So... is this giving "microscope" to you or....?

Started scripting this week's video.
It's going to be about a company out in Russia that wants to beam adds into the night sky via space satellites.
Sounds like maybe one of the worst ideas ever, but thankfully, astronomers are standing up for us.

Hmm, new (?) #IAU website tries to load stuff from Google and Azure, and
$ host iau.org
iau.org has address 104.16.130.63
iau.org mail is handled by 10 smtp.google.com.apparently the mails go to Google, too.🤔

CW: To IAU members (International Astronomical Union)
#Fediverse call to action: Let's advocate for IAU to join Mastodon instead of Bluesky!
Are you an IAU member and have received the May 2026 IAU Orbit Monthly Circular? It contains a poll asking you if the IAU should start being active on Bluesky. I sent back an e-mail back suggesting they try Mastodon instead (which I addressed to Anne Thieme, see https://www.iau.org/IAU/IAU/News/Ann2025/IAU-Membership-Coordinator.aspx). Maybe you would like to second that suggestion by also contacting them. Let me know if you did?

"@nasaadmin's initiative could catalyze fresh research and discussion within the astronomical community, potentially leading to proposals that challenge or refine the @iau_org criteria. At the same time, it risks being seen as a distraction during a period when many fear for the future of space science funding."

Happy to see the statement on #universityrankings by the International Association of Universities #IAU, the largest and most international university network: https://iau.global/news/iau-note-on-rankings-released. Sort of proud to have played a role in that. Moving away from rankings, step by step. I look forward to seeing similar statements from #LERU, #TheGuild, #AURORA, #YERUN and others. Solidarity among institutions is crucial amidst authoritarianism and commercial capture.

"The mean apparent magnitude of Amazon Leo #satellites is 6.28 based on 1,938 observations. For spacecraft in their operational mode, 92% exceeded the brightness limit recommended by the #IAU for interference with research, while 25% distract from aesthetic appreciation of the night sky. The reflective characteristics are similar to Version 1 #Starlink spacecraft."

The reason I am in Argentina
More info here: https://congresos.unlp.edu.ar/astralx/
I'm really excited to teach here - I wanted to do one of the capacity building workshops for a while.

A message from Lidia Oskinova, President of the IAU commission G2 Massive Stars:
"Everybody is welcome to join an on-line seminar on December 1st (Monday!) at 16:00 CET
Title: What Stars Are Made Of: Celebrating One Hundred Years of Cecilia Payne-Gaposchkin's Revolutionary PhD Thesis
Speaker: Floor Broekgaarden (University of California San Diego)
https://rediris.zoom.us/j/6313376939?pwd=akRrd2dmb3dnbDN0MmRCallTTHlLQT09&omn=95383862762
A century ago, Cecilia Payne-Gaposchkin's PhD thesis, Stellar Atmospheres, transformed our understanding of the Universe. Famously described by Otto Struve as "the most brilliant PhD thesis ever written in astronomy", Payne-Gaposchkin's work revealed that stars are composed primarily of hydrogen and helium - an insight that overturned the prevailing belief that stars shared Earth's composition.
We invite you to celebrate the centennial of this landmark achievement and to reflect on the courage, creativity, and intellectual clarity that defined Cecilia's science. [...]"
