The Sun is Heating Up

Don't forget the sun is like other stars. It is not a static body in the heavens.

Recent evidence, however, suggests that we don't know all there is to know about the nearest star. Drs. David Gray (University of Western Ontario) and William Livingston (Kitt Peak) have been studying the Sun's temperature with a technique that compares the strength of absorption lines in the solar spectrum. Gray finds that in addition to a fluctuation of 1.5 degrees Kelvin over the 11-year cycle, the temperature of the sun is steadily increasing by 0.014 degrees/yr.

Just something to think about.
