Rubin Observatory discovers two hidden companions of the Milky Way. Hundreds more may be waiting

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.

The Vera Rubin Has Found Two More of the Milky Way's Dim Satellites

The Vera Rubin Observatory has detected two more of the Milky Ways' dim, hard to see satellites. One is an ultra-faint dwarf galaxy, and one is a globular cluster. Each one is a missing piece of the puzzle in the Milky Way's merger history. By finding more of these satellites, our understanding of galaxy growth, and the role dark matter plays in it, will improve.

What Vera Rubin Observatory’s first new dwarf planet means

Back in 2006, the International Astronomical Union controversially demoted Pluto . This composite image of Pluto and its largest moon, Charon, was based on photographs taken by the New Horizons mission as it flew by the Plutonian planetary system back in 2015. Charon’s appearance is vastly different from Pluto’s, but both bodies are shown with the correct relative size and albedo. The surface features on Pluto show evidence of recent changes, indicating that the next time we visit Pluto to image it at this level of precision, it may exhibit a remarkably different appearance.
