Discussion panel - Exoplanet K2-18b: the search for biosignaturesB2.04/5 (science concourse) and on TeamsK2-18b is an exoplanet a few times the size of Earth, orbiting in the habitable zone of a red dwarf star. As such, it is a very interesting target for studies of exoplanet atmospheres and habitability. Earlier this year, a new study tentatively detected dimethyl sulphide (DMS), a possible biosignature, in K2-18b's atmosphere. The study sparked extensive debate in the academic literature and in public media, and the claimed detection remains controversial. In this panel discussion, experts from the 91¸£Àû will present their work on aspects of science relevant to the K2-18b case, and discuss how the way we communicate resarch can influence public opinion. |
