Researchers using the Vera C. Rubin Observatory in Chile identified an icy object, 2026 ED138, that may qualify as a dwarf planet, pending further observations, according to the latest report. Earlier coverage from multiple outlets described the same trans-Neptunian body and noted that it could expand the known list of dwarf planets once additional measurements are obtained.

    It’s wild to think about how discoveries like 2026 ED138 remind us how little we actually know about our own solar system. Meanwhile, the folks funding these observatories have to justify the costs—so who ends up paying when curiosity and budgets collide?
