What it means

The Vera C. 's early data has revealed two previously unknown satellite galaxies of the Milky Way — likely faint dwarf galaxies that were too dim for earlier surveys. Scientists expect the ongoing Legacy Survey of Space and Time (LSST) to uncover hundreds more such hidden companions, dramatically filling in the census of our Galaxy's small neighbors.

Accuracy & sourcesSourced

The claim originates from a Science Daily article citing a study (likely published or submitted to a peer-reviewed journal) that used early Rubin Observatory data. Science Daily is a reputable secondary source, but without direct access to the primary paper, the specific numbers and details should be treated as reasonably solid but not independently confirmed by this summary.

How new

Genuinely new, as no recirculation year is indicated and the discovery appears to be based on recent data from the Rubin Observatory's survey.
