Tiny "nanoflares" might heat the Sun's corona
Why is the Sun's million-degree corona, or outermost atmosphere, so much hotter than the Sun's surface? This question has baffled astronomers for decades. Today, a team led by Paola Testa of the Harvard-Smithsonian Center ...

Solar dynamic loops reveal a simultaneous explosion and implosion, plus evidence for magnetic reconnection
(Phys.org) —Movies of giant loops projecting from the surface of the Sun are giving new insights into the complex mechanisms that drive solar flares and Coronal Mass Ejections (CMEs). These eruptions release vast energy ...

Tiny Flares Responsible for Outsized Heat of Sun's Atmosphere
(PhysOrg.com) -- Solar physicists at NASA have confirmed that small, sudden bursts of heat and energy, called nanoflares, cause temperatures in the thin, translucent gas of the sun's atmosphere to reach millions of degrees.

Small-scale magnetism leads to large-scale solar atmosphere
Thanks to close-up images of the sun obtained during Solar Orbiter's perihelion passage of October 2022, solar physicists have seen how fleeting magnetic fields at the solar surface build up into the solar atmosphere.

The coronal veil: Are the sun's magnetic arches an optical illusion?
From afar, the Sun appears blank and featureless in visible light. But through a solar telescope in different wavelength, it is revealed to be much, much more.
