There are a weirdly large number of hallmark Christmas movies where an astronomer is one of the pair. 🧵

I’m watching A Christmas Star with my mom and kid. I believe this is the movie that @astronomisty.bsky.social live tweeted several years ago. It is awkward in Hallmark movie form.

Talk to your institution's librarians. They really know what they're doing for this kind of thing.

This was a very enjoyable collaboration with @3blue1brown.bsky.social . Tanya Klowden and I are continuing to work on developing this material into a popular science book; we will share our progress on our Instagram at www.instagram.com/cosmic_dista...

I’m at #AAS245 until about midday Tuesday. I’ll mostly be hanging around outside the conference hall proper to avoid paying registration.

I’m also a crusty old scientist, but I don’t share your pessimism. I see it as another potential tool to get me where I want to go. It’s not without its problems, but the same could be said for most tools that have improved scientific endeavors.
