Martin Archer

Hi Martin. Thank you for joining me for this interview! To start, could you please tell our readers a bit about yourself and your research interests? I’m a space plasma physicist at Imperial College London, studying how the interaction between the solar wind and our magnetosphere leads to a huge amount of dynamics and waves that play a role in space weather. I’m also the Chair of EGU’s Outreach Co ...[Read More]

In April this year a new mission is being launched by the European Space Agency, called JUICE, which stands for the Jupiter Icy Moons Explorer. This mission aims to make detailed observations of the giant gas planet Jupiter and its three large ocean-bearing moons – Ganymede, Callisto and Europa – with a suite of remote sensing, geophysical and in situ instruments. But beyond the excitement of a ne ...[Read More]

Camping under the stars is an experience that allows people to connect with the cosmos in a unique and profound way. As they set up their tents and gaze up at the night sky, they are reminded of the vastness and beauty of the universe. They can see the stars, the planets and other celestial objects, and feel a sense of awe and wonder. They are reminded that they are just a small part of something ...[Read More]

The light’s interaction with matter enables scientists to observe greenhouse gases from space, but also creates the shifting blue tones throughout the mountains that hikers travel long distances to admire! The blue shades are created by an effect called Raleigh scattering, where very small atmospheric particles between the viewer (or camera) and the mountains cause the shorter wavelength lig ...[Read More]
