The open star cluster Messier 21 as imaged by the Vera C. Rubin Observatory

Located near the Trifid Nebula, Messier 21 is relatively young and tightly packed with small, dim stars.

Vera Rubin Observatory Reveals Telescope’s First Images of Galaxies, Nebulas and Asteroids

Scenes of nebulas in the Milky Way, a cluster of galaxies and thousands of new asteroids are a teaser of how the U.S.-funded observatory on a mountain in Chile will transform astronomy.

A Swarm of New Asteroids (Video-EN)

In about 10 hours of observations, NSF–DOE Vera C. Rubin Observatory discovered 2104 never-before-seen asteroids in our Solar System, including seven near-Earth asteroids (which pose no danger). Annually, about 20,000 asteroids are discovered in total by all other ground and space-based observatories. Rubin Observatory alone will discover millions of new asteroids within the first two years of the Legacy Survey of Space and Time. Rubin will also be the most effective observatory at spotting interstellar objects passing through the Solar System.
