Thankful that ACLU is pushing on this. While I do think there's a place for AI in society moving foward -- dodges tomatoes -- I 100% think that this is not it. www.thebanner.com/community/cr...

Jay Bhattacharya pulls a study because he doesn’t like the conclusions. I cannot explain how bad this is and how it reeks of the stench of ideological zealotry and has no basis in science. www.nytimes.com/2026/04/22/u...

Hubble marks its 36th anniversary with a shimmering close-up of star-formation in the Trifid Nebula! Tiny, actively forming stars are eating and spewing material all around. (One at top left in brown, and two fiery red jets.) Explore it all: https://news.stsci.edu/4cvi5jL

House SS&T Dems just issued a report re NASA and the FY2026 budget: "Mission Aborted: How NASA Illegally Implemented the President's Budget Request Without Congressional Approval." Calls on Isaacman to "defend" NASA and not do the same w/FY2027 request. democrats-science.house.gov/imo/media/do...

So cool that Annual Reviews sent me a physical volume of ARA&A 63! A great memento from when I served as a guest reviewer.

I did not have "Allbirds pivots to AI" on my bingo board

Excited to deliver the University of Kentucky astro seminar! First time in Lexington too -- I did not realize how many horse farms there are here! www.as.uky.edu/physics-astr...

Just taught a bunch of 5-year-old kids about astronomy. They sure had a lot of questions!

The Center for Computational Astrophysics @flatironinstitute.org is hiring a new Research Software Engineer to work on @astropy.org and to support the software and computing efforts within the CCA. Apply by May 22! apply.interfolio.com/184639 🔭 🧪 ☄️

Absolutely worth a read!

We're so cooked

🔭 Paper day, and it’s a big one! We have found the most metal-poor object known in the universe. It’s a star, and it comes to us from our nearby friend the Large Magellanic Cloud. Out in Nature Astronomy today: rdcu.be/fbylI

Dr. John Wu, PhD, Associate Astronomer and the Applied AI Scientist at the Space Telescope Science Institute, presenting his talk "Short Stories of AI in, and for, Astronomy" at our hybrid seminar series! To sign up for future seminars, join our email list cosmicai.org/get-involved

"i have two Microsoft Outlooks, and neither one of those are working." The Astronauts truly representing us all up there.

New paper on the arXiv today!! We discover constellations in DESI’s galaxy map and explore their cosmological implications. Here’s a thread of the key results. 🧪🔭 Paper: arxiv.org/abs/2603.29912 Website where you can find your own galactic constellations: cmlamman.github.io/galactic-con...

The joy of being a STScI astronomer 🤩 Spotted at BWI airport

cosmicai.org/events/sprin... Come listen to some vignettes about AI in astronomy and AI for astronomers

@emily.space is doing amazing things for the astronomy community on atproto. Open, real-time data streaming for gravitational waves and other observational data, custom feeds, PDS hosting. #astrosky #atscience #atmosphereconf

Looking forward to giving the University of Texas Department of Astronomy Colloquium next week! This will be fully focused on astronomy. I'll also be giving the CosmicAI seminar, featuring vignettes of AI in, and for, astronomy. Stay tuned for more! astronomy.utexas.edu/events/astro...

Hey all, I think we need a little good news right now, so: Our new/upcoming "Radical Spirits in Reservoir Hill" walking tour is now open for booking! fullstorybaltimore.tours/our-tours/#r... This tour is currently scheduled for weekends in April; we'll decide later about future availability...

The difficulty in the classroom *is* where the learning happens in the classroom.

How can you not be romantic about baseball. Beautiful performance by Venezuela.

Four years in and academia is genuinely still fun. Why? I'm not trying to maximize my h-index. I don't care about group building or commanding grants. I'm just here to have fun. It's like founder control. Forget shareholder value or YoY growth. I'm optimizing for my own curiosity.

⚛️🧪🔭 if you have taught QFT and want to share tips/lecture notes, please weigh in! replies are open! I'm only doing QFT I, and my guess is that QFT II will not be offered.

There are few things more beautiful than an Ohtani homer

The best part about finding out my JWST proposal was ranked in the bottom quintile: it forces me to be humble and reminds me that I have lots to learn. Sure, it's frustrating and slightly demoralizing, but it's also relieving -- I haven't peaked yet (or so I tell myself).

Every lunch conversation at STScI today:

When I moved from assembly language to C, from C to C++, from C++ to Java, from Java to Kotlin, from Kotlin to Python, the earlier skills indeed rotted away. I didn't much care. I can get them back easily enough if I need to. 8/9

To what extent are star cluster ages encoded in their environments? Congrats to my coauthors Javier Viaña, Janice Lee, Andrew Vandenburg, and the PHANGS collaboration on this paper! (and be on the lookout for a part two 👀) arxiv.org/abs/2603.07289

This week I'll be delivering a talk and leading a tutorial for the Language AI in Space Sciences Workshop in Baltimore, hosted at STScI. So excited to see folks from all disciplines join the conversation -- including astronomers, engineers, computer scientists, librarians, and linguists.

I'm real bullish on AI capabilities. It's humans I'm skeptical of: I'm really worried about careless use of AI which is basically all I've seen so far

uh oh Donald Knuth is a Claude booster now

I kind of like Zitron because he had the intellectual humility to admit that he doesn't know a thing about software engineering, but he's also now staked his career on writing about how AI can't do anything (including software engineering).

Hey #Astro skeeters, check this out! arxiv.org/abs/2602.22035

A star has died! For the first time, astronomers have used #NASAWebb to identify which specific star exploded as a supernova. The star—located in galaxy NGC 1637—was a red supergiant surrounded by so much dust that it was invisible to Hubble: https://news.stsci.edu/4alt51V

So I finally finished this book and it's really really good! They say never meet your heroes but getting to know her through her autobiography, her scientific outlook and politics hold up extremely well! Some highlights for me: 🔭🧪🧵

I don't pay for Claude (web version), so I wonder what the free tier would say ... hang tight, I'll screen cap the first response
