May 03, 2023[Interview] Solar Sails Are Even Better Than You Think
Can solar sails change the way we explore the Solar System and beyond? Dr Slava Turyshev definitely thinks so! He assembled an all-star team of researchers in a recent paper about potential science opportunities of using solar sails. In this interview, we talk about the technology behind it, what's its current state, what perspectives it has and much more.

April 19, 2023[Interview] Detecting Earth-Size Exoplanets with Magnetospheres
Magnetospheres seem to be a very important factor when considering how habitable a planet is. So it was really exciting when it was announced that an Earth-size exoplanet's magnetosphere was detected using radio telescopes. It can also be a method to look for exoplanets by detecting their magnetic fields.
I'm discussing this discovery with Dr Joe Pesce who is the Program Director at National Science Foundation.
More about the discovery:
