Story summary

Astrophysicists detected repeating bursts of radio waves from YZ Ceti b, a rocky exoplanet 12 light-years away.
The bursts indicate that YZ Ceti b has a magnetic field.
The bursts align with the planet's two-day orbit, implying star-planet interactions.
Researchers say the signals could reveal extrasolar space weather and insights into habitability, though YZ Ceti b is likely too hot for life.
The findings were published in Nature.
