Possible Discovery of Alien Life Through Repeating Radio Signal from Earth-Sized Exoplanet

Astronomers have detected repeating radio signals from a rocky planet orbiting a star only 12 light years from Earth, which they believe could be an Earth-sized world with a magnetic field, making it a strong candidate for harboring an atmosphere. The detection of a magnetic field on the exoplanet, dubbed YZ Ceti b, is a big deal because scientists have long struggled to detect magnetic fields on smaller, terrestrial worlds like our own planet, which has remained one of the biggest obstacles in the search for potentially habitable, life-sustaining worlds.
