Solar scientists have observed a stunning display of radio waves over a sunspot, and these emissions strikingly resemble auroral displays on Earth known as the Northern Lights.
Happening around 25,000 miles (40,000 kilometers) over a dark, relatively cool patch of the sun, these "auroral" radio emissions could not only shine a light on the dynamics of intense solar radio bursts, but also on large starspots beyond our solar system. The signals were spotted by astronomers from New Jersey Institute of Technology’s Center for Solar-Terrestrial Research (NJIT-CSTR).
