Astronomers using the #JamesWebbTelescope #JWST have found water vapor, carbon dioxide, and methane on planet K2-18b
2.6x Earth radius, in the habitable zone (liquid water possible), 124 ly away
The cool part:
They also found DMS. Dimethyl Sulfide (probably, the signal is weak, they need to confirm)
you know DMS as "the smell of the sea"
We don't know of any geochemical processes that make DMS
The only process we know of that makes DMS, is life
