Rubin Observatory discovers two hidden companions of the Milky Way. Hundreds more may be waiting
The Vera C Rubin Observatory has found two new companions to the Milky Way galaxy in preliminary observations that covered only a small portion of the sky. One is an extremely faint galaxy, while the other is a star cluster hidden behind dust and gas. These discoveries suggest there may be many more undiscovered satellite galaxies.
Why it's good news: It could lead to the discovery of hundreds more unknown celestial bodies in the universe.
