February 15, 2007
For the first time, astronomers have collected and analyzed a long-term set of activity and brightness measurements of a "solar twin." Researchers announced today that the close solar analog, 18 Scorpii, exhibits brightness changes over the course of its activity cycle that are nearly identical to the Sun's.
