Last year, an instrument aboard the Solar and Heliospheric Observatory (SOHO) spacecraft dazzled solar physicists by finding oxygen ions in the sun's corona at temperatures of 100 million degrees Celsius--many times hotter than expected. In an upcoming issue of Solar Physics, the team that operates SOHO's Ultraviolet Coronagraph Spectrometer drops another bombshell: a strong hint of the mysterious mechanism that generates these sizzling temperatures and, in so doing, drives the solar wind (see main text).
