🌌 DESI DR2 cosmology chains and data products are now public!

🌟 We’re proud to share that the DESI Collaboration has been awarded the 2026 Lancelot M. Berkeley–New York Community Trust Prize by the American Astronomical Society (AAS) — read more on the AAS website aas.org/press/desi-c... 🎉

🕳️✨ What if black holes don’t just swallow matter… but transform it into dark energy?

🚨 DESI High is back! 🚀🌌 High school students in Mexico & Spain recently explored the universe using real data from the Dark Energy Spectroscopic Instrument. 🔭💻

The @desisurvey.bsky.social makes a precise 3D map of galaxies to explore 11 billion years of cosmic history. Saul Perlmutter, Berkeley Lab scientist and Nobel laureate, shares what the experiment’s recent #DarkEnergy results mean for our big picture of the universe. 🎧 via @theguardian.com ⬇️

DESI 2025 - Cosmology Results from DR2 BAO (Garcia-Quintero & Martini) 😍☄️🔭🚀 youtu.be/YiRaDtslycE?... via YouTube with @justshaun.bsky.social 🎙️

Check out the new key papers and supporting papers available here: data.desi.lbl.gov/doc/papers/

🔊 New BAO analysis from the 3-year observations (DR2). Long story short, as follows. 1. DESI alone is consistent with LCDM. 👉 Boring 2. DESI and Planck have a 2.3 discrepancy in Ωm-H0rd plane. 👉Interesting.

DESI's DR2 BAO results are out!! TL;DR... 1/n @desisurvey.bsky.social

This is starting to look believable (to me at least 😅) *Something* is certainly going on... Great work @desisurvey.bsky.social! youtu.be/YiRaDtslycE

🔭👀 New results from the @desisurvey.bsky.social strengthen hints that #DarkEnergy might evolve. News release ⬇️ newscenter.lbl.gov/2025/03/19/n... #Space #arXiv 🧪

JUST RELEASED: DESI DR1 & BAO RESULTS FROM DR2🌌

🚨 BIG NEWS ALERT! 🚨 We’re just 24 HOURS AWAY from a MAJOR DESI release! 🌉🔭 Tomorrow at 3 PM PT, DESI is unveiling DR1, our first official Data Release—the largest dataset of its kind, packed with information on 18.7 million galaxies, quasars, and stars! But that’s not all…

In its quest to make precision cosmological measurements, DESI uses a process called “blinding” in its analysis methodology in order to avoid the inaccuracies that can arise from confirmation bias. This process was especially important for DESI’s latest results, which will be revealed on March 19🚀

You’ve seen BaoBan proudly riding atop the Kitt Peak float at the Tohono O’odham Nation Rodeo Parade, but have you heard the full story behind him? 🧵...

DESI’s ambassador, BaoBan, made a grand appearance at the 2025 Tohono O’odham Nation Rodeo Parade, perched high atop the Kitt Peak National Observatory (KPNO) float! 🌟

Professor Mustapha Ishak from University of Texas at Dallas, a senior member of the DESI collaboration, explains what our survey aims to achieve: mapping the positions and velocities of millions of galaxies 🌃 With this vast dataset, DESI will trace the universe's expansion history 💪🚀

Non il cadavere di Laura Palmer bensì migliaia di buchi neri – fra i quali centinaia di rari buchi neri di taglia ‘M’ – sono stati scoperti da @desisurvey.bsky.social scrutando il cielo dalla tranquilla località montana di Kitt Peak, in Arizona. Il servizio video su MediaInaf Tv.

Hello, world! 👋🦋 We are excited to announce our new Bluesky account. We are the Dark Energy Spectroscopic Instrument (DESI), a scientific collaboration that has measured the effects of dark energy on the expansion of the universe with unprecedented precision! To learn more, visit: www.desi.lbl.gov
