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!

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

@localvolumemapper.bsky.social is an integral-field spectroscopic survey of the Milky Way, the Magellanic Clouds, and other Local Volume Galaxies. Read more about what they are doing here: www.sdss.org/dr19/lvm/abo... #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

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

🔭LVM is a robotic SDSS facility at Las Campanas Observatory in Chile’s Atacama Desert mapping the interstellar medium of the Milky Way and nearby galaxies✨ Get an eye on LVM with our image gallery: www.sdss.org/science/imag...

The SDSS-V DR19 is now online at www.sdss.org 🎉 For the first time, LVM data is released. Get a sneak peak into LVM data and download our amazing LVM tile of the Helix Nebula!✨ A tutorial showing how to access, read in, and work with the data is available here: www.sdss.org/dr19/lvm/tut... 💻

We have a data release! Check out sdss.org/dr19 for all the data that just became publicly available with our 19th data release #DR19

Discover the ✨amazing✨ possibilities of LVM in this image of IC 434 in the Orion constellation, featuring the Horsehead Nebula emerging on the left (credit: ui.adsabs.harvard.edu/abs/2024A%26...). Find more information here: sdss.org/robotic-tele...

So many webpages........

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. 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...

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

We love to see it Alex! Congratulations! Because nucleosynthesis is still spectacular! #barbenheimerstar

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!

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 story we ❤️about how exploring the Universe can re-ignite passion. And we don't mind that it's about looking at our white dwarf spectra in @jjhermes.bsky.social group 🤩🔭 www.bu.edu/articles/202...

Go, Stroopwafel, go!

#DocuOrca is still going strong, though this is the last day 🔭

🔭

We had a wonderful time had on the boat watching whales and sea lions. A lovely break from documenting Data Release #19 for those who went (& thx to those who continued to document 📜) p.s. the Orca has now been named Stroopwafel, in honor of the pod we saw that was led by Flapjack 🔭

ORCAS Which we documented

#DocuOrca is going whale watching

Composite photo of many of the folks doing #DocuOrca this week for Data Release 19. 🔭 Bsky'ers include @johndonor3.bsky.social @smorrison.bsky.social @amweijmans.bsky.social @thejunaverse.bsky.social @jajohnson.bsky.social working for @blackholemapper.bsky.social and @milkywaymapper.bsky.social

Mount Ranier looking lovely today presiding over DocuOrca. Have paused documenting about radial velocities to document this 🔭

Update on Day 3 of our Data Release 19 documentation festival #DocuOrca in Seattle Number of orcas seen: 1 (knitted, incomplete) 🔭

AND THEN the plate was used as a sled! 8/10 -- a little stiff over the bumps 🔭

🚨🚨🚨🚨 A new use for SDSS plates has been found! UWash crew closing Manastash Ridge Observatory for the winter got stuck in the snow & used an SDSS plate to carry vital equipment. 🔭

Update on our Data Release 19 documentation festival #DocuOrca on its second day Number of orcas seen: 0 Number of Mt. Raniers seen: 1 Number of Mike Blantons seen: 1 Number of tutorials on GitHub: 8 Onward and upward 🔭

The LVM data is going to be lit! …..by ionizing radiation …..from nearby O and B stars 🔭

We can see Mt Rainer from our tower room. In Seattle in December! #DocuOrca

Like armies, we document on our stomachs #DocuOrca 🔭

We are starting #DocuOrca off right… with stroopwafels! 🔭

We are starting #DocuOrca to work on Data Release 19 documentation in Seattle 🔭

We are busy at DocuChili, working hard on Data Release 19 in Las Cruces, MN, hosted by NMSU. We are also busy winning trivia night thanks to certain people's excellent knowledge of 80s and 90s sci-fi and cult movies.

Now we have many interesting talks on removing instrumental effects from the data and actually measuring the things we want to. 🤩

This morning at the collaboration meeting, we had a wonderful talk by Keith Hawkins on metals varying: azimuthally in the disk and in the atmospheres of white dwarfs 🔭

Lots of updates about AGN studies in the first contributed talk session. Andrea Merloni, however, is sliding in a galaxy cluster or two... 🔭

Jon Trump is explaining why supermassive black holes are so interesting and how we can measure their masses using reverberation mapping, a key program in SDSS-V. 30 years of RM campaigns ~ 80 supermassive BH studied BHM-RM -- simultaneous echo mapping of 380 quasars! 🔭

Joe Burchett on Black Hole Mapper (@blackholemapper.bsky.social ), courageously representing all the science AND leading the commissioning effort on BOSS. 🔭

Andrew Tkachenko for the Milky Way Mapper @milkywaymapper.bsky.social all about the Best. Galaxy. Ever 🌌🔭🤩 > 1 million unique objects observed with APOGEE and BOSS -- covering the HR diagram. No star can hide from us.

Local Volume Mapper is awesome! See how stars form and then affect their surroundings! Evelyn Johnston is talking about bringing this enclosure and instrument to life 🔭

Keith Hawkins, our fearless spokesperson, talking about our collaboration policies, so we can all work well together. Very fond of the "anyone can work on anything, provided you let people know that you are doing it..." plan
