¿Seguirá el cometa interestelar 3I/ATLAS emitiendo metano detectable hasta el 31 de julio de 2026?

Por qué: - Premise (Sky at Night Magazine, 2026-06-02): It reports that JWST “directly detected methane gas” at comet 3I/ATLAS, the first ever direct methane detection in an interstellar object. → Direct detection by spectroscopy means the comet exhibited detectable CH4 emission. - Premise (Astrobiology.com, 2026-06-02): Describes JWST/MIRI spectral observations mapping gases around 3I/ATLAS and states “for the first time on an interstellar visitor, Webb directly detected methane gas,” with spectra labeling CH4 features escaping from the comet. → Confirms methane emission was observed spectroscopically. - Inference: Once methane emission from 3I/ATLAS has been directly detected and reported (June 2026), it remains true on or after July 31, 2026 that the comet showed detectable CH4 emission. → Therefore, as of the asked date, the answer is YES.
