We live in a pale-green universe. That's the conclusion of researchers who analyzed the colors of some 200,000 galaxies as part of the largest galaxy survey completed to date.
The survey mapped the brightness and distances of galaxies in two giant swaths that together cover 5 percent of the sky. From those data, Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore and an international group of colleagues constructed what they call the cosmic spectrum.
