Astronomers discover giant cosmic sheet around the Milky Way
Nearly a century ago, astronomer Edwin Hubble discovered that almost all galaxies are receding from the Milky Way. Using advanced computer simulations, the researchers discovered that the matter surrounding the Local Group is arranged in a broad, flattened structure that stretches tens of millions of light-years across. According to lead researcher Ewoud Wempe, the study represents the first detailed attempt to determine the distribution and motion of dark matter in the area around the Milky Way and Andromeda.
