To this day, we do not have a deep knowledge of the sun, the energy center of life on Earth. There is still no clear answer as to why the solar corona is hotter than the Sun’s surface. That is, the surface of the Sun is cooler than the corona. NASA’s Marshall Grazing Incidence X-ray Spectrometer has been launched to answer these critical questions.

Although there have been soft X-ray spectrometer missions in the past, they have not been able to record the energy distribution in the Sun’s corona. At the same time, NASA hopes that MaGIXS will be able to gather crucial information about the heat distribution in the Sun’s corona. This information may help to determine when and how often the sun’s corona heats up.


The gaseous part of the Sun’s outer surface is called the atmosphere. The corona is the outermost part of the Sun’s atmosphere. Due to the strong light from the sun, the corona does not appear normally. Therefore, special equipment is needed to monitor the sun’s corona. At the same time, during a total solar eclipse, the Sun’s corona appears when the Moon forgets the major parts of the Sun.

If the heat decreases as you move away from the fire, the reverse happens in the case of the sun. The question that confuses the scientific world is why the corona is many times hotter than the surface of the sun where fission occurs. If the Sun’s temperature in the corona is 18 million degrees Fahrenheit, then the surface temperature of the Sun below 1000 miles is only 10,000 Fahrenheit.
