Sun is the biggest object of our solar system, and we all know how important sunlight is for us, what? The sun can be tested by the sun's rays, yes, because NASA scientists observe the sun at different wavelengths. When a photograph of the sun was taken with a standard camera, this familiar image shows a yellow, featureless disk that would have a red wavelength when the sun's rays entered the Earth's atmosphere, because it would be The pass loses blue wavelength.
The sun can, in fact, emit its light in all colors, the sun's yellow is the brightest wavelength, because it is the color we see with our naked eyes, and it also represents the camera. Scientific tests are carried out from the Earth by special instruments, in space telescopes, observing the light beyond the limits, visible with the naked eye, and sciatic about different components of the sun's surface and atmosphere from different wavelengths. Information comes out, scientists use them to paint the whole picture of different stars.
As we can see in the image, that colors float around the sun, we should note that the same area of the sun looks different, as each wavelength of light represents the solar material at a specific temperature. We can extract information from wavelengths using two methods, one way is that by using a spectrometer, we can observe and measure multiple wavelengths of light simultaneously. And the same we can use the ranges, all around the sun On the other hand, temperature and material display, it helps to form a composite.
The second approach is that SDO scientists have chosen 10 different wavelengths to observe for their atmospheric imaging assembly (AIA) instrument, and each wavelength is largely based on a single, and two, type of ions Is, scientists chose each wavelength to illuminate a particular part of the sun's atmosphere.
4500: showing the sun's surface or photosphere.
1700: show, the surface of the sun is a layer of the sun's atmosphere called the chromosphere, which lies just above the photosphere and is also where the temperature starts rising.
1600: show's A mixture between the upper photosphere and what is called the transition region, a region between the chromosphere and the uppermost layer of the sun's atmosphere is called the halo, The transition zone is where the temperature rises rapidly.
304: This light is emitted from the chromosphere and the transition region.
71: This wavelength represents the sun's atmosphere, or corona, when it is cool. It shows a slightly warmer area of the corona, and also much warmer material of a solar flare.
211 :: This shows the wavelength of the hot, magnetically active fields in the sun's corona.
335 It also has giant magnetic arcs coronal loops Shows known as .
193: also shows the wavelengths of hot, magnetically active fields in corona
94: This highlighted areas of the corona during a solar flare.
131: The hottest material in a flare.
