A Partial Eclipse of an Active Sun
Explanation: Watch for three things in this unusual eclipse video. First, watch for a big dark circle to approach from the right to
block out more and more of the Sun. This dark circle is the
Moon, and the video was made primarily to capture this
partial solar eclipse last week. Next, watch a
large solar prominence hover and shimmer over the
Sun's edge. A close look will show that part of it is actually
falling back to the
Sun. The prominence is made of hot
plasma that is temporarily held aloft by the
Sun's changing magnetic field. Finally, watch the Sun's edge
waver. What is
wavering is a dynamic carpet of
hot gas tubes rising and falling through the
Sun's chromosphere -- tubes known as
spicules. The entire 4-second
time-lapse video covers a time of about ten minutes, although the Sun itself is expected to
last another 5 billion years.
