APOD 1.4


This image of the sun was taken in 2002 and it shows how the sun has so many chemical reactions at once that it can create these types of surface craters of boiling matter. Some of these sunspots can get as big as 50,000 miles in diameter. The Earth isnt even as big as some of these sunspots on the sun. Some of these events that take place on the sun are signs of how the sun is becoming more and more sensitive every year. It is estimated that the sun will die out in about 5 billion years. Thses obsvervations will help us to understand more about how the stars in the universe develop over time and about the stages they go through.
