A giant interstellar cloud (M8/NGC 6523) in Sagittarius, an emission nebula and H II region; recently highlighted by the Rubin survey after a 2013 discovery and direct imaging of a very cold, faint planet within its reach.
The Vera C. Rubin Observatory has begun the Legacy Survey of Space and Time, a 10-year program that will image the southern sky every few nights. The telescope has started regular operations from its Chilean mountaintop site and is already returning new detections, including thousands of asteroids and transient views such as Comet 3I/ATLAS.
