Scientists create dark matter 'map' to see invisible space
We've finally gotten our first glimpse at the mysterious material that supposedly makes up 27 percent of the universe. It's only taken two years of research, the efforts of 300 researchers working for the Dark Energy Survey (DES) and a 570-megapixel camera attached to the Victor Blanco telescope in Chile to do so. Their findings, in the form of a map, are expected to be released at a meeting of the American Physical Society tomorrow. Well, "map" is a bit of a misnomer dark energy can only be observed indirectly, through the lensing effect that it has on stars and galaxies.
