A new, thorough reanalysis of the data that led to claims of biosignatures on K2-18b from @luiswel.bsky.social & friends - a nicely written lesson on why this stuff is hard. They find no significant evidence for DMS, the gas the Cambridge team claimed to have found. arxiv.org/abs/2504.21788
The Challenges of Detecting Gases in Exoplanet Atmospheres
Claims of detections of gases in exoplanet atmospheres often rely on comparisons between models including and excluding specific chemical species. However, the space of molecular combinations availabl...

Nice to see this research note on K2-18b from @astrojake.bsky.social, which demonstrates that a flat line (i.e. no spectral features) is a good fit to the MIRI data.

K2-18b is back in the news, now with a bold claim that biosignature molecules (DMS and/or DMDS) have been 'detected at 3σ'.
Most exoplanet astronomers are extremely sceptical about these claims, let's see why (1/n).

Promising hints of life found on distant planet K2-18b
Scientists find new but tentative evidence that a faraway world orbiting another star may be home to life.
