Groundbreaking Achievement: NSF Daniel K. Inouye Solar Telescope Produces its First Magnetic Field Maps of the Sun’s Corona

The U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope, the world’s most powerful solar telescope, operated by the NSF National Solar Observatory (NSO), achieved a major breakthrough in solar physics by successfully producing its first detailed maps of the Sun’s coronal magnetic fields. This milestone, led by NSO Associate Astronomer Dr. Tom Schad, was recently published in Science Advances, and promises to enhance our understanding of the Sun’s atmosphere and how its changing conditions lead to impacts on Earth’s technology-dependent society. The corona, or the Sun’s outer atmosphere, greatly influences solar winds and space weather events like solar flares and coronal mass ejections. However, the magnetic forces that drive these events and the corona are challenging to measure.
