Enjoyed a fall nature walk yesterday followed by some live music in a churchyard with a big group of picnicers. (I skipped the bike ride, but maybe next year.)

It might not be all in one project, but I'm going to try to hit 50k again this year. It's been a long time since I wasn't working on the same story every November and I'm looking forward to the uncertainty.

I love watching @thatbronzegirl.bsky.social DM because she makes me feel so much better about my lack of a poker face while DMing. Laughing with your players is the best. #criticalrole

I know I'm a night owl, but sometimes even I surprise myself with how much energy I have at 3am just because I was invested in a good story.

Maybe it's the introvert in me, but if I was still waiting in line for a bar at midnight, I would simply go home.

Today I salute Elizabeth Brown (1830-1899) who "with the gentle persistency which characterised her...would not take 'No' for an answer", was a key architect in the founding of the British Astronomical Association at a time when the Royal Astronomical Society was not admitting women! Pure legend 🤩👩🔬🔭

Cecilia Payne-Gaposchkin ✨ figured out what stars are made of ✨ when she was just 25. 🔭🧪
Her PhD thesis basically established the Harvard astro department — at a time when Harvard didn't officially allow woman students.
I wrote this little profile to mark the 100th anniversary of her thesis:

New Arabic records from Cairo on supernovae 1181 and 1006
The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000-5000 yr), the unusual star IRAS 00500+6713 with a surroundin...
