Summary:
- Astronomers have created the first detailed map of the Sun's coronal magnetic field, which is the magnetic field in the Sun's outer atmosphere or corona.
- This map provides a better understanding of the Sun's activity and how it affects the Earth, including space weather events like solar flares and coronal mass ejections.
- The new mapping technique uses observations from the Daniel K. Inouye Solar Telescope (DKIST) in Hawaii, which is the world's largest and most powerful solar telescope, to measure the magnetic field in the Sun's corona.
