where do the elements in the outer layers of the sun come from

0 1

From far away, the cloud looks as if it has a sharp surface, but you do not feel a surface as you fall into it. The corona is the outer atmosphere of the Sun, which is much larger in volume than the Sun itself. The convective zone is the outermost layer of the solar interior. The bright granules are columns of hotter gases rising at speeds of 2 to 3 kilometers per second from below the photosphere. In 2013, NASA launched the Interface Region Imaging Spectrograph (IRIS) to study the transition region to understand better how and why this sharp temperature increase occurs. (credit: modification of work by NASA/Goddard), This photograph shows the photosphere—the visible surface of the Sun.

The outermost part of the Sun’s atmosphere is called the corona. In the seventeenth century, several observers described what appeared to them as a narrow red “streak” or “fringe” around the edge of the Moon during a brief instant after the Sun’s photosphere had been covered. Except where otherwise noted, textbooks on this site Although this sounds like a lot, it’s so trivial compared to the enormous mass of the Sun that it can be neglected as we study the Sun. Today, students are probably most familiar with it as the light gas used to inflate balloons, although it turns out to be the second-most abundant element in the universe. Where did these elements come from?

The core is approximately 20% of the size of the solar interior and is thought to have a temperature of approximately 15 million K, making it the hottest part of the Sun. The Sun’s layers are different from each other, and each plays a part in producing the energy that the Sun ultimately emits. The core has a radius of 750 miles.
