Had a brilliant time discussing the claims that biosignature gases may have been found in the atmosphere of exoplanet K2-18b with exoplanetary scientist @distantworlds.space
These claims appear to be very premature.

In summary, the paper engages in statistical hacking to hit the magical '3σ'.
Now here's where the bad science communication comes in.
The University of Cambridge put out a press release making bold claims about a detection of possible biosignatures.

Strongest hints yet of biological activity outside the solar system
Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.

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).
