Electromagnetic black hole

In the case of artificial black hole, not the severity needed to achieve the effect absorbent. And all thanks to artificial materials that are unusual electromagnetic properties resulting from its own structure and not its composition. King Chang and Tie Jun Cui, the State Key Laboratory of Millimeter Waves, from Nanjing University in China, designed and manufactured the artificial black hole, officially named unidirectional electromagnetic absorbed met materials using 60 strips,

The flow of black hole radiation prevents

An international team of scientists, with Spanish participation, has quantified the relationship between star formation rate and the power generated by black holes in centers of galaxies. The study, published this week in the journal Nature, comes a time when the flow of black hole radiation prevents the formation of more stars.The blue dots correspond to active galaxies, emitting X-rays detected from the Herschel Space Observatory of ESA. Image: ESA / NASA / CXCIn the center of large galaxies is usually a black hole and its presence influences the stars who live around them. Now an international team of research involving the Canary Islands Astrophysics Institute (IAC) and other Spanish-described in Nature the physical relationship between them and the rate of star formation around the so-called 'active galactic nuclei' (AGN, for its acronym in English). 

"The relationship between these two factors suspected for years, but in this work we have clearly identified for the first time," said Dr. Antonio SINC Cava.One of the most energetic phenomena in the universe is the growth of a black hole. In the center of the galaxy emits radiation that dominates the observable generated by stars at almost any wavelength. For measuring the star formation, scientists have analyzed the sky in wavelength sub-millimeter from the Herschel Space Observatory of the European Space Agency.

One space observatory captures the perseverance of a star into a black hole. A team of researchers has found a black hole at the moment which a possible thanks to the Swift space observatory for NASA. 

"Until now, this is a unique event. Although it has long been expected that such phenomena should occur, the glow it emits is a surprise.  A researcher at Pennsylvania State University and coauthor of the published the latest issue of the journal Nature.One space observatory captures the perseverance of a star into a black hole.

Scientists have determined that the black hole is at the center of a galaxy at a distance such that the light of this phenomenon took about 4 billion years to reach us. 

Black holes are common in the center of galaxies. The Milky Way is home to one of about 2 million times the mass of our Sun Its powerful gravitational fields create strong gradients that can destroy the stars who spend many millions of miles of it and produce a flash of ultraviolet light and X rays . 

"It's what we think happened to the star absorbed in this case. The result of this process may have noticed on several occasions, but so far never been seen beginning.
