The atmosphere of the sun is composed of several layers, mainly the photosphere, the chromosphere and the corona. It's in these outer layers that the sun's energy, which has bubbled up from the sun's interior layers, is detected as sunlight.The lowest layer of the sun's atmosphere is the photosphere. It is about 300 miles (500 kilometers) thick. This layer is where the sun's energy is released as light.Because of the distance from the sun to Earth, light reaches our planet in about eight minutes.t's in these outer layers that the sun's energy, which has bubbled up from the sun's interior layers, is detected as sunlight. The lowest layer of the sun's atmosphere is the photosphere. It is about 300 miles (500 kilometers) thick. The chromosphere is a thin layer above the photosphere. Above that, the corona, or solar atmosphere, extends far into space. We do not usually see these parts of the Sun because they are not as bright as the photosphere, but during a total eclipse they are visible because the Moon blocks the light from the photosphere.he chromosphere is a thin layer above the photosphere. Above that, the corona, or solar atmosphere, extends far into space. We do not usually see these parts of the Sun because they are not as bright as the photosphere, but during a total eclipse they are visible because the Moon blocks the light from the photosphere. The sun has many different layers that make up the sun: Core Radiation Zone Convection Zone Photosphere-sunspots Chromosphere Transition Region Corona The Core is the layer … that stores all of the sun's energy. The Radiation Zone transfers the energy that the Core passes.The Convection Zone carries the sun's energy to the surface. The Photosphere is the visible surface of the sun. The Chromosphere is a thin surface above the Photosphere.The Corona is the sun's atmospheric layer.+ 13 others found this useful.he Radiation Zone transfers the energy that the Core passes. The Convection Zone carries the sun's energy to the surface. The Photosphere is the visible surface of the sun. The Chromosphere is a thin surface above the Photosphere. The Photosphere. 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.he Core of the Sun. Let’s start at the innermost layer of the Sun, the core of the Sun. 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 PHOTOSPHERE, the Sun’s visible surface, is the next layer of the Sun. The bubbling motion of the convection layer makes the granular patterns we see on the photosphere.The granules may look small in pictures, but scientists estimate they are really about the size of the Moon.hat’s HOT! The Sun’s next layer is the CONVECTION ZONE. Convection is how energy moves from the inner parts of the Sun to the outer pa rt of the Sun that we see. We can see convection when we look at a pot of boiling water. In a white light photo, the part of the Sun that we see is called the photosphere. It has a temperature of about 6000 degrees Celsius, much cooler than the corona. Sometimes there are notable dark spots.These sunspots come and go, so look at the Sun again in a few days to see how its appearance has changed.n a white light photo, the part of the Sun that we see is called the photosphere.

The sun has many different layers that describe its structure. Core. Radiation zone. Convection zone. Photosphere-sunspots. Chromosphere. Transition region. Corona. Core. The core is the innermost layer of the sun and it is a source for all the Sun's energy.he sun has many different layers that describe its structure. Core. Radiation zone. Convection zone.

It starts at an optical depth of 2/3, I think. Our sun has a sharp-edged photosphere because it has a convective envelope, so the 2/3 of an optical depth is a small distance compared to the sun's radius.he photosphere.
