arxiv.org/abs/2509.14423 ⭐️paper day!⭐️ hey now, we found thousands of stellar variability periods, including ~26k very high likelihood new ASAS-SN rotation periods from cool dwarfs! (also I have missed abt 5 typos in this version already, but it’s only been submitted to ApJS so it’ll get fixed!)..

Join us on tonight from 8:30-10:30pm for public night at the MSU Observatory! Visit our website for FAQs: web.pa.msu.edu/astro/observ... Address: MSU Observatory, 4299 Pavilion Dr, Lansing, MI 48910

This is the letter sent by NASA GSFC Associate Center Director to the local Union President regarding cessation of union activities at GSFC. NASA Wallops employees got an identical letter. The wording matches a letter that was sent by the JSC Center Director. More: nasawatch.com/personnel-ne...

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

From Chloe Klare: Interested in the definitive, absolutely objective ranking of the best differential equations in astronomy and astrophysics?? Read on!! 🔭✨☄️ astrobites.org/2025/08/18/t...

👀👀👀 #SN1987A pre-print 🔭 New #JWST results (epoch 13500 days post-explosion). The spectra are *unreal*. A new iron signature could be interesting. Q: So, is there (finally) a pulsar? A: Astronomers are still looking, but there is some indirect evidence for it so far! arxiv.org/abs/2508.03395

so excited to be presenting at @astronomyontap.bsky.social - Lansing on 8/13 with Laura Chomiuk !!!! hope to see you there : )

Someone made this list of the reps that are publicly on the fence. Call these ones, even if they are not in your district!

It's not just #NIH. It's not just #NSF. It's not just #NASA. The whole scientific community has to make clear that all science across fed agencies is being destroyed in the US. We can't just ask for our particular piece of the pie. The whole pie is being thrown out - saving your bit won't work.

wait as a frequent SOAR observer how did i not know this 😭🩵

Today for @blackinastro.bsky.social's theme of #ShareTheUniverse for 🪐 Black in Space Week 🔭, we have two very special interview articles with black astronomers Logan White and Phoenix-Avery Sarian! Summaries for each article and links in the thread below ⬇️!

This month we highlight a score of Black astronomers trying to pursue their ambitions without fear, and Black In Astro, an organization supporting predominantly early-career Black people working in the space sciences. Editorial: www.nature.com/articles/s41... #BlackSpaceWeek #EquityInSTEM 🔭

The @esa.int Gaia satellite takes its final ever observations today 😭🔭 During its final few months of life, some technical tests will be performed, during which it will be much easier to see from Earth than usual. ESA published a guide on how to try and take photographs of the satellite:

hi friends -- I'm a 3rd year phd candidate in astro studying binary millisecond pulsars, mainly at optical and X-ray wavelengths. aside from research, I'm passionate about community building, inclusion in astro/physics, and queer visibility. happy to link up if any of that speaks to you!
