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.

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.

See the cosmos 24 hours a day


Forthcoming astronomy is now possible, thanks to virtual planetarium that is installed in the Mall yesterday Arousa until 4 November. A journey during the cosmos and enjoy the most famous constellation or the operation of the solar system.

Curiosity log 15 (playing in Rocknest)


Curiosity is already near the area known as Glenelg. On October 2 (Sun 56) arrive at the area known as Rocknest, where there are some small sand bank. Curiosity will spend two or three weeks at this site while making the first sample collection with robot arm systems. As of today, our rover has already surpassed the 400 runs, which is not bad.
