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).
