Aging telescope detects atmosphere on distant trans‑Neptunian object

Researchers using an older telescope observed a distant object beyond Neptune. The instrument detected signs of a thin gaseous envelope. The object is classified as a trans‑Neptunian body. The finding suggests the object retains an atmosphere despite its distance. The discovery was reported by Asahi Shimbun. No further details on composition or size were provided. Scientists plan to follow up with additional observations. The result could inform models of outer‑solar‑system bodies.
