Scientists puzzled by possible atmosphere on distant dwarf world beyond Pluto

Astronomers have identified a tiny celestial body beyond Pluto. New observations suggest the object could be surrounded by an atmosphere. The finding challenges expectations for such distant, icy worlds. Scientists admit they lack a clear explanation for the atmospheric presence. The object’s composition and temperature add to the mystery. Researchers are planning follow‑up observations to confirm the feature. If confirmed, the atmosphere would reshape theories of outer‑solar‑system bodies. The discovery underscores how much remains unknown about distant worlds.
