Alien starts with "in space you can't here a sound" I wonder if we could. Watch the gigantic energic burst out on the sun surface, wat kind of sound will this create. Sunspots are dark areas in the Sun's photosphere, which are cooler than their surroundings. They generally appear in pairs or groups, and are associated with very strong magnetic fields. Spot sizes vary from "small" ones about 15,000 km across (that is, about the size of the Earth) to enormous groups spanning more than 150,000 km. Most of them have a dark central region called the "umbra" (that is about 1600 degrees cooler than the photosphere), surrounded by a less dark region called the "penumbra" (about 500 degrees cooler than the photosphere). Wow, and I illustrate this with UF4.1, just a suggestion. Enjoy, have a sunny day.
