The NSF–DOE Vera C. Rubin Observatory has not finished its first year of science operations, yet astronomers combing through its test images have already found two previously unknown objects orbiting the Milky Way. One, named Aquarius IV, appears to be an ultra-faint dwarf galaxy. The other, Rubin-GC1, is a small star cluster tucked behind thick dust on the far side of our galaxy, according to a University of Washington announcement released Nov. 5.
