This fifth Europlanet Juice webinar consists of three talks:

00:03:40 Davide Grassi, planetary scientist and Co-I of the Moon and Jupiter Imaging Spectrometer (MAJIS) at INAF in Rome, Italy, speaks about what can be expected from Jupiter observations with MAJIS and how these are being planned.

00:19:22 Patrick Irwin, planetary scientist and Co-I of MAJIS at the University of Oxford in the UK presents his latest results of observations done with the VLT/MUSE instrument and how ammonia and cloud level maps can be extracted from them.

00:37:37 This is in close connection to the results that by Steven Hill independent scientist in Colorado, USA, presents. He uses commercial-level equipment to observe Jupiter and extract information about the ammonia and cloud levels across the planet.

00:57:40 Q&A
