In the final of three mini-exocasts we will release this month, we cover some of the notable happenings in exoplanet science over the past month. On this episode we cover new planets from the TESS mission, a novel technique for detecting exoplanets using radio emission, and the end of the very productive KELT survey after 17 years. We also revisit K2-18b, which hit the exoplanet headlines last year after water vapour was definitively detected in
