DESI unveils the largest 3D map of the cosmos, spanning ~75% of the sky with 5.6 trillion pixels and ~4 billion objects; a free Legacy Imaging Surveys viewer lets the public explore the data while scientists study dark energy, with more results and AI-assisted analysis planned for 2027.
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.
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.
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.
NASA's SPHEREx telescope has completed its first comprehensive infrared map of the entire sky, capturing 102 different wavelength images that provide valuable data for understanding the universe's origins and evolution, with more scans planned during its primary two-year mission.
The Vera C. Rubin Observatory in Chile, named after astrophysicist Vera Rubin, captures stunning views of the Milky Way and is set to conduct a decade-long survey of the night sky, collecting vast amounts of data on billions of celestial objects to better understand the universe.
A study analyzing historical sky survey data found small but significant associations between short-lived star-like transients, nuclear weapons testing, and reports of unidentified aerial phenomena (UAP), suggesting potential links that warrant further investigation.
The Vera C. Rubin Observatory has started a decade-long sky survey using its advanced telescope and the world's largest digital camera, capturing rapid star scans and aiming to study cosmic phenomena like dark matter and near-Earth objects.
The NSF–DOE Vera C. Rubin Observatory in Chile has unveiled its first images, showcasing its powerful wide-field imaging capabilities designed to survey the southern sky extensively, identify countless celestial objects, and advance our understanding of cosmic phenomena like dark matter and dark energy, while generating vast amounts of data for scientific research.
NASA's newest space telescope, SPHEREx, launched from Vandenberg and now in orbit, has begun capturing and publicly releasing images of the universe, using 102 wavelengths of infrared light to study cosmic phenomena, including water and organic molecules in the Milky Way, with plans to complete multiple sky surveys over its 25-month mission.
The Vera C. Rubin Observatory has released its first stunning images, showcasing its advanced capabilities to capture high-resolution, time-lapse images of the night sky. Designed to survey the entire southern sky over ten years, it will generate massive amounts of data, enabling the discovery of new celestial objects and phenomena, including asteroids, supernovae, and potentially unknown planets, revolutionizing astronomical research.
The Vera Rubin Observatory in Chile features the world's largest digital camera, capable of capturing detailed images of the night sky and generating 20 terabytes of data nightly, aiming to catalog billions of celestial objects and monitor changes in the sky over the next decade.
The Vera C. Rubin Observatory in Chile is set to reveal its first images on June 23, 2025, marking a new era in astronomy with its advanced 3,200-megapixel camera and 10-year sky survey, capturing unprecedented data and potentially groundbreaking discoveries, with live watch parties available worldwide.
ESA's new Flyeye telescope has successfully achieved 'first light,' marking the start of its mission to automatically survey the sky for near-Earth asteroids and comets, using a wide field of view inspired by an insect's eye to enhance early detection and planetary defense efforts.
