Clarification of the Milky Way's mass found more dark matter

A team of scientists from Japan initiate new, more accurate measurements of the distance from the solar system to the center of our galaxy, the Milky Way, which was found to be 26,100 light-years, and the rate of rotation of our galaxy near our solar system, which was found to be 240 km / s. Previous data on the speed of our galaxy is 220 km / s, which means that the mass of our galaxy - and especially the contribution, made ​​by dark matter - about 20% higher than previously thought.

Plenty of dark matter near the Sun

Astronomers at the University of Zurich, the ETH Zurich, the University of Leicester and NAOC Beijing have originated large Amounts of invisible "dark matter" near the Sun. Their results are reliable With the Theory That the Milky Way Galaxy is surrounded by a massive "halo" of dark matter, but this is the first study of its kind to use a ridicule method rigorously tested against high quality data from simulations.
