The Sun’s Corona is what makes the sky look yellow.
The Sun’s corona is what makes the sky look yellow during a total solar eclipse. The corona is a tenuous plasma and magnetic field surrounding the Sun. When light from the Sun passes through this, it appears as a bright white ring around the black disc of the Moon. However, when light from the Sun passes through it at an angle, it appears as a golden or yellow glow around the Moon. This phenomenon was seen in totality across much of North America on August 21st and was one of many sights to see during this year’s total solar eclipse.
