Astronomers Map Dark matter Halo

Jul 25, 2003 - Two Canadian and a US Astronomer have created a detailed map of the Halo of Dark matter that seems to surround all galaxies. The mass of Dark matter accounts for 50 times the mass and five times the size of the light-producing material in a galaxy. This flattened sphere-shaped Halo was seen by measuring how the gravity from a closer Galaxy bends the light from a distant object that passes behind it; a technique called gravity lensing.
