Discovering the Sun's Mysteriously Hot Atmosphere

The video explores the unexpected temperature behavior of the sun, particularly the corona, which is much hotter than the surface. This phenomenon, known as the coronal heating problem, was first observed during an eclipse in the 1800s. Scientists used spectroscopes to study the light from the corona, discovering a unique green line indicating high temperatures. Theories suggest that waves or magnetic field realignments may contribute to the corona's heat. Understanding this requires direct observations from the corona itself.

What is the temperature of the sun's core in degrees Fahrenheit?
