Giant 3.2-Gigapixel Eye to Map Billions of Galaxies Each Night

The Vera C. Rubin Observatory’s LSST camera—the largest digital camera ever built—uses a 3,200-megapixel (3.2 gigapixel) sensor array spread across 1.57 meters, with 189 ultra-clean CCDs cooled to -100°C to image the southern sky. It captures wide, fast exposures that sweep about seven times the width of a full moon, producing roughly 10 terabytes of data per night and aiming to catalog billions of galaxies and stars over its 10-year Legacy Survey, enabling unprecedented wide-field, time-domain astronomy and detailed structure in star-forming regions.

Vera Rubin Observatory Poised to Probe Planet 9’s Existence

New statistical work strengthens the case for a hidden ninth planet beyond Neptune: distant objects show non-random clustering that simulations including Planet 9 reproduce, while models without it do not. The exact location remains unknown, but the Vera Rubin Observatory’s first observations are expected to provide a decisive test of Planet 9’s existence.

Tiny Space Rocks, Big Risks: The Decameter Asteroid Threat

MIT researchers warn that decameter-scale asteroids (tens of meters across) strike Earth every few decades, potentially causing 8–10 megaton airbursts, disrupting satellites and possibly triggering the Kessler debris cascade; detection is hard due to low reflectivity, but JWST has aided tracking and Vera Rubin will find more, while MIT is building a follow-up telescope network—though there is currently no global framework to defend against such threats.

Bus-sized asteroid 2026 EG1 to skim past Earth in a near-miss

A newly discovered bus-sized asteroid named 2026 EG1, about 10–22 meters across, will pass within about 1 lunar distance of Earth late on March 12 (closest approach around 11:27 p.m. EDT / 0327 GMT March 13), traveling at roughly 21,513 mph. Discovered March 8, it poses no threat; NASA tracks thousands of near-Earth objects and continues defense planning with help from observatories like Vera Rubin.

Rubin Observatory Unleashes Real-Time Sky Alerts, 800,000 Notifications Overnight

The Vera C. Rubin Observatory kicked off its real‑time alert system, dispatching 800,000 sky-change notifications to researchers worldwide in its first run. The alerts flagged events like supernovae, asteroids, variable stars, and active galactic nuclei, and are powered by the Alert Production Pipeline designed to scale up to about 7 million alerts per night, enabling rapid follow‑up observations as the Legacy Survey of Space and Time proceeds.
