It's Friday, and apparently bluesky is ready for this fun revelation: Dinosaurs lived on the other side the Galaxy.

a NEW PAPER led the incomparable Dr. Elizabeth Iles (accepted by PASA) quantifies how astronomers might be biased in how they judge galactic bars Turns out that male astronomers are consistently more optimistic than their peers when it comes to measuring length arxiv.org/abs/2511.09908 #astro

Proud of the work I published with @djphysicswebb.bsky.social . Gender Gap in intro physics is eliminated when employing retake exams because women do better on the FIRST try - suggesting exam STAKES (not differences in preparation/understanding) explain gender gap. 🧪 link.aps.org/doi/10.1103/...

This is why we fund scientists to study things like oyster slobber even if you don’t think it sounds important

Cecilia Payne-Gaposchkin ✨ figured out what stars are made of ✨ when she was just 25. 🔭🧪 Her PhD thesis basically established the Harvard astro department — at a time when Harvard didn't officially allow woman students. I wrote this little profile to mark the 100th anniversary of her thesis:

Funding science is very important for a lot of reasons. One of those reasons is that you get papers like this

the semester is starting! here are some of my teaching resources online: intro astronomy animations: zingale.github.io/astro_animat... my computational astrophysics class: zingale.github.io/computationa... my computational hydro text: open-astrophysics-bookshelf.github.io/numerical_ex... #astro

finished project hail mary by andy weir! i loved it! &as someone that doesn’t consume astrophysical fiction ✨ “Do you believe in God? […] I think He was pretty awesome to make relativity a thing […] The faster you go, the less time you experience. It’s like He’s inviting us to explore the universe”

Heard the latest news from the LIGO-Virgo-KAGRA collaboration? We detected the collision of the most massive pair of black holes so far: #GW231123 weighing in at ~137 + ~103 times the mass of the Sun! So to celebrate, here’s a handy chart ✨ Just how chonky are these black holes? 🤔

From Mckenzie Ferrari: Follow along as we zoom through the stars with these hypervelocity stellar survivors and uncover their explosive origins. 🔭✨☄️ astrobites.org/2025/07/22/h...

Today is a big day for us: it's DATA RELEASE DAY!!! And to celebrate our nineteenth data release, we have not one, but two papers for you to read all about our data: we have a DR19 paper (arxiv.org/abs/2507.07093) and an SDSS-V Overview paper (arxiv.org/abs/2507.06989) #DR19

From Caroline von Raesfeld: Today’s bite explores if we’ll be able to find a star that has formed from the gas enriched by only one stellar predecessor, an interesting way to probe what’s actually happening in stellar nucleosynthesis. 🔭✨☄️ astrobites.org/2025/07/08/l...

NASA is erasing much of its progress towards inclusivity — a shameful change that goes against everything astronaut and astrophysicist Sally Ride worked for. My review of the new biopic SALLY, for @nature.com: www.nature.com/articles/d41... 🧪🚀👩‍🚀🏳️‍🌈

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 ⬇️!

How do astronomers decide that objects to observe? You and your students can now map the cosmos with our new card game. We've distributed copies of to several SDSS institutions and anyone can download and print their own copy from the link below voyages.sdss.org/hands-on-act...

in appreciation and solidarity of our national parks, some pictures of my January big bend trip🏜️the beauty, knowledge, and community the parks bring truly cannot be stated enough. and half the park is after dark!🔭

Tired of wondering which atomic lines are in your spectra? You need: *whose line is it anyway?* An interactive tool for identifying atomic spectral lines. 🧪🔭 #stars install: pip install whoseline source: github.com/bmorris3/who...

So glad I decided to get out of my comfort zone to try one of the feeds (Science by @bossett.social). Immediately shown cool stuff like this paper that introduced me to the coolest job ever of "Galactic archaeology". How much do I understand? Maybe 10%. Am I fascinated? 100%.

Although NOAA's page on atmospheric CO2 levels has vanished, you can still get this vital information from Ralph Keeling's team at the Scripps Institution of Oceanography, UC San Diego keelingcurve.ucsd.edu Please follow bsky.app/profile/keel... for updates and share Don't let science be hidden

Have you ever wondered what it looks like when an astronomer starts up a 2.7m telescope for the night? Wonder no more 🔭

🔭 Our Gaia telescope has revealed two mysterious objects: a huge exoplanet & a brown dwarf, both orbiting low-mass stars, a scenario thought to be extremely rare. This is the first time a planet has been discovered by Gaia’s ability to sense wobbling stars 👉 esa.int/Science_Expl...

🔭 don't miss out on our investigation on the Galactic disk, mapping chemical azimuthal variations🗺️

You've probably heard that "we are stardust," but this graphic breaks it down and tells you what kind of stars your dust came from--and which elements didn't come from stars at all. 🧪 svs.gsfc.nasa.gov/13873/

instead of listening to music while working, I now listen to 6+ hour long youtube videos of fantasy (usually throne of glass or recently, fourth wing) ambient noise with soft music, boots walking through snow and/or book pages turning. productivity 📈

hi bluesky! interrupting to show you my first first-author paper that has just been published 🤸‍♀️ iopscience.iop.org/article/10.3... This work is titled [X/Fe] Marks the Spot: Mapping Chemical Azimuthal Variations in the Galactic Disk with APOGEE ( @sdssurveys.bsky.social ) 🗺️ Let's get into it 🧵
