"@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."

"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."

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)

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. [...]"
