Huge loops of very hot, electrified gas rising above the Sun's surface vibrate with enormous energy at times of solar storms, like the strings of an immense guitar. This is the latest surprise from a flotilla of spacecraft -- the Solar and Heliospheric Observatory (SOHO), Ulysses, and the four Cluster satellites -- with which scientists are trying to make sense of how disturbances on the Sun affect the Earth. The vibrating loops are a new piece in the complex puzzle of solar storms, revealing intense, local, and short-lived activity of a kind that had escaped the scientists' notice. Dr. Werner Curdt of Germany's Max-Planck-Institut für Aeronomie reported on the solar vibrations this week, at a scientific meeting on the Greek island of Santorini. He is in charge of an instrument on SOHO called the Solar Ultraviolet Measurements of Emitted Radiation (SUMER), which can measure the speeds of electrified gas structures moving in the Sun's atmosphere. SUMER has seen many hot loops, invisible to other instruments, which sway from side to side. After careful study, the scientists investigating them are now sure that the vibrating loops play a key role in the Sun's most violent activity. For the complete
