting flashy things like moonwalks and more about keeping communities in the dark on climate, weather, agriculture, pollution, natural hazards, and more.

One surprisingly heartbreaking thing about living in these times is seeing young people who finally made it to college/graduated/got a job/achieved the thing they’ve worked so hard for… just watch their opportunities disappear. And it’s even worse because absolutely none of this had to be happening.

Cool! Question for @tvaziri.com - does the new star field tool model something like the Milky Way's on-sky appearance as well? May be I'm misremembering, but I don't recall that for any of the movies. Bit of a contradiction if all of that is supposed to happen "in a galaxy" (even if far, far away).

How W. E. B. Du Bois responded to government policing of "anti-American" sentiment during the 1910s:

"I took great satisfaction in being able to sit back in my chair and answer blandly, 'We are seeking to have the Constitution of the United States thoroughly and completely enforced.' ”

Federal agents invaded even the offices of The Crisis and the National Association for the advancement of colored people and asked searching questions: " just what, after all, were our objects and activities?” I took great satisfaction in being able to sit back in my chair and answer blandly, “We are seeking to have the constitution of the United states thoroughly and completely enforced.” It took some ingenuity, even for Southerners, to make treason out of that.
