... Supernovae physics (from Wikipedia ): A supernova is a stellar explosion that creates an extremely luminous object that is initially made of plasma ionized form of matter. ... The explosion expels much or all of a star's material at a velocity of up to a tenth the speed of light, driving a shock wave into the surrounding interstellar gas. ... Working on a time series of images in the Large Magellanic Cloud he detected a flaring star, possibly a supernova located in a distant galaxy behind the LMC. ...

SN 2008gy is found to be located far outside the boundaries of the three nearest galaxies, each of them has a nearly equal probability to be the host galaxy. ...

... The Galactic low-mass X-ray binary GS 2023+338 was discovered during the burst on May 22, 1989 with the Japanise satellite Ginga (aka Galaxy). The flux reached 17 crabs (this unit of flux measurement is an bright X-ray source, Crab Nebula) at 10-35 keV. ... No other radio telescope worldwide carried out multi-frequency measurements. ... Upon 14 days the radio flux fell below the detection level at the RATAN-600 in relation to the decrease of the X-ray flux. ...

... The project assumes creation of an international space observatory - the interferometer "Earth - Space - Space" in order to perform of astronomical investigations in millimeter, submillimeter and infrared regions with extremely high sensitivity (to a few nanoJanskies units of flux density in continuum spectrum) and extremely high angular resolution (to a parts of microsecond of arc or, possibly, nanosecond). ... radio-interferometric channels of the system "Space - Space", region 0.2 - 3 mm; . ...

... Special Reports Giant space cloud may be powered by black holes 17:57 23 April 2007 NewScientist.com news service David Shiga An enormous cloud of roiling plasma in space may be drawing its energy from black holes, new observations suggest. Such clouds might be sources for the mysterious particles that occasionally crash into Earth's atmosphere at ultra - high speed. ... But higher energy particles in the cloud may be able to escape, he says. ...

... X-ray sources in galaxies: active nuclei, primodal black holes or microquasars . The last findings in observations of point-like X-ray sources in galaxies are reported. ... A new class of objects has been discovered - the Ultraluminous X-ray (ULX) sources, which could be as black holes of intermediate mass (100-1000 suns), being captured by galaxies and spiralling in because of dynamical friction, or microquasars (SS433-like stars), being orientated "face-on". ...
