A ring of asteroidal dust encircles the Earth, and a cloud of dust permanently follows the Earth in its orbit around the Sun, according to new infrared satellite observations reported in the June 29 issue of Nature. The findings by astronomers at the University of Florida, Gainesville, may also help explain the asymmetry of the zodiacal cloud that ...
