Anyone else going to COLM? Give me a shout! Also, check out our poster on evaluating LLMs for astronomy research. This work came out of our 2024 JSALT research and was jointly led by undergrads Alina Hyk and Kiera McCormick!

Thanks Baltimore DOT for penalizing 40+ mph speeders more harshly, but by that point shouldn't you be revoking their driving license?

The jellyfish #galaxy MACSJ0451-JFG1 in a galaxy cluster with #JWST NIRCam. 🔭 The galaxy is experiencing ram-pressure stripping. It moves trough the intracluster medium and is stripped of gas, leaving tails that form stars. My image processing from today: commons.wikimedia.org/wiki/File:MA...

And I didn't even have to pay a billionaire! Wow!

Impressive sleuthing! Careful observations 🤝 careful statistical modeling

Hello everyone! My first Bluesky posts! I am very pleased to share that my 3rd first-author paper of my PhD is now available on arXiv! The paper has also been submitted to MNRAS following minor suggested revisions from the anonymous referee! arxiv.org/abs/2509.08045 Thread on the details 🧵

Thanks to UMaryland Astro for inviting me to give the Center for Theory and Computation Seminar!

I just watched the strangest #orioles walk off win

We're incredibly grateful for Emily having hosted the Astronomy feed herself for two years — a feed which we use every day! There is now an option to support the hosting of the feed so that we can all continue to share astronomy on Bluesky. 🔭☄️

Ma'am this is a ML x Astro/Cosmology email d-list

For the last two years, I've been paying for the Astronomy feeds hosting myself. It has been a privilege to grow our community here, but I also shouldn't keep doing it for free 😅 That's why I'm delighted to announce that we now have a donations page on Open Collective! 🔭☄️ #astrophotography

This, except in Jan 2020

DERRICK HENRY COME GET YOUR CROWN

I don't think I've ever seen a no hitter bid, with just 1 out to go, somehow turn into a loss. Certainly not with a 3 run differential. #orioles

Truly a wild game. 8 and 2/3 innings of no hitter from incredible performance by Yamamoto. And then a home run to break it up. Double, HBP, BB x2, to make it 2-3 with bases loaded... and then the walk off single that scored 2 more. Insane

First half of the 1st quarter and it looks like the #Longhorns forgot how to play football. I go and put my daughter down for her nap and they've scored 21 points?!

Another fantastic paper that arose from our @kitp-ucsb.bsky.social GalEvo23 program. This one is from the inimitable Kartheik Iyer, who also shared a fantastic takeaway figure on how simulated feedback affects galaxy star formation histories. #AstroSci #extragalactic

Would sure be nice if we could go a single week without one of my kids getting sick. Like come on, it's still summer. Am I asking too much?!

Does this very good boy know that he could be making $30/hr doing just that?

Kinda bonkers to see Kpop Demon Hunters blowing up. It feels like I grew up in a different world... Growing up I remember multiple friends mentioning that I was the first (or only) Asian person they had met. (In Sulfur, Louisiana -- okay no surprise rhere -- but also I heard this in rural NJ)

Wow very interesting idea. Definitely want to read the paper now. Nice job astrobites writers!

I've received lots of crackpot physics emails, and this 200 page manifesto looks like every other 200 page "retired engineer" crank manifesto... But this is the first one I've seen which claims an endorsement from Marx.

Don't look now but the #Orioles worst rotation pitcher has now thrown 7 perfect innings against the Astros...

Happy nine years of marriage to us!

Amazing stuff for #astrosci!

Awesome work by our multidisciplinary team spanning HCI/psych/CS/astronomy and co-led by fantastic undergrads! Learned a lot about how to better evaluate AI for science, both quantitatively and qualitatively... also how astronomers learn to (dis)trust LLMs for use in research! #AstroSci

Check out my new blog post discussing graph neural networks for astrophysics—specifically, how galaxies relate to their dark matter subhalos in the context of their cosmic environments. jwuphysics.github.io/blog/2025/07... #astrosci

I've had a few other former astronomers reach out to me lately about transitioning into data science/ML, and I decided to write about it. This is my personal journey from astro to ocean, and the most useful steps I took along the way.

STScI's Jason Tumlinson spoke this morning about seeking our origins in the universe with the Habitable Worlds Observatory. Scientists from around the world gathered in Washington, D.C., to discuss the search for signs of life on planets orbiting other stars. #HWO2025 🔭 🧪 ☄️

Even though I'm already past my self-imposed yearly quota for reviewing papers, I can't help but accept this latest one since it's *not* about machine learning in astronomy...

The Senate just posted the report language of its FY26 science appropriations bill. This text lays out what they want done and carries the force of law if it is included in the final spending bill. It's a line-by-line refutation of Trump's proposed budget for NASA and NOAA.
