Australia has built a powerful new telescope

Australia celebrates the finishing point of construction the telescope, which is considered the most powerful telescope for radio survey in the world. The Australian Square Kilometer Array Pathfinder (ASKAP) will give astronomers an unprecedented opportunity to look at black holes, gas clouds from which stars form, and "unusual objects that are on the edge of our understanding of the physical laws of the universe," said astrophysicist Brian Boyle (Brian Boyle) Organization of Australian Scientific and Industrial Research of the Commonwealth.

New X-ray discovered a new black hole

In mid-September, a space telescope, "Swift" has found a rare celestial phenomenon - a new X-ray, the appearance of which specify the presence of previously unknown black hole (BH) of stellar mass.

The facility is named Swift J1745-26 in accordance with its coordinates in the sky, and the new is a few degrees away from the center of our galaxy in the direction of the constellation Sagittarius. While astronomers to calculate the exact distance to the object, but they suggest that it is from us at a distance of 20,000 to 30,000 light-years away in the inner region of our Milky Way galaxy.

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.
