When astronomers detected potential biosignatures in the atmosphere of exoplanet K2-18 b, it raised a critical question, could this world's atmosphere even survive its host star's radiation? A new study using the Very Large Array searched for radio emissions from the K2-18 system and found something surprising, it was absolutely silent. That absence of radio signals reveals K2-18 is an unusually quiet star, suggesting the planet's atmosphere faces minimal erosion from stellar activit...
