Gemini and JWST Observe Icy Centaur 450P/LONEOS Activity

Astronomers used the Gemini North telescope and the James Webb Space Telescope to observe Centaur 450P/LONEOS. They detected a returning coma, carbon-dioxide gas, and increased dust production, providing real-time data on its composition and activity. These observations offer valuable insights into Centaurs, which are thought to preserve material from the early Solar System.
