"NASA-Supported Team Detects Aurora-Like Radio Bursts Above Sunspot"

A NASA-supported team has discovered long-lasting radio signals resembling auroras above a sunspot on the Sun, a phenomenon previously observed only on planets and stars. These radio bursts, detected using the Karl G. Jansky Very Large Array, could provide insights into solar behavior and similar emissions from distant stars. The discovery challenges existing notions of solar radio phenomena and suggests that aurora-like radio emissions may also originate from large spots on stars. NASA's heliophysics fleet is poised to further investigate the source regions of these radio bursts, while the team plans to reexamine other solar radio bursts for similar emissions.
