We are devastated to learn that Patrick Gaulme ((@patrickgaulme.bsky.social) has passed away. He had an illustrious career in planetary and red giant seismology and was an Astronomer for SDSS-IV. He was awarded Architect status in SDSS-IV for all of his work on observations.

Thank you!
I remember the first SDSS data release. Hard to appreciate how transformative it was, both for the data and how they made it publicly available. Awesome to see them keep trucking. Congratulations to all involved!
Yesterday we released our nineteenth data release into the wild: www.sdss.org/dr19, let’s now take a closer look on what is in this data release. #DR19

With the release of DR19 of @sdssurveys.bsky.social we published a suite of tutorials to help astronomers use the data. I’d like to highlight two tutorials that are a little different and are targeted at introductory astronomy undergrad classes. 1/4

DR19 also includes nine brand-new Value Added Catalogs (VACs). These catalogs are based on SDSS-V spectra and data products, and produced by SDSS-V collaboration members. Find these 9, and the 67 VACs from earlier data releases all here: www.sdss.org/dr19/data_ac... #DR19

@blackholemapper.bsky.social had already released a few spectra in DR18, but they are going all out for DR19, with lots of galaxy and quasar spectra #DR19

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

How do astronomers decide that objects to observe? You and your students can now map the cosmos with our new card game.

Want to hear about how SDSS scientists are studying huge bubbles and shockwaves in the Milky Way and beyond?

Then come to our public talk next Wednesday evening at Haus der Astronomie in Heidelberg. The talk will be in German
Tom Herbst und Niv Drory zeigen euch am 4. Juni um 19 Uhr am HdA wie man die riesigen Blasen und Schockwellen, die von heißen Sternen in unserer Milchstraße und ihren Begleitgalaxien erzeugt werden kartiert. Tickets erhaltet ihr online unter ztix.de/hp/events/27... und an der Abendkasse 🔭

We love to see it Alex! Congratulations!

Because nucleosynthesis is still spectacular! #barbenheimerstar
Still not quite believing it but feeling very fortunate to be among the 2025 Sloan Research Fellow cohort!
🎉Congrats to the 126 early-career scientists who have been awarded a Sloan Research Fellowship this year! These exceptional scholars are drawn from 51 institutions across the US and Canada, and represent the next generation of groundbreaking researchers. sloan.org/fellowships/...

If you have a chance to see the incredible @emilyjogriffith.bsky.social give a Planetarium talk -- DO IT!!!!

She is one of our fearless leaders in SDSS working toward understanding our Milky Way!
Excited to be giving a public planetarium talk at Embry Riddle University tonight! Love showing off the @sdssurveys.bsky.social data :) Sold out show!!

Happy Valentine's Day to everyone who loves stars and sees nothing but 💗 in their CMDs, HRDs, MHDs, PhDs, etc.

The return-on-investment for the SDSS surveys is truly extraordinary.

It is mid-scale, it is efficient, it is open, it is reasonable, it is diverse, it is inclusive.

All of the data is returned to all of humanity for the benefit all of humanity.

Join us!

Love this account, especially when they show the picture of a galaxy that we took 🔭📷
A smooth galaxy, observed with the Apache Point 2.5m Telescope in the SDSS survey.

It is at redshift 0.090 (lookback time 1.22 billion years) with coordinates (193.67645, 32.97523).

45 volunteers classified this galaxy in Galaxy Zoo 2.
