Eclipse research: Following in the moon's slipstream to capture high-res sunspot images

While much of the research around the eclipse on Monday will focus on the effects of the Sun’s brief, daytime disappearance on Earth and its atmosphere, a group of solar physicists will be leveraging the rare event to capture a better glimpse of the star itself.

Studying the Sun's atmosphere with the total solar eclipse of 2017

A total solar eclipse happens somewhere on Earth about once every 18 months. But because Earth’s surface is mostly ocean, most eclipses are visible over land for only a short time, if at all. The total solar eclipse of Aug. 21, 2017, is different — its path stretches over land for nearly 90 minutes, giving scientists an unprecedented opportunity to make scientific measurements from the ground.

Chaotic magnetic field lines may answer the coronal heating problem

It is known that the sun’s corona is roughly 100 times hotter than its photosphere — the sun’s visible layer. The reason for this mysterious heating of the solar coronal plasma, however, is not yet entirely understood. A research team in India has developed a set of numerical computations to shed light on this phenomenon, and present this week in Physics of Plasmas, analysis examining the role of chaotic magnetic fields in potential heating mechanisms.
