Why does the length of a day on Saturn change over time?

The length of a day on Saturn has been changing constantly ever since the first sophisticated proxy measurements were taken by the Voyager I and II spacecraft back in the 1980s and then later by the NASA Cassini spacecraft in the early 2000s. Using ground-based observations of Saturn's infrared northern aurorae, we carried out our own unique experiment to try and detect the hypothesised "twin-vortex" mechanism in the planet's atmosphere that is suggested to drive the changes in Saturn's rotation rate. In this talk, we'll present the results of this experiment as well as a staggering discovery that answered one of the longest standing questions in planetary science.

Speaker bio:

Nahid was born in Oldham but grew up in Leicester which is where he attended primary school all the way through to university, graduating with an MPhys Physics with Astrophysics degree in 2017 before starting his PhD in planetary science, which he is set to finish in 2022. His primary research focus is on the infrared aurorae of the gas giant planets and his work involves observing  the aurorae of Jupiter and Saturn using major ground-based telescopes and then investigating the impact of these emissions on the wider local planetary environments at large. He led the recent study which addressed why Saturn's rotation rate is subject to change over the course of several years. He also supports the foundation year teaching in physics and maths at the University of Leicester and is a keen public outreach enthusiast which led him to holding paid positions at both the Royal Observatory Greenwich in London and the National Space Centre in Leicester.
