New observations made with instruments aboard Japan's Hinode satellite reveal the hotter outer atmosphere is due to nanoflares.
Nanoflares are small, sudden bursts of heat and energy. "They occur within tiny strands that are bundled together to form a magnetic tube called a coronal loop,"

What else can I help you with?
What is the suns Outermost layer?
The Sun's outermost layer is the corona, which is the Sun's tenuous outer atmosphere that is visible during a solar eclipse as a white halo around the Sun. The corona extends millions of kilometers into space and is much hotter than the Sun's surface.
What is the outer most layer of the suns atmosphere?
The outermost layer of the sun's atmosphere is called the corona. It is only visible during a total solar eclipse or with specialized instruments like a coronagraph. The corona is much hotter than the layers below it, despite being farther from the sun's surface.
Which is hotter the sun or the earths crust?
The sun is much hotter than the Earth's crust. The temperature at the Earth's core is estimated to be around 5700 degrees Celsius, whereas the temperature at the surface of the sun is about 5500 degrees Celsius.
Which of the suns layers is only visible during eclipses?
The corona is the sun's outermost layer, which is only visible during a total solar eclipse when the moon covers the sun's surface. The corona is much dimmer than the sun's surface, making it visible only when the sun's bright photosphere is blocked.
Why is it usually impossible to see the suns corona?
The corona can be seen only during solar eclipses, when the main radiation from the Sun's surface is blocked by the passage of the Moon or with special instruments. The corona isn't as bright as the other parts of the sun and the solar eclips blocks that brightness.
What is suns hotter region directly above the visible surface?
The hottest region directly above the visible surface of the Sun is the corona, which is an outer layer of the Sun's atmosphere. Temperatures in the solar corona can reach millions of degrees Kelvin, much higher than the visible surface temperature of about 5,500 degrees Celsius.
If a scientist is studying the suns corona what will he find?
One interesting thing that has been found about the corona is that it's much hotter than the Sun's surface - while the Sun's surface has a temperature of about 6000 K, the corona has a temperature has a temperature around a million K. This obviously can't be caused by regular heat transfer; scientists are still researching exactly how the energy gets from the Sun to the corona.

The Sun's outermost layer is the corona, which is the Sun's tenuous outer atmosphere that is visible during a solar eclipse as a white halo around the Sun. The corona extends millions of kilometers into space and is much hotter than the Sun's surface.
Which is hotter the surface of the earth or sun?
The suns surface is hotter, estimated to be around 5500-6000 Kelvin.
Why is suns core hotter?
The corona is hotter than the photosphere because the sun's magnetic field carries energy upward from the surface and into the chromosphere and corona. The opposite effect is observed when the magnetic fields cause sunspots to form resulting in cooler surfaces.
How is heat distributed in the surface zone of the zone?
By the SUNS ENERGY. (Which makes it hotter and hotter.)

Is the Inner Core hotter Than The Suns Inner Core?
No it is not, however it is similar to that of the sun's surface
What is the outer layer of of the suns atmosphere?
The Corona I believe. You should check a diagram of the sun as well.The parts of the sun's atmosphere from the surface outward are the photosphere, the chromosphere, the corona, and the outer layers of the corona called the solar wind. The photosphere is the visible part of the Sun's atmosphere.The parts of the sun's atmosphere from the surface outward are the photosphere, the chromosphere, the corona, and the outer layers of the corona called the solar wind.
