Researchers captured the most detailed images of the sun's corona, revealing pink 'raindrops' of cooling plasma, using advanced adaptive optics technology at the Big Bear Solar Observatory, providing new insights into solar phenomena.
Researchers at the Big Bear Solar Observatory have discovered intense wave energy from the sunspot umbra that could maintain million-degree temperatures in the Sun’s corona. The finding is the latest key to unraveling a host of related mysteries pertaining to Earth’s nearest star. The coronal heating problem is one of the biggest mysteries in solar physics research, and with this study, researchers have fresh answers to this problem, which may be key to untangling many confusing questions in energy transportation and dissipation in the solar atmosphere, as well as the nature of space weather.
