Unveiling the Mysterious Aurora-Like Emissions Above a Sunspot

Astronomers have detected aurora-like radio emissions about 24,855 miles above a sunspot on the Sun's surface. The emissions, which are different from Earth's auroras, were observed to persist for over a week and occur at frequencies ranging from hundreds of thousands of kHz to roughly 1 million kHz. The researchers believe that the emissions are not related to solar flares but are instead caused by electrons feeding into magnetic field loops associated with the sunspot. The findings could help improve our understanding of stellar magnetic processes and astrophysical phenomena in other stars.
