Scientists have picked out yet another radio signal that could be a sign that aliens live on a distant planet.
A “coherent” radio signal has been detected coming from an exoplanet named YZ Ceti b, which is located about 12 light years from Earth -- which is over 70 trillion miles away. The National Science Foundation's National Radio Astronomy Observatory believes that picking up a signal this strong from such a long distance away means the exoplanet's magnetic field is similar to the one here on Earth. That makes it a strong candidate to be able to sustain life.
