Answer 2

Let's start at the innermost layer of the Sun... the core. This is the very center of the Sun, where temperatures and pressures are so high that fusion can happen. The Sun is combining hydrogen into helium atoms, and this reaction gives off the light and heat that we see here on Earth. The density of the core is 150 times the density of water, and the temperatures are thought to be 13,600,000 degrees Kelvin.

The next layer is called the radiative zone, and stars at about 0.2 solar radii and ends at 0.7 radii. This is a region where the solar material is hot and dense enough that thermal radiation can transfer energy from the interior of the Sun. Energy makes its way very slowly through this layer of the Sun.

The next layer is the convection zone. In this region, the solar plasma isn't dense enough to transmit energy through radiation. Instead, heat is moved through convection. Thermal columns carry heat to the surface of the Sun, cool back down and then fall back towards the center of the Sun.

The layer of the Sun that we can see from Earth is called the photosphere. Below the photosphere, the Sun becomes opaque to visible light, and astronomers have to use other methods to probe its interior. The temperature of the photosphere is about 6,000 Kelvin, and gives off the yellow-white light that we see.

Above the photosphere is the atmosphere of the Sun. Perhaps the most dramatic of these is the corona, which is visible during a total solar eclipse.

We have written extensively about the Sun here on Universe Today. Here's an article about how active the Sun can sometimes become. And another about the source of the solar wind.

Here's a link to NASA's image about the layers of the Sun, and more info about the interior of the Sun.

We have recorded an episode of Astronomy Cast just about the Sun called The Sun, Spots and All.

Answer 3

The suns visable surface is called photosphere. There is an area above this photosphere that is named the reversing layer that extends about 300 miles. This reversing layer is responsible for most of the absorption lines that show in the specturm of the sun. The two outermost layers of the sun are the chromosphere and the corona.

Answer 4

The sun's atmosphere has three layers: the photosphere, the chromosphere, and the corona. The lowest region, the photosphere, is what we see as the surface of the sun. The chromosphere surrounds the photosphere. The corona is the final layer, extending millions of miles out from the others and being seen from Earth best during a solar eclipse.

Answer 5

There are several. The best known is the corona, the glowing "atmosphere" of the Sun. But because the Sun itself is so incredibly bright, we can only see the corona when our direct view of the Sun is blocked.

We first learned about this by watching solar eclipses, but we now do the same thing using a coronagraph, which creates artificial eclipses here in the lab any time we want them.

Answer 6

The temperature minimum, the chromosphere, the transition region, the corona, and the heliosphere

Answer 7

On a star, the chromosphere is the next layer above the photosphere.

Answer 8

thin layer above the visible surface

Answer 9

chromosphere

Answer 10

The corona.
