“A balloon-borne instrument soaring high over Antarctica has found evidence of a possible large clump of mysterious so-called dark matter relatively close to our solar system, scientists said on Wednesday. … Scientists think perhaps 25 percent of the universe is made up of dark matter, which responds to gravity the same way as does regular matter such as stars and planets and the like. While the stuff is thought to be strewn throughout the cosmos, it is invisible and poorly understood. Scientists have struggled to find any solid evidence of dark matter, and the new study could represent a major step forward in that effort.” (11/19/08)
