[HIGHLIGHTS] Unexpected signal from an alien planet - "Clear indication that we may have something here"

A radio signal from an Earth-sized exoplanet makes a research team prick up their ears. Apparently, the planet has a magnetic field.

YZ Ceti b is a rocky planet orbiting a star about twelve light-years from Earth. Researchers suspect that the radio waves they have discovered are interactions between the magnetic field of the planet and the star. Such radio waves must be very strong due to the great distance of twelve light years. So far, only Jupiter-sizedExoplanets with magnetic fields have been discovered.
