DESI Wraps Its First Major 3D Map and Expands the Cosmic Survey

DESI finished its originally planned five-year survey ahead of schedule, delivering the largest high-resolution 3D map of the universe by observing more than 47 million galaxies and quasars and 20 million nearby stars. The endeavor will extend the map to about 17,000 square degrees by 2028 to improve studies of dark energy and dark matter, with first full five-year results expected in 2027. The effort overcame challenges from COVID-19, the 2022 Kitt Peak fire, and weather, and will continue processing the data and expanding observations to new galaxy populations as DESI pushes deeper into cosmic history.

Radio Sky Census Unveils 13.7 Million Hidden Objects

Scientists released the LOFAR DR3 dataset—the largest radio sky survey to date—mapping about 13.7 million radio-emitting objects across 88% of the northern sky, drawn from 18.6 petabytes of data processed with Europe’s supercomputers; the survey reveals extreme phenomena like black-hole jets and distant active galaxies, and demonstrates the massive data-handling required to stitch signals from 70,000 antennas, setting the stage for future SKA projects and widespread follow-up studies.

Cosmic census begins: Rubin Observatory to map 20 billion galaxies over a decade

Over the next decade, the Vera C. Rubin Observatory will image the southern sky in unprecedented detail, cataloging about 6 million asteroids, 17 billion stars, and 20 billion galaxies. With roughly 10 terabytes of data per night, the Legacy Survey of Space and Time aims to uncover the nature of dark matter and dark energy, while a network of community brokers processes detections in near real time and the public can participate as citizen scientists via online tools and data releases.
