What layer of the Sun is just below the photosphere?

The area of the Sun’s interior immediately below the photosphere is called the convection (or convective) zone. The lower section of the Sun’s atmosphere, the chromosphere, lies above the photosphere.

How did we figure out the layers of the Sun?

The interior of the Sun is too dense to be seen (photons of light are unable to stream out into space and to the Earth) so scientists use a method known as helioseismology to probe the structure in this part of the Sun. … Many telescopes on the Earth study the Sun in white light.

Why can’t you see deeper than the photosphere?

Why can’t you see deeper into the Sun’s photosphere? Light moving through the sun’s outer layers keep changing the direction that the photons move through, so you don’t get information about what was at lower depths inside the sun. You just see the hot outermost layer: the photosphere.

Why can’t we see the material below the Sun’s photosphere?

Since the Sun is made up of hot gas, there isn’t really a “surface” to it. Instead, as you move from space toward the Sun’s core, the gas gets denser and denser. The photosphere represents the depth at which we can see no deeper toward the core of the Sun.

How can astronomers detect structure in the chromosphere?

How can astronomers detect structure in the chromosphere? Ans: The structure of the chromosphere is studied primarily using filtergrams. Filtergrams are images of the sun taken through a filter that lets in a very narrow wavelength band of light, such as light emitted by the Hydrogen-alpha transition.

How can astronomers detect neutrinos from the Sun?

Physicists have directly detected pp neutrinos, demonstrating that about 99 per cent of the power of the Sun is generated by the pp fusion process. … Now, physicists using the Borexino detector – one of the most sensitive neutrino detectors on Earth – have succeeded in detecting pp neutrinos.

How do astronomers learn about the interior of the sun?

What efforts are being made to explore the sun?

NASA’s Parker Solar Probe is a $1.5 billion mission to explore the sun like never before. Launching in August 2018, the mission will send a hardy spacecraft to “touch” the sun by flying through the star’s super-hot outer atmosphere: the corona.

How do astronomers know how strong the magnetic field of the sun is?

Astronomers can measure magnetic fields on the sun using . Sunspots have extremely strong magnetic fields which are believed to inhibit the flow of gas. Consequently, convection is reduced below the sunspot and the surface there is cooler.

What type of energy transport is occurring just below the photosphere?

What type of energy transport is occurring just below the photosphere? What is the evidence in the photosphere of the type of energy transport occurring beneath it? A certain type of energy transport (radiation, convection, or conduction) occurs just below the photosphere.

Why do scientists study the sun so closely instead of other stars?

The sun is a normal star. It is much closer to us than any other star, and by studying the sun, we can therefore learn more about other stars. The better we understand other stars, the more we know about the Milky Way. … If it weren’t for the sun, our planet would simply fly off loose into the universe.

What is the best reason astronomers have come up with to explain why sunspots are cooler and look darker?

Magnetic fields also hold the key to explaining why sunspots are cooler and darker than the regions without strong magnetic fields. The forces produced by the magnetic field resist the motions of the bubbling columns of rising hot gases.

What mechanisms do astronomers believe are responsible for making the Sun’s outer atmosphere so much hotter than its photosphere?

What mechanisms do astronomers believe is responsible for making the Sun’s outer atmosphere so much hotter than its photosphere? The Sun’s magnetic field interacting with the charged particles that make up the atmosphere. Why do sunspots appear dark?

Why is the photosphere cooler than the chromosphere?

While the center of the Sun’s core can get as hot as 30 million degrees F, its outer layers cool down. The photosphere, which is outside the core, is the coolest layer. … In the chromosphere, the rising heat causes hydrogen to give off the reddish light seen in the prominences during solar eclipses.

What does the chromosphere of the Sun do?

The layer above the photosphere is the chromosphere. The chromosphere emits a reddish glow as super-heated hydrogen burns off. But the red rim can only be seen during a total solar eclipse. … The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona.

When the chromosphere can be seen during a solar eclipse it appears quizlet?

the interior structure of the Sun. What two energy transport mechanisms, in order from outside the core to the surface, is found in the Sun? When the chromosphere can be seen during a solar eclipse, it appears: red.

Can we see the chromosphere of the Sun?

Because it is such a thin layer and made of such tenuous plasma, the chromosphere is normally hidden from our view… it’s light is drowned out by the brilliance of the underlying photosphere. It is typically only seen during a solar eclipse or through the use of special telescopes on satellites.

What evidence do we have that the chromosphere is hotter than the photosphere quizlet?

What evidence do we have that the chromosphere is hotter than the photosphere? Astronomers know that the chromosphere is hotter than the photosphere through observing the amount of ionization. They observe that the chromosphere is hot enough to produce x-rays that can be studied with telescopes.

Why are astronomers so interested in detecting neutrinos from the sun?

What is a neutrino, and why are astronomers so interested in detecting neutrinos from the sun? Neutrinos are “ghost” particles that are released in the thermonuclear reactions in the Sun. They are “ghost” particles in that they are extremely difficult (but not impossible) to detect.

How can astronomers detect neutrinos from the Sun quizlet?

How can astronomers detect neutrinos from the Sun? They observe nuclear reactions triggered by neutrino collisions in large underground pools of chemicals.

Why do astronomers study neutrinos from the sun?

When astronomical bodies, such as the Sun, are studied using light, only the surface of the object can be directly observed. … Since neutrinos are also created in the cores of stars (as a result of stellar fusion), the core can be observed using neutrino astronomy.

How do astronomers get information about the interior structures of the sun quizlet?

Astronomers can glean an enormous amount of information about the Sun from an analysis of the absorption lines that arise in the photosphere and lower atmosphere. … Above the photosphere lies the cooler chromosphere, the inner part of the solar atmosphere.

What do astronomers use to study the sun?

There are two ways that solar telescopes can gather information from the light emitted by the sun. There are spectrometers that can simultaneously observe different wavelengths of light, generating graphs that give a composite picture of the temperature ranges in the material around the sun.

How do astronomers study the conditions and properties of the sun’s interior?

However, astronomers have indeed devised two types of measurements that can be used to obtain information about the inner parts of the Sun. One technique involves the analysis of tiny changes in the motion of small regions at the Sun’s surface. The other relies on the measurement of the neutrinos emitted by the Sun.

Solar Interior

The indoors of the Sun is just too dense to be visible (photons of mild are not able to circulate out into the area and to the Earth) so scientists use a technique called helioseismology to probe the shape of this part of the Sun. Helioseismologists pay attention to the track of the Sun with the aid of using reading sound waves that soar round internally. The mirrored image of the sound waves off the internal of the photosphere reasons the floor to pulsate very slightly, and the growing and falling of the photosphere may be measured to present facts at the density and motions of the fabric in the Sun.

Photosphere

The photosphere changed into the primary part of the Sun to be studied as it may be visible in white mild, the identical mild that we hit upon with our eyes. Many telescopes at the Earth take a look at the Sun in white mild. In a few instances, the telescopes use filters to lessen the quantity of mild received from the Sun. The Sun ought to by no means be regarded with the aid of using the human eye without decreasing the quantity of mild to a millionth of the preliminary brightness!

Chromosphere

The temperature of the chromosphere is better than the photosphere and may be determined with the aid of using mild emitted from ionised Helium. This mild is withinside the Ultra-violet a part of the electromagnetic spectrum and unique telescopes are used that are touchy to those wavelengths.

Flares launch big quantities of strength and warmth the coronal plasma to many tens of tens of thousands and thousands of stages. The strength launched is visible thru out the spectrum together with X-rays, gamma-rays, UV, and radio waves, so unique devices are required which can be touchy at those wavelengths. The YOHKOH satellite tv for pc carried many devices together with the Soft X-ray Telescope (SXT). This device is able to take pictures of the sun corona withinside the temperature variety 2-four million stages, Kelvin.

How do we study coronal mass ejections?

Coronal mass ejections (CME) are detected in white mild whilst the disc of the Sun is occulted with the aid of using a device referred to as a coronagraph. Most of the Sun’s mild is emitted from the photosphere and this desires to be blocked if the fainter corona is to be visible. The density improvements of the CME are visible with the aid of using the scattering of the photospheric mild off the electrons withinside the corona with the aid of using a manner referred to as Thomson scattering.

What effect does solar activity have on earth?

The Sun’s irradiance has its best impact on Earth’s higher ecosystem, even as the decreased ecosystem insulates Earth from the multiplied heat. If the Sun has been riding Earth’s warming, one might assume to look that higher ecosystem getting an increasing number of hot.
