Scientists have discovered radio bursts above a sunspot that resemble radio emissions from auroras on Earth. The pink-purple streaks in this illustration represent the radio emissions, with higher-frequency radio signals in pink, closer to the sunspot, and lower frequencies in purple. The thin lines represent magnetic field lines above the sunspot. The sunspot is the dark region on the Sun at the bottom.
Detected about 25,000 miles above a sunspot – a relatively cool, dark, and magnetically active region on the Sun – such radio bursts had previously been observed only on planets and other stars., Newark, who is the lead author of a paper reporting the discovery in the January 2024 issue of Nature Astronomy. The research was first published online in November 2023.
These sunspot radio bursts also have other characteristics – such as their spectra and their polarization – that are much more like radio emissions produced in the polar regions of Earth and other planets with auroras. “The discovery excites us as it challenges existing notions of solar radio phenomena and opens new avenues for exploring magnetic activities both in our Sun and in distant stellar systems,” Yu said.
