Page 4: Research news on Solar corona

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.

PUNCH mission instruments collect first images

The Southwest Research Institute-led Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission collected its first images following its March 11 launch into polar orbit around Earth. The mission's four small suitcase-sized ...

Mars's rare disappearing solar wind event explained

Mars's atmosphere and climate are impacted by interactions with solar wind, a stream of plasma comprised of protons and electrons that flows from the sun's outermost atmosphere (corona), traveling at speeds of 400–1,000 kilometers ...

Five space mysteries Proba-3 will help solve

ESA's Proba-3 will be the first mission to create an artificial total solar eclipse by flying a pair of satellites 150 meters apart. For six hours at a time, it will be able to see the sun's faint atmosphere, the corona, ...

Video: Proba-3's journey to see the sun's corona

The double-satellite Proba-3 is the most ambitious member yet of ESA's Proba family of experimental missions. Two spacecraft will fly together as one, maintaining precise formation down to a single millimeter.
