Let me recommend grabbing a cup of tea & reading this really thoughtful piece from the inimitable @hogg.bsky.social on moderating AI/LLM use in astrophysics. 🔭
"the real question we face is not ... how we do astrophysics. It is the question of why we do astrophysics."

Our NASA’s Pandora space telescope is on orbit!! Congrats to the team and NASA, LSP, SpaceX, and everyone who helped to get to this exciting point! What will Pandora do and why is it important for exoplanet science? Read my short article on this: theconversation.com/nasas-pandor...
NASA’s Pandora telescope will study stars in detail to learn about the exoplanets orbiting them
The findings from Pandora will complement data from the James Webb Space Telescope to give astronomers more insight into stars and planets outside our solar system.
