Helioseismology Tours
Helioseismology is a fancy way of saying that we
can learn about the Sun by "listening" to it. Astonomers listen to the
Sun's heartbeat to learn about the inside of the Sun, just like seismologists
learn about the interior of the Earth by "listening" to earthquakes. (But
for helioseismologists their job is a lot tougher: like figuring out how
a piano is made by listening to it fall down the stairs!)

What is helioseismology?
"Helioseismology
utilizes waves that propagate throughout the Sun to measure the invisible
internal structure and dynamics of a star." This overview gives a summary
of what helioseismology is and how it is done. By Dave Armet (GONG)

Helio- and Asteroseismology
A multimedia tour through the sound waves of
the sun. Listen to the Doppler shift of an ambulance, trace the annimated
reflection pattern of sounds waves bouncing inside the sun, and discover
what the world of helioseismology is all about! Created by Aarhus
University, Aarhus, Denmark.

Song of the Sun
"The Sun is playing a secret melody, hidden inside
itself, that produces a widespread throbbing motion of its surface. The
sounds are coursing through the Sun's interior, causing the entire globe,
or parts of it, to move in and out, slowly and rhythmically like the regular
rise and fall of tides in a bay or of a beating heart." (Quote by Kenneth
R. Lang)

Solar Activity Predictions
Have you ever wanted to be a Sun "weather announcer?"
To predict solar activity you'll need to know some physics. Peruse this
site for techniques on long-term activity forecasts as well as pointers
to other sites which try to predict activity.
