"@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."

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. [...]"

Message from the International Astronomical Union #IAU:
IAU Hands-On Workshops - Call for Proposals for Workshops in 2026
The IAU calls for applications to organize workshops under the IAU Hands-On Workshops (I-HOW) initiative. These workshops aim at training early-career scientists from developing countries in accessing, reducing, and analysing the vast amount of data available in astronomical archives across the world, and using them for their research projects. Proposals to organise one of these workshops shall be submitted using the application form provided on the website by email to one of the members of the I-HOW Steering Committee.
The deadline for applications is December 31, 2025.
More information on the characteristics of the initiative, the procedure and selection criteria for workshops, and a link to the application form are available at: https://www.iau.org/Iau/Iau/Science/Trainings---Workshops/I-HOW-Hands-On-Workshops.aspx
