Ontario: Astrophysicists have created a 3D map of the universe that spans nearly two billion light years and is the most complete picture of our cosmic neighbourhood so far. The spherical map of galaxy super clusters will lead to a greater understanding of how matter is distributed in the universe and provide key insights into the mysterious dark matter, the researchers noted.
The galaxy distribution is not uniform and has no pattern. The lighter blue and white areas on the map represent greater concentrations of galaxies. The red area is the supercluster called the "shapley concentration", the largest collection of galaxies in the nearby universe. Unexplored areas appear in medium blue.
Scientists have observed that galaxies move differently because the universe's expansion is not even. These differences are called peculiar velocities. Our own Milky Way galaxy and its neighbour Andromeda are moving with a speed of two million km per hour.
