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.
