Small solar flares helping shed light on the Sun s mysterious heating process

“Campfires”, or mini solar flares that occur on the surface of the Sun, are helping shed light on a mysterious solar heating phenomenon that has baffled experts for decades. New data from the European Space Agency’s (ESA) Solar Orbiter suggests these so-called campfires are driven by a process that may also contribute to heating of the Sun’s outer atmosphere, or corona. The Sun’s corona is much hotter, around 300 times, than the layers below – a strange feature that has puzzled scientists and is thought to be one of the biggest mysteries in solar physics. Solar flares are brief eruptions of high-energy radiation from the Sun’s surface, which can cause radio and magnetic disturbances on the Earth.

Sun s unimaginably hot outer atmosphere can reach staggering temperatures of 1 7MILLION°F

The unimaginably hot outer layer of the sun s atmosphere can reach temperatures of 1.7 million degrees Fahrenheit due to campfires on the surface, study finds. In June last year, ESA released the closest images ever taken of the sun, by the Solar Orbiter, which, for the first time, showed campfires dotted across its surface. The images revealed around 1,500 small, flickering brightenings that last for between 10 and 200 seconds and span between 248 and 6,500 miles across. New data from the European Space Agency s (ESA) Solar Orbiter suggests these campfires are driven by a process that may also contribute to heating of the sun s outer atmosphere, or corona, triggering temperatures of 1.7 million Fahrenheit.
