Team Maps Dark Matter In Startling Detail

"Clues revealed by the recently sharpened view of the Hubble Space Telescope have allowed astronomers to map the location of invisible 'dark matter' in unprecedented detail in two very young galaxy clusters. The team's results lend credence to the theory that the galaxies we can see form at the densest regions of 'cosmic webs' of invisible dark matter, just as froth gathers on top of ocean waves, said study co-author Myungkook James Jee, assistant research scientist in the Henry A. Rowland Department of Physics and Astronomy in Johns Hopkins' Krieger School of Arts and Sciences." [Link]
