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.

Find the nearest star to the central black hole in the galaxy

An international team of researchers, with Spanish contribution, has found the closest star to Sagittarius A *, the black hole four million times the mass of the Sun located in the center of the Milky Way. It is the star S0-102; it takes 11.5 years to complete one orbit around the black hole. The work will know how to operate the law of gravity in extreme environments, according to the journal Science.

A geological mystery is revealed by Opportunity

Spherical objects focused on a projection that Opportunity reached fluctuate in several aspects of the iron-rich spherules nicknamed "blueberries" that the rover found in its place of landing in early 2004 and in many other places so far.
