How Are Astronomers Able To Explore The Layers Of The Sun Below The Photosphere??
How are astronomers able to explore the layers of the sun below the photosphere? … By observing solar X rays and gamma rays with space telescopes. These shorter wavelengths are emitted from hotter regions below the photosphere.
How do scientists determine 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.
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 do astronomers know what the outer layers of the Sun are made of?
How do astronomers know the composition of the outer layers of the Sun? We take an absorption line spectrum of the Sun. These absorption lines tell us what elements are present in the outer layers. Solar wind particles can be captured by the Earth’s magnetosphere.
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.
How do astronomers collect data about 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 learn about the interior of the sun?
They can study its radiation using radar or its interior using techniques such as acoustic interferometry. U.S. National Solar Observatory: The observatory has two major optical facilities called the Dunn Solar Telescope (Sacramento Peak) and the McMath-Pierce Solar Telescope (Kitt Peak).
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.
What happens in the chromosphere of the Sun?
NASA/Marshall Solar Physics. The chromosphere is an irregular layer above the photosphere where the temperature rises from 6000°C to about 20 000°C. At these higher temperatures hydrogen emits light that gives off a reddish color (H-alpha emission).
What type of energy transport is occurring just below the photosphere quizlet?
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.
What mechanisms do astronomers believe is responsible for making the Sun’s outer atmosphere?
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.
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 is the best reason astronomers have come up with to explain why sunspots?
What is the best reason astronomers have come up with to explain why sunspots are cooler and look darker? Sunspots are places where the strong magnetic fields in the Sun resist the upward motion of bubbling hot gases from underneath. … Coronal Mass Ejections from the Sun have many serious effects on or near the Earth.
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.
Why does nuclear fusion in the Sun occur only near the center?
Tremendous temperatures and pressures are required to force the protons close enough together for the fusion process to take place so these reactions can only occur in the core of the Sun where the temperature reaches up to 15 million degrees and not in the outer layers.
What is responsible for the mottled appearance of the Sun’s surface known as granulation?
extremely hot and extremely thin. Which of these best describes the photosphere? The disk of the Sun that we see. What is responsible for the mottled appearance of the Sun’s surface known as granulation? convection currents.
How do astronomers observe the sun?
The sun is a mass of ionized gas which goes by the fancy name of plasma — like in plasma TVs. With these telescopes solar astronomers can derive information about the solar plasma like its temperature and motion. Essentially we can monitor the weather on the sun.
What do astronomers study?
Astronomy is the study of everything in the universe beyond Earth’s atmosphere. That includes objects we can see with our naked eyes like the Sun the Moon the planets and the stars . It also includes objects we can only see with telescopes or other instruments like faraway galaxies and tiny particles.
Why does the sun emit neutrinos?
Neutrinos are born during the process of nuclear fusion in the sun. In fusion protons (the nucleus from the simplest element hydrogen) fuse together to form a heavier element helium. This releases neutrinos and energy that will eventually reach Earth as light and heat.
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.
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.
How do astronomers learn what elements are present in a given star?
Thus astronomers can identify what kinds of stuff are in stars from the lines they find in the star’s spectrum. This type of study is called spectroscopy. … From spectral lines astronomers can determine not only the element but the temperature and density of that element in the star.
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.
How does the chromosphere work?
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.
Can we see the chromosphere of the Sun?
What is the chromosphere responsible for?
Situated between the cooler photosphere below and the scorchingly hot corona above the chromosphere is responsible for transferring heat between these two layers. As a consequence the chromosphere’s temperature increases the closer it gets to the corona.
What does the chromosphere contribute to the solar spectrum?
A wavelength of 656.3 nm is in the red part of the spectrum which causes the chromosphere to have its characteristic reddish colour. By analysing the spectrum of the chromosphere it was found that the temperature of this layer of the solar atmosphere increases with height in the chromosphere itself.
What is the difference between the photosphere and the chromosphere?
When astronomers detect the Zeeman effect What do they know about the gas that is emitting or absorbing the light?
When astronomers detect the Zeeman effect what do they know about the gas that is emitting or absorbing the light? It is located in a magnetic field. Rank the following layers of the solar interior in order from the outermost to the innermost: convective zone core radiative zone.
What does the granulation tell us about the layers below the photosphere?
What does the granulation tell us about the layers below the photosphere? Since granules on the sun’s photosphere are constantly growing and shrinking astronomers can assume that convection currents are happening below it where the gas rises and falls due to heat.
Which of the following is evidence that granulation is caused by convection below the photosphere?
Which of the following is evidence that granulation is caused by convection below the photosphere? The centers of granules are rising and their edges are falling. Why are sunspots cooler than the photosphere?
How do astronomers know what the outer layers of the Sun are made of?
