Using NASA's x-ray telescope Chandra at the core of a spiral galaxy NGC 4178 type SBcd located at 55 million light-years from Earth in the constellation Virgo, found a bright x-ray source, which astronomers believe a black hole with a mass of just VAC 104-105 Solar masses. This is the most low-mass of the supermassive black holes (SMCG)observed in the centers of spiral galaxies.

Scientists from the Institute of data storage at the Singapore Agency for science, technology and research (A*STAR) conducted a simulation work hard disks existing types in more bit densities. It turned out that the information recording on a single magnetized microsemi hard drive (instead of the group of tiny grains) will not only degrade the reliability of storage of the information, but will even increase it, in this case, of course, dramatically increasing the amount of hard drive.

Dinosaurs among us. We call them birds. At least thinks most paleontologists. But where did the wings?

If the calculations of scientists will be correct, it will not help if this information to find the grave of the great conqueror?

An international team of astronomers for the first time for all history of space research has discovered exoplanet that orbits in the system of two pair of stars, one of which is located on the remote orbit. The planet is about five thousand light-years from Earth. The opening is made in the framework of the international program at Yale University Planet Hunters.
