Verification a new supernova black hole


In space telescope NASA "Swift" fixed-ray flashes, indicating the discovery and the survival of a new black hole, which was previously unknown. It is located at 20-30 thousand light-years from Earth. Flash X-ray peak of the supernova occurred on September 18. Flash output is 10 thousand volts, but two days of observation exposed that the radiation has increased by 30 times.

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.

X-Rays from Young Supernova Remnant Discovered


Astronomers have detected X-rays from the leftovers of a supernova that was first seen from Earth over 50 years ago. This supernova SN 1957D was call because it was the fourth one detected in the year 1957. Whilst detected in the radio and optical for decades, SN 1957D did not appear in previous X-ray images.

Tracking with Chandra


In this study, researchers focused Chandra to a given parcel of the cosmos, for more than six weeks, to the Chandra Deep Field South called (CDFS). This region, located in the so-called constellation Fornication, is the deepest X-ray exposure ever produced.These images showed that young black holes grew in the early stages of the universe, more aggressive than has hitherto been believed, and while growing up that staying galaxies (or their host galaxies).
