Knowledge is infinite. We’ll never know it all, thank goodness.
Open mind, open eyes, open heart.

The study,
presented this week at the Royal Astronomical Society’s National Astronomy
Meeting in Lancashire, England, reveals that the looping
magnetic fields
along the Sun’s outer regions, called the corona, carry
magnetic sound waves in a similar manner to musical instruments such as guitars
or pipe organs.
Robertus
von Fay-Siebenburgen of the Solar Physics and Space Plasma Research Center at
the University of Sheffield and his colleagues combined information gleaned
from sun-orbiting
satellites
with theoretical models of solar processes, such as coronal mass
ejections.
They found
that explosive
events at the Sun’s surface
appear to trigger acoustic waves that bounce
back and forth between both ends of the loops, a phenomenon known as a standing
wave.
