The Northern Lights shining over Great Planets
Inaugural Lecture: Professor Tom Stallard, Northumbria University
In the cold arctic nights, you might be lucky enough to look up at the sky and see the faint green glow of the Northern Lights, aurorae created by the interactions between the Earth’s magnetic field and the Sun’s Solar Wind. But using spacecraft around these planets and some of the largest telescopes in the world, Professor Tom Stallard's work looks out at the Giant Planets (Jupiter, Saturn, Uranus and Neptune) and reveals a wide range of different aurora at these planets. Some appear like the aurora of Earth, but others are powered by volcanic moons, or even weather within the planet itself.
In a fascinating inaugural lecture, Professor Stallard will discuss some of the most exciting observations and what he and fellow researchers hope to see from the James Webb Telescope.
About the Speaker
Professor Tom Stallard is a professor in the department of Mathematics, Physics and Electrical Engineering at Northumbria University. Prior to joining Northumbria in 2022, Professor Stallard was an Associate Professor and an RCUK Fellow at the University of Leicester. An expert in Planetary Sciences, he completed his PhD in Planetary Astronomy in 2001, studying the aurora of Jupiter using ground-based telescopes.
Professor Stallard's research focuses on the delicate interactions observed within the thin and transient layer at the top of giant planet atmospheres - and how this layer is wrought and wrung by two enormous and powerful systems - the underlying atmosphere and the surround magnetic environment. Each of these two systems pushes and pulls at the ionosphere resulting in a complex interaction where each fight for dominance. His observations reveal this layer and, from the twisted interactions he and his colleagues measure, they are beginning to understand how forces are driven from above and beneath - and how this energy exchanges and then flows back up and down into these surrounding regions.
