The solar corona as a research area focuses on the physical processes governing the Sun’s outer atmosphere, characterized by low densities, high temperatures (∼10⁶ K), and complex magnetic structures. It integrates observational solar physics, plasma astrophysics, and magnetohydrodynamics to study coronal heating, magnetic reconnection, wave propagation, flares, and coronal mass ejections. Research emphasizes multi-wavelength diagnostics (EUV, X-ray, radio), spectropolarimetry, and numerical modeling to infer coronal magnetic fields, energy transport, and particle acceleration. This domain is central to understanding space weather, heliospheric conditions, and the coupling between the photosphere, chromosphere, and interplanetary medium.
On its record-breaking pass by the sun late last year, NASA's Parker Solar Probe captured stunning new images from within the sun's atmosphere. These newly released images—taken closer to the sun than we've ever been before—are ...
