Astronomers have mapped the cosmic "scaffold" of dark matter upon which stars and galaxies are assembled.
Dark matter does not reflect or emit detectable light, yet it accounts for most of the mass in the Universe.
The study, published in Nature journal, provides the best evidence yet that the distribution of galaxies follows the distribution of dark matter.
This is because dark matter attracts "ordinary" matter through its gravitational pull.
Scientists presented details of their research during a news conference here at the 209th meeting of the American Astronomical Society (AAS) in Seattle, Washington.
At which, by the way, my step-daughter is presenting her work on "Spectroscopic Investigation of Companion Stars in Herbig AeBe Binary Systems" at Gemini Observatory, Chile.
According to one researcher, the findings provide "beautiful confirmation" of standard theories to explain how structures in the Universe evolved over billions of years.
