Aurora-Like Radio Emission Discovered Above Sunspot

The novel emission, detected by scientists from the New Jersey Institute of Technology, shares characteristics with auroral emissions seen around Earth and other planets, offering new insights into stellar magnetic processes.

Scientists from the New Jersey Institute of Technology's Center for Solar-Terrestrial Research have discovered a novel aurora-like radio emission occurring 40,000 km above a sunspot on the Sun.
The radio emission shares characteristics with the auroral radio emissions commonly seen in planetary magnetospheres such as those around Earth, Jupiter and Saturn, as well as certain low-mass stars.
The newly observed solar radio emissions, detected over a vast sunspot region where magnetic fields on the Sun's surface are particularly strong, differ from previously known solar radio noise storms.
The sunspot aurora emissions occur at frequencies ranging from hundreds of thousands of kHz to roughly 1 million kHz, a direct result of the sunspot's magnetic field being thousands of times stronger than Earth's.
The discovery could have implications for astrophysicists to rethink their current models of stellar magnetic activity and may reveal fundamental connections in astrophysical phenomena.
