Universe Today - Dark Matter Maps

Summary: What's the Universe made of? Don't worry if you don't have a clue, astronomers don't either. The Universe is dominated by a mysterious dark matter that seems to form the true mass of a galaxy, not the regular matter - like stars and planets - that we can actually see. Dr. James Jee from Johns Hopkins University used the Hubble Space Telescope to create a detailed map of dark matter concentrations around two galaxies. And astronomers just got some new clues.
