The President's Budget Request proposes a 47% cut to NASA Science, a 55% cut to NSF, and a 13% cut to the DOE Office of Science. AAS President Dr. Dara Norman sent a call to action to AAS members via email today. Urge your members of Congress to reject these cuts now! aas.org/reject-2027-...

More context on this #Artemis II image: * This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right * The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon: ☀️🌍🚀🌕

If all goes according to plan, in a few hours, a crew of astronauts will begin a journey that will take them on a loop around the moon. Here's a video that NASA put together to help people visualize the journey through space, first orbiting the earth before looping around the moon and flying home 🔭

Among the firsts of Artemis II, it will be the first time a person of color and Black astronaut (Victor Glover), first woman astronaut (Christina Koch), and first Canadian and non-US citizen astronaut (Jeremy Hansen) travel beyond low Earth orbit and to the Moon. 🚀

👇🏽 great example of how the NYT continues to — has never stopped — engaging in platforming anti-Black, genocidal rhetoric and how it is so normalized that it is not discussed in those terms (not a criticism of Victor, just noting the way our cultural vocabulary shifts for discussions anti-Blackness)

OSU astro coffee was so fun today! We talked about @clairelamman.bsky.social's Hawking radiation comic, OSU undergrad Mya Smedley presented on how lessons from SpongeBob (kindness, empathy, and passion) can be applied to astronomy, & we saw new XRISM results on M82! arxiv.org/pdf/2603.24674 🔭

very grateful to have finally made it in person to visit OSU since my virtual Price Prize talk in 2020. thanks to everyone for the invitation and especially @ohdearz.bsky.social for hosting! also love to brag about my awesome grad students!

Honored to have @carlnotsagan.github.io visit OSU today and give an outstanding colloquium on next generation simulations of massive star death & predictions for multi-messenger signals! 🔭🧪⚛️

#AAS248 The Society's FAMOUS Travel Grants program helps members from historically underrepresented groups attend AAS meetings. Grant requests for the summer meeting (14-18 June 2026) are due by 16 April. aas.org/grants-and-p... 🔭

Looking at the AAS jobregister lately, it seemed to me that there are less positions available in all categories than in previous years. Wanting to quantify, I used the wayback machine to check on the number of postings in the January-March window and it is quite depressing.

RCSA, @heisingsimonsfdn.bsky.social, the Leinweber Foundation, and Kevin Wells are funding the research of 7 collaborative teams in the 2nd year of #Scialog: Early Science with the #LSST, a 3-year initiative to ignite discovery with the @vrubinobs.bsky.social's Legacy Survey of Space and Time.

Do you ever just stop and think about how great Charles Yu's writing is? Anyway the first chapter of THE EDGE OF SPACE-TIME is called "How to Live Safely in a Science Factual Universe" -- iykyk Preorder here: www.penguinrandomhouse.com/books/746817...

final grades: posted! it’s been so inspiring working with our AMAZING senior undergraduate students this semester in my theoretical astro (stars) class @stewardobservatory.bsky.social. looking forward to hear about all the great things they go on to accomplish — admit them to your grad programs! 💥

some excellent talks to finish off day 2 of the ASTRO sessions here at the NSBP/NSHP 2025 Joint Conference! #nsbp #nshp

i’m excited to announce that i am hiring (again)! i am looking for a postdoc in computational astrophysics that’s excited about models of stellar transients and multi-messenger astronomy to join my group (star stuff @ steward) at @uarizona.bsky.social! apply here ✨💥: aas.org/jobregister/...

Happy to share that our book on computing in physics education has just dropped, @ioppublishing.bsky.social You can get all the chapters written by some of incredible colleagues who are improving physics education through computing right now. iopscience.iop.org/book/edit/97... #iteachphysics

Come join us at a fantastic physics department in the great PNW! The Oregon State University Department of Physics is looking to hire a tenure-track faculty in theoretical/computational condensed matter physics. Full consideration deadline: November 5th, 2025. jobs.oregonstate.edu/postings/173...

Enrico Fermi, one of the foremost physicists of the 20th century, was born #OTD in 1901. While most physicists focus on either experiment or theory, Fermi excelled at both. Now, estimate how many new physicists will be born today. 🧪 ⚛️ 🎢 (1/n) Image: New York Public Library

Astronomy 🔭 and physics ⚛️ GRFP applications are due Nov 14! Only seniors and 1st-year grad students can apply now (no second years).

Neutron stars are born running, and recent research explores just how fast they start off. aasnova.org/2025/09/24/k... 🔭🧪

Got my physical copy!

you already know all my tricks from my online notes, but I do have some stuff buried in homeworks, like this exercise of fitting to Cephids: zingale.github.io/computationa...

first day of year 2 as an assistant prof done ✅. very excited to be teaching 29 very bright undergraduate students in our upper level stars course this semester! ps. looking for engaging in class exercises for the 3rd/4th year level, so please share what has worked for you in the past! 🙏🏽

Results from the first part of our fourth LIGO @egovirgo.bsky.social KAGRA observing run are out today! We're pleased to share the largest catalog of gravitational-wave observations with more discoveries of black holes and neutron stars 📰 arxiv.org/abs/2508.18082 🔭🧪⚛️☄️ #GWTC4

once again reminded how much the grad school experience is shaped by your phd supervisor, and thanking the universe for my mentors. If I can do for my students what my advisor did for me, I’ll call myself a success 🙏🏽

Sometimes I lose faith in the book but then I go in to do a little edit and I’m like wow, I love this book I hope you will too 🤓 www.penguinrandomhouse.com/books/746817...

what are some of your go to self care practices for managing the stress with the start of the academic year?

To kick off here on bluesky I wanted to share some recent work from the group. First off arxiv.org/abs/2504.11537, the first science paper produced with our new GPU-accelerated GRMHD code GRaM-X.

Mary K Gaillard, a theorist who had a knack for telling experimental physicists where to look, died in her home on May 23 at 86. Dr. Gaillard was an unpaid scientist at CERN for more than a decade, & the first woman physicist hired & tenured at Berkeley: www.nytimes.com/2025/07/31/s...

i have been reflecting a bit over the past 24 hours since learning of the passing of bill paxton (creator of the MESA stellar evolution code) and the impact the code, the community, and specifically bill has had on mine and so many other junior scientist.

THIS EVENING, I'm talking about those mysterious "Little Red Dot" galaxies seen with JWST in a public "Deep Space Dialogue" facilitated by the Space Telescope Science Institute. Little Red Dots are super weird! 4:00 PM Pacific / 7:00 PM Eastern, live on Youtube! www.stsci.edu/contents/eve...

my materials for my grad stars + planets class is online here: carlnotsagan.github.io/ast545sp25/. there will be typos and some straight up errors. but most the material worked well for a 50m 3 times a week class. a lot new examples and reused from other folks materials.

I successfully defended my thesis and am now Dr. Caprice Phillips (its got a nice ring to it!). So thankful for my advisors and mentors including Jackie Faherty and @ohdearz.bsky.social and friends who were here to support me. Im the 2nd Black women to get a PhD from my department. Full of joy.

Hey #Lansing area folks, I'm giving a public talk on the recent impacts on science education and ways we can advance science as part of @astronomyontap.bsky.social on Wednesday. Please consider joining. #SaveNSF

I see a lot of people talking about how "we just need to explain science more to the public". The state Space Grant programs (one issued in each state) does incredible deep and wide outreach work - supporting education at every age and stage, nurturing science interest.
