Giant planet astronomy in the Solar System and beyond" In this talk I will give an update on my work using ground-based telescopes to study the upper atmospheres of Jupiter, Saturn and an exoplanet. At Jupiter we are exploring a planetary-scale hot feature which seems to be leaving the auroral region -- we plan to make a paper which talks all about it in FY2021/22. At Saturn I will report that we have not been able to detect H3O+, a type of water molecule, in Saturn's upper atmosphere, but detail some new ways we might be able to detect it using the SOFIA telescope (a telescope which is on a plane, run by NASA). We have an upcoming exoplanet observation in April which I will also discuss. Finally, I was offered the chance to write a review paper on the remote sensing of Jupiter, Saturn, Uranus and Neptune upper atmospheres, so I will discuss that as well.
