Explanation:
Sometimes the Sun's surface becomes a whirlwind of activity.
Pictured is a time-lapse video of the
Sun's surface taken over a two hour period in early May, run both forwards and
backwards.
The Sun's surface was blocked out so that
details
over the edge could be imaged in greater detail.
Hot plasma is seen swirling over the
solar
limb in an ongoing battle between changing
magnetic fields and constant gravity.
The featured
prominence rises about one
Earth-diameter over the Sun's surface.
Energetic events like
this are becoming less common as the Sun nears a minimum in its
11-year activity cycle.
