what layer sun do we see in this photograph course here

Which layer do you see when you look at the Sun?

Which layer do you see when you look at a typical image of the sun? What we see as the "surface" of the sun is the photosphere . While the "surface" of the sun looks substantial enough, it is actually a near vacuum, at about 1 6000 the density of our atmosphere at sea level.

What are the layers of the sun's surface?

This graphic shows a model of the layers of the Sun, with approximate mileage ranges for each layer: for the inner layers, the mileage is from the sun's core; for the outer layers, the mileage is from the sun's surface. The inner layers are the Core, Radiative Zone and Convection Zone.

What is the Sun’s photosphere?

The sun's photosphere is the innermost layer of the sun that we can observe directly. (Image credit: NASA/SDO) The lowest layer of the sun's atmosphere is the photosphere — the innermost layer that we can observe directly.

What is the deepest layer of the Sun?

Photosphere - The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that.

Which layer of the Sun is the center of the Sun?

This is the movement that creates sunspots and solar flares. This layer marks the border of what we usually refer to as the Sun. The core is plasma, but its movement is extremely similar to that of a gas. The radiative zone is the second inner layer of the Sun.

What are the outer layers of the Sun?

The outer layers are the Corona, the Transition Region, the Chromosphere, and the Photosphere, while the inner layers are the Core, the Radiative Zone, and the Convection Zone. There are four outer layers of the Sun, and the Corona is the outermost one. It starts at about 1300 miles above the photosphere, and its temperature is measured ...

What is the photosphere?

The Photosphere is the last, innermost layer of the outer layers of the Sun. We are able to observe this layer directly, and its temperatures vary between 11,000 and 6,700 degrees Fahrenheit. The majority of this layer is covered by granulation, which is caused by bubbling gases and sunspots from magnetic fields.

What is the radiative zone of the Sun?

The radiative zone is the second inner layer of the Sun. It sits outside of the core, and it holds its extremely high temperature. The zone itself has a temperature of around 7 million degrees Fahrenheit. This layer serves as a passage for all the energy that is released by the core.

How many layers of the Sun are there?

There are four outer layers of the Sun, and the Corona is the outermost one. It starts at about 1300 miles above the photosphere, and its temperature is measured to be around 900,000 degrees Fahrenheit. It is impossible to see the Corona with the naked eye, but there is an exception.

Which layer of the Sun is the last layer?

It is an interesting thing to notice how the temperature in these layers grows the further away we move from the center of the Sun. The Photosphere is the last, innermost layer of the outer layers of the Sun. We are able to observe this layer directly, ...

How long does it take for a photon to travel through the Sun?

Photons travel through the radiative zone, and they can’t travel through long ranges of space, so it takes almost 50 million years for a photon to travel through this layer of the Sun. Finally, we have the core, as the innermost layer of the Sun. The core is plasma, but its movement is extremely similar to that of a gas.

The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region. More detail on the outer layers follows:

Which layer of the Sun is covered by granulation?

Most of the photosphere is covered by granulation. Chromosphere - The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere).

What is the temperature of the transition region?

Transition Region - The transition region is a very narrow (60 miles / 100 km) layer between the chromosphere and the corona where the temperature rises abruptly from about 8000 to about 500,000 K (14,000 to 900,000 degrees F, 7700 to 500,000 degrees C).

What is the source of solar flares?

The photosphere is also the source of solar flares: tongues of fire that extend hundreds of thousands of miles above the sun's surface. Solar flares produce bursts of X-rays, ultraviolet radiation, electromagnetic radiation and radio waves. [ Space Weather: Sunspots, Solar Flares & Coronal Mass Ejections]

How does the photosphere work?

The photosphere is marked by bright, bubbling granules of plasma and darker, cooler sunspots, which emerge when the sun's magnetic field breaks through the surface. Sunspots appear to move across the sun's disk. Observing this motion led astronomers to realize that the sun rotates on its axis. Since the sun is a ball of gas with no solid form, different regions rotate at different rates. The sun's equatorial regions rotate in about 24 days, while the polar regions take more than 30 days to make a complete rotation.

What are the layers of the atmosphere of the Sun?

Atmosphere of the Sun: Photosphere, Chromosphere & Corona. 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 ...

What is the name of the NASA probe that will explore the Sun?

Explore the sun with NASA’s Parker Solar Probe.

What is the third layer of the Sun's atmosphere?

The third layer of the sun's atmosphere is the corona. It can only be seen during a total solar eclipse as well. It appears as white streamers or plumes of ionized gas that flow outward into space. Temperatures in the sun's corona can get as high as 3.5 million degrees Fahrenheit (2 million degrees Celsius).

What are the layers of the Sun?

Starting from the middle, the Sun's layers are the core, the radiative zone, the convective zone, the photosphere, the chromosphere, and the corona. The two layers that are particularly interesting are the core (where nuclear fusion happens) and the photosphere (the brightest layer).

What is the brightest layer of the Sun?

The photosphere is the brightest layer of the Sun. Even though it is not the outside layer, it is the layer that we can see from Earth. It is kind of like shining a light through a window. You don't see the window; you see the light! You can remember this layer by thinking of a photograph of the sun. In the 'photo'graph, you are seeing the 'photo'sphere!

What is the chromosphere?

The chromosphere is a very thin layer just past the photosphere. We can see the chromosphere during certain eclipses (where the Sun, the Earth, and the Moon are all lined up). It has a red color when we can see it. The chromosphere is basically gases from the Sun burning off into space from the large amount of heat that is there.

What is the process of the Sun's core?

Just like the Earth, the Sun has a core. Unlike the Earth's core, though, the Sun's core is where the fuel of the Sun (hydrogen) is being used for energy. This process is called nuclear fusion. All the heat and light that we feel here on Earth started in the Sun's core through the process of nuclear fusion.

What is the Sun?

The Sun is the star at the center of our Solar System. Just like the Earth and the other planets, the Sun has several layers. In this lesson, we will talk about the Sun and its layers.

Is the Sun a ball of fire?

Have you ever heard someone say the Sun is a big ball of fire? That isn't true! In fact, the Sun isn't fire at all. The Sun is made up of layers, and none of the layers are made of fire. Take a look at the image to see all the layers together, and then we'll talk about what each one is, starting with the center of the sun and ending with the outside, closest layer to Earth.

What layer of the Sun gives the Sun its color?

Photosphere Gives the Sun Color. The photosphere is the layer that can be seen from the Earth. The temperature of the photosphere is about 10 million degrees Fahrenheit. The surface of this area can be seen through a telescope.

Which layer of the Sun is not dense enough to transmit energy?

The convection zone is not dense enough to transmit energy. Instead, this layer moves heat to the surface of the sun where it cools and drops back into the convection zone where it reheats.

How much heat does the Sun get from the core?

The heat from the core is 15 million degrees Kelvin which translates to roughly 27 million degrees Fahrenheit. Kelvin is a temperature scale that picks up where the Celsius degree ends. The core is comprised of a radiative layer that emits radiation and a convective layer that transfers heat. The heat inside the core causes protons and electrons to rub together creating an energy source for the Sun.

What is the radiation zone?

The Radiation Zone. The radiation zone is just outside the core. The function of this layer is to transfer energy from the core to the other layers. The temperature at this layer is cooler than the core at 7 million degrees Fahrenheit causing thermal radiation. This layer has 60 percent mass and 90 percent volume.

What is the chromosphere?

Chromosphere can be seen during an Eclipse. Above the photosphere is the sun’s solar atmosphere that includes the chromosphere. It is the same diameter as the Earth and is about 35 million degrees Fahrenheit. Sometimes the chromosphere can be seen during an eclipse.

What is the sun made of?

The sun is made of several complex layers, each with its own unique job that ultimately produces energy. This energy controls the Earth’s climate and weather and provides life for all living things on earth.

Is the Sun a gas?

The sun has many chemical elements but since it is so hot they are in a gaseous state. The color of the sun is actually white, but from Earth, it appears yellow. The sun is so dense that there is no surface.

What is the visible surface of the Sun?

The photosphere is the visible surface of the Sun that we are most familiar with. Since the Sun is a ball of gas, this is not a solid surface but is actually a layer about 100 km thick (very, very, thin compared to the 700,000 km radius of the Sun).

What are the features of the photosphere?

These features include the dark sunspots , the bright faculae, and granules . We can also measure the flow of material in the photosphere using the Doppler effect. These measurements reveal additional features such as supergranules as well as large scale flows and a pattern of waves and oscillations.

How is the Sun's rotation detected?

This rotation was first detected by observing the motion of sunspots in the photosphere. The Sun's rotation axis is tilted by about 7.15 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March. Since the Sun is a ball of gas it does not have ...

How long does it take for the Sun to rotate?

In fact, the Sun's equatorial regions rotate faster (taking about 24 days) than the polar regions (which rotate once in more than 30 days).

What are the pillars of stars?

The pillars are clouds of gas and dust in which many new stars are forming; the edges of the pillars are sculpted by ultraviolet radiation from stars outside the pillars.

What are spikes in photography?

The spikes are an artifact of photography through a telescope.
