In the hunt for alien life, this planet just became a top suspect

The mixture of gasses measured in exoplanet K2-18 b suggests it may have a global ocean beneath a hydrogen-rich atmosphere—and astronomers even spotted a tantalizing, though unconfirmed, sign of life.

Early 2024, JWST's infrared instrumentation will scan for dimethyl sulfide, a biomarker for life.

Will resolve YES if there is statistically conclusive evidence. Resolves NO if no DMS is not conclusively detected.

This question is managed and resolved by Manifold.

If anyone wants to buy yes, hit me up and I can provide liquidity. Don't want to leave limit orders up incase the news comes out against me.

I was pretty excited by this, but news media didn't mention that the DMS result is only 1 sigma, so 15% of planets without DMS would look more convincing than K2-18b.
