Thanks to all who came out to the 2026 Owens Valley Radio Observatory (OVRO) Open House this past Saturday. It was a joy to meet all of the visitors and explore the future of DSA together. #Astronomy #OVROOpenHouse

School is officially back in session, which means the DSA is also back in the classroom. Dr. Katie Jameson and Dr. Cameron Hummels returned to 5th Grade classrooms.

What exactly are FRBs, and why do we want to observe them? Allow Professor of Astronomy Vikram Ravi to explain. 📡 deepsynoptic.org/

Fast radio bursts (FRBs) can be used to map out the distribution of matter in our universe. The Caltech Deep Synoptic Array (DSA) will be able to find tens of thousands of FRBs. Listen to Professor of Astronomy Vikram Ravi to explain more and why that is so exciting.

For the second year running, the DSA sponsored the annual Wine Walk fundraiser for the Boys and Girls Club of Truckee Meadows serving White Pine County. DSA Project Manager, Dr. Katie Jameson, had a wonderful time and won some great prizes! 🖼️ 🥏 🍞

Our Special Session at #AAS248 was a great success‼️ We highlighted the wide range of science that data from the DSA will enhance: Multimessenger Astronomy, the Dynamic Radio Sky, Our Cosmic History (deep HI and continuum imaging), as well as the Dark Sector & Strong Gravity.

Need a pick-me-up while you’re at #AAS248? Stop by the DSA booth in the expo hall for a bag of custom-roasted DSA coffee beans or one of our new camp mugs! ☕

The NNRY Star Train in Ely is a unique way to enjoy the dark skies. And it was just featured in @nytimes! For the past two years, @CaltechAstro and the DSA provided professional astronomer volunteers that helped passengers learn more about the night sky: bit.ly/4uW1vl8

The City of Ely is the first in the state to resolutely celebrate Nevada's dark skies! Just another reason we are proud to be developing the DSA in Ely and White Pine County. Their commitment to keeping the skies dark and star-studded is unparalleled. 📸: Kelly Carroll & Ed Ruiz

DSA Lead Project Manager, Dr. Katie Jameson, attended "On Target NV", an event hosted by Northeastern Nevada Regional Development Authority (NNRDA) in Elko, NV. Not only did Katie drop in on the event, but she was also a guest on the "New Business & Game Changers" panel.

The first of @CaltechAstro and DSA’s Science Fiction Film Series featured free screenings of “Interstellar” and “WALL-E”, each with a short intro on the real science behind the movies. The day also featured a visit to the 5th grade class in McGill.

It’s been an exciting #AAS247 as the DSA was announced to be part of the Schmidt Observatory System and we can share that we are funded for construction by Schmidt Sciences! We are looking forward to opening up the dynamic radio sky to the worldwide astronomy community. 🔭
