Hubble makes 3D dark matter map
-------------------------------------------------------------------------------------------------------------------

Astronomers have mapped the cosmic "scaffold" of dark matter upon which stars and galaxies are assembled.

some snippets from the full story, to get your mouth watery:
"[The study] involved nearly 1,000 hours of observations with the Hubble Space Telescope."

"Ordinary matter - gas, stars, planets and galaxies - makes up just one-sixth of all matter in the Universe. The remainder is unseen. "

"To reach us, the light from galaxies has to pass through intervening dark matter."

This dark material bends light in much the same way as light is bent when travelling through a lens."
