"First Long-Lasting Radio Bursts Found Above Sunspots"

NASA-funded scientists have discovered long-lasting radio signals above sunspots on the Sun, similar to auroras on Earth, using the Karl G. Jansky Very Large Array in New Mexico. These signals, lasting over a week, provide insight into solar and stellar magnetic activities, challenging existing notions of solar radio phenomena and opening new avenues for exploration. The discovery may help understand distant stars and improve monitoring of the Sun's active regions.
