Near-Earth space is filled with energetic ions and electrons of multi-MeV energy, which can damage sensitive satellite components and harm humans in space. The energy comes from the Sun’s outbursts of plasmas, the dynamic solar wind, but it is focused and amplified in Earth’s magnetized space environment, the magnetosphere. The tug of war between the solar wind and our magnetized planet drives the dynamic auroras, Earth’s radiation belts, and affects our atmosphere. Space weather is a major field of study for space agencies around the world. Modeling and predicting radiation particle fluxes is still in its infancy.

Electromagnetic radiation observed from various cosmic sources is intrinsically polarized, with its polarization depending on the geometry and, specifically, the asymmetry of the source. Polarimetry offers an independent method for exploring the physics and astrophysics of cosmic objects, complementing traditional techniques such as imaging, spectroscopy, and timing. It enables us to determine the geometry of otherwise unresolved sources—for instance, identifying the orientation of the symmetry axis of a source or the magnetic field in the sky—providing insights that no other technique can offer.
Online Seminar with Tilman Spohn (DLR, Berlin, Germany)
ISSI’s Game Changers online seminar series was launched during the first Covid-19-related lockdown in summer 2020 to help keep the community together. Up until this 100th webinar, the series has covered a wide range of topics, from climate change on Earth to life in the universe and the Big Bang.
Online Seminar with Roberto Maiolino (Cambridge University, UK)
The James Webb Space Telescope is revolutionising most areas of astrophysics. One of the most exciting and puzzling findings has been the discovery of a large population of massive black holes within the first billion years after the Big Bang.
