Discovery of Magnetic Fields on Exoplanets Brings Hope for Alien Life

An Earth-sized exoplanet, YZ Ceti b, located 12 light-years away from Earth, has been found to have aurora, which may indicate the presence of an Earth-like magnetic field and atmosphere. The discovery was made using the Karl G. Jansky Very Large Array of telescopes in New Mexico, which detected strong radio waves believed to be created by the star YZ Ceti interacting with the planet's magnetic field. This is the first time a magnetic field has been found around an Earth-sized exoplanet, making it a promising candidate for a rocky exoplanet with a magnetic field. Follow-up work is needed to confirm the findings.
