It is typically only seen during a solar eclipse or through the use of special telescopes on satellites. The temperature of the chromosphere varies substantially with height above the photosphere.
During which event is the chromosphere visible?
It is only seen during total solar eclipses, or with sophisticated telescopes, and its red and pinkish color gives the blackened moon a thin halo of color against the greyish corona further out, hence its name ‘chromo’ sphere.
Is the chromosphere of the Sun visible from Earth at all times?
The chromosphere of the Sun is visible from Earth at all times, except during total eclipses.
Is the chromosphere heated by the corona?
The sun’s 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.
Where is the chromosphere?
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).
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.
What happens in chromosphere?
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).
Where is the chromosphere of the Sun quizlet?
Where is the chromosphere on the Sun? It is the layer above the visible surface of the Sun.
How hot is the chromosphere?
the chromosphere is the innermost atmospheric layer. It is just above the photosphere. Here the temperature begins to rise again, to about 36,000 degrees F. Above the chromosphere is the transistion layer, where temperatures increase 6000 to over half-a-million degrees.
How was the Sun’s chromosphere discovered?
The chromosphere of the Sun observed through a telescope with a filter that isolates the H-alpha emission. The most prominent structures in the chromosphere, especially in the limb, are the clusters of jets, or streams, of plasma called spicules. Spicules extend up to 10,000 kilometres above the surface of the Sun.
Why is it hard to observe the chromosphere?
The chromosphere is difficult to see without special equipment because the light from the much brighter photosphere washes it out. It has a reddish color, but you can only really see it during a total solar eclipse. … These are fingers of gas that kind of look like grass growing on the surface of the Sun.
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 chromosphere in chemistry?
Definition: Chromosphere is a reddish and glowing layer of gas above a star’s (or Sun’s) photosphere. It is actually the transition between corona and the photosphere.
What is the solar chromosphere?
The solar chromosphere (color sphere) is a strongly structured and highly dynamic region (layer) of the Sun’s atmosphere, located above the bright, visible photosphere. It is optically thin in the near-ultraviolet to near-infrared spectral range, but optically thick in the millimeter range and in strong spectral lines.
When the chromosphere is seen it is sometimes seen as a dim pink color what causes this color?
It is seen during total solar eclipses near the edge of the solar disk. They look pink because of the three hydrogen Balmer lines.
When we glimpse the chromosphere at the start and end of totality Its color is quizlet?
When we glimpse the chromosphere at the start and end of totality, its color is: red, due to ionized hydrogen at lower pressure. The percentage (by number of atoms) of the Sun that is Hydrogen is about: 91%.
Where does hydrostatic equilibrium exist in the Sun?
Hydrostatic Equilibrium: In the interior of a star, the inward force of gravity is exactly balanced at each point by the outward force of gas pressure. The mutual gravitational attraction between the masses of various regions within the Sun produces tremendous forces that tend to collapse the Sun toward its center.
Which is used observationally to determine the age of a star cluster?
massive blue main sequence stars. … Which is used observationally to determine the age of a star cluster? the luminosity of the main sequence turn-off point (probably on test) You observe a low-mass helium white dwarf.
Why can the chromosphere and corona only be seen from Earth during an eclipse?
Remember, the sun has multiple outer and inner layers. Its outer layers are the photosphere, corona, chromosphere, and the transition region. … Because of the light emitted from the sun’s photosphere, without help from a coronagraph, the corona is only visible by sight from Earth during a total solar eclipse.
During what event can we observe both the corona and the chromosphere?
A total solar eclipse presents a rare opportunity to observe the corona and chromosphere, the two outer most layers of the sun’s atmosphere. Under normal circumstances, the bright yellow surface of the sun, called the photosphere, is the only feature we can observe.
Why is chromosphere red?
The chromosphere appears red because of the large amount of hydrogen present. You can see this red color at the very edge of the Sun during a total solar eclipse. … These gigantic plumes of gas are trapped by magnetic fields above the photosphere, reaching altitudes of 150,000 km above the Sun.
What heats the chromosphere and corona to a high temperature?
How do astronomers think the solar chromosphere and corona gets heated to their high temperatures? Magnetic fields carry heat outward from lower layers.
When was the sun’s chromosphere and corona discovered?
English astronomer Norman Lockyer identified the first element unknown on Earth in the Sun’s chromosphere, which was called helium. French astronomer Jules Jenssen noted, after comparing his readings between the 1871 and 1878 eclipses, that the size and shape of the corona changes with the sunspot cycle.
