中文摘要：
The Vera C. Rubin Observatory has already uncovered two previously unknown companions of the Milky Way using preliminary observations covering just 7% of the night sky. The discoveries include an extremely faint galaxy 355,000 light-years away and a star cluster hidden behind cosmic dust. Scientists suspect hundreds of additional satellite galaxies remain undiscovered, and Rubin's powerful telescope could finally bring them into view.
