Aurora in the Solar System: What they can teach us
The deposition of solar and auroral particle energy in atmospheres of bodies across the Solar System
Marina Galand is Professor in Planetary Science at Imperial College London, and has been exploring the deposition of solar and auroral particle energy in atmospheres of bodies throughout the Solar System and beyond, in close link with international space missions, such as Cassini and Rosetta.
In her inaugural lecture she will discuss how this energy is deposited in planetary atmospheres, will highlight the key role played by the plasma layer produced, and will explore how auroral emissions can be used to infer information on the energy source. She will illustrate her lecture with examples taken at several Solar System bodies, including Earth, Jupiter’s moon Ganymede, and comet 67P.

Data from NASA instruments aboard the ESA (European Space Agency) Rosetta mission have helped reveal that comet 67P/Churyumov-Gerasimenko has its own far-ultraviolet aurora.

'Northern lights' surrounding Rosetta's famous comet
Astronomers find "northern lights" surrounding Rosetta's famous comet for the first time
Astronomers have previously spotted glowing auroras surrounding planets, as well as Jupiter's moons — but now, for the first time, they've found the dancing light show on a comet.
