Galileo Galilei Discover what Galileo himself didn't, find new planets and star systems!

Have you tried Galileo Galilei? It’s by the same designer as SETI and I think it’s an even better game

SETI: Search for Extraterrestrial Intelligence Search for signs of alien life by launching probes and analyzing distant signals.

This board game is amazing!

It's super complicated and VERY true to the science. Every astrobiologist board game geek should get a copy! I'm SO impressed at the research behind this game.

I would LOVE to review this game! Anyone know how/where I could do that?

This sounds very doom-ish but SciX works great for astro, I have made the switch entirely from ADS and haven't lost any function or speed. 🔭 (would be interested in hearing about usage in other fields)

Virtual Astronomy Software Talks comes early this month!
Come (virtually) hear about Julia in Astro tomorrow, with 2 talks focusing on Julia:

Paul Barrett: JuliaAstro
Paul Tieda: Comrade.jl

I'm happy to report that "Scenario 2" won't be necessary, as NASA has just communicated to us that SciX funding will continue in 2026 (albeit at a reduced level). Therefore, we will not be forcing astronomers to leave ADS, but rather develop a plan that allows a longer transition.

Is it an early Thanksgiving miracle?! Kind of feels like one!
