Researchers at the New Jersey Institute of Technology’s Center for Solar-Terrestrial Research (NJIT-CSTR) have captured images of the recent solar eclipse that show the famous “ring of fire” effect in a way never seen before. The eclipse was only visible for a short time for those within its path, but the new observations using radio waves have yielded stunning images of the eclipse’s ring lasting for over an hour. The researchers used the Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) in California to make their breakthrough observation. This allowed them to see the extended corona of the Sun as the moon passed between Earth and the Sun. The radio images provide a much larger view of the solar disk than can be seen with the naked eye. The OVRO-LWA project, funded by the National Science Foundation, aims to study the Sun’s extended corona with the highest resolution possible at radio wavelengths. The team is now developing an automated data processing pipeline to produce near-real-time solar images, which will open new opportunities for discovery in solar astronomy and space weather studies.
