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]

A touch of space weather! An EGU funded outreach project for blind and visually impaired students

Lenka Zychova January 4, 2023

This image shows four tactile images created to share space weather phenomena with blind and visually impaired learners. The image shows a representation of the magnetosphere (a small blue ball with black concentric circles surrounded by dots to the left and right, the ones on the left are smaller), aurora formation (a small blue ball with black concentric circles to the left and right with dots on the circles) and radiation belts ( a small blue ball with a yellow and brown pair of rings extended evenly to the left and the right). All the images are on a white background.

We can all probably agree that the Northern Lights are one of the world’s most spectacular natural displays. But how do we share this beauty with children who are blind? How do we explain the processes behind the aurora creation to the visually impaired when all the illustrations of Earth’s magnetosphere are in 2D? The Northern Lights are just one of the consequences of ‘space weather’. Space weat ...[Read More]

Across the EGU’s official blog, GeoLog and division blogs we had so many inspiring, thought-provoking and even entertaining posts this year. Thank you t ...[Read More]

Around 17th July 2020, the core of the Neowise comet starting giving off a greenish-glow. At first I thought this strange colour was due to some glitch in my camera sensor (I used an entry-level DSLR), but other photos online also started reporting this greenish glow. It has since been speculated to be because of the formation of a new vent on the surface of the comet, discharging gaseous ions whi ...[Read More]
