Bedtime Astronomy

Astronomers analyzing data from the Vera C. Rubin Observatory have identified a massive icy object beyond Neptune that could be a new dwarf planet.

Provisionally named 2026 ED138, the distant world remained hidden among crowded background stars until advanced search algorithms revealed its movement across a decade of archival images. If future observations confirm its shape, it could become another recognized member of the solar system’s dwarf planet family.
