Vera C. Rubin Observatory Uncovers Two Previously Unknown Companions of the Milky Way

The recently completed NSF-DOE Vera C. Rubin Observatory has made its first discoveries, revealing two elusive objects that had previously escaped detection: an extremely faint galaxy located 355,000 light-years away and a star cluster hidden behind cosmic dust. These initial observations, covering only 7% of the night sky, demonstrate the observatory's capability to find some of the faintest members of our galactic neighborhood. Scientists anticipate that hundreds more satellite galaxies may still be undiscovered around the Milky Way, and the Rubin Observatory is expected to play a crucial role in bringing them into view.
