APOD 1.1

August 28, 2010. Hole in the Sun.


This picture stood out to me as an immediate choice as its unique view of our sun which looks as though there is a gaping hole going through its center.  The hole is called a coronal hole, an area of little density and cool temperature.  I learned that this coronal hole is formed by a magnetic field that allows for higher density plasma matter to exit via the hole.  One common effect of such an experience is that if the coronal hole is facing the Earth, it may create strong solar winds on our planet.  This is also the cause of the X-Rays that we can detect from the sun from the light spectrum.
