Possible Discovery of Life-Sustaining Magnetic Field on Rocky Exoplanet
TL;DR Summary
Astronomers have traced a repeating radio signal back to a rocky, Earth-sized exoplanet known as YZ Ceti b, which appears to have a magnetic field, a crucial factor that makes a world habitable. The planet is orbiting a small red dwarf star located around 12 light-years from Earth. A magnetic field is what stops a planet's atmosphere from being stripped away by powerful stellar winds. The repeating radio signal may be the clue we need to detect more life-friendly worlds like it in the future.
