Webinar with Jean Lilensten (Institut de Planétologie et d’Astrophysique de Grenoble, France)
The Shining Earth: The Polar Lights
The aurora borealis (to the north, and australis to the south of the Earth) are the most spectacular phenomena of a chain that connects the planet’s upper atmosphere to the solar activity. In this lecture, the speaker addresses the questions they raise: What solar origin ? What interaction between the solar wind and the space environment ? How are they formed? What are they witnessing? Do they exist elsewhere than on Earth? What research is still being done on auroras?
