Blazing flow

They have found the research teams is that the accretion-growth by the addition of materials of the star that has been affected by the absorption of the black hole, relativistic jet has occurred, a result not predicted by the theoretical models to observation. 

When we refer to scientists relativistic jets, means that the particles of the jet of matter are moved close to the speed of light. For these speeds you need to use the theory of relativity Einstein (hence the term 'relativistic') to describe  the physics of the reaction. Newtonian classical physics does not work at these speeds. That is, the material in the jet is moving very fast, about a billion miles an hour Kennel.

Photonic Structures mass 3-D

However, gallium arsenide has to be applied in this case in complex three dimensional structures, through an epitaxial approach which eliminates many of the defects introduced by traditional manufacturing methods, opening a promising way for the creation of photonic structures mass 3-D.

 Another advantage of this new system is the ease of creating on the through different layers. With sudden changes may be possible to vary the materials introduced in the photonic crystal, enabling new applications and uses for these devices. 

 To test their technique, the research group at the University of Illinois at Urbana-Champaign built a 3D photonic crystal LED, the first device of this type for this class of applications. Now, engineers and researchers work to optimize the structure specific applications in mind. 

A heavyweight galaxy

Instead, Minchin believes the arm of NGC 4254 stars was created by the very seriousness of VIRGOHI21. He reached this conclusion after studying the object with the Westerbork Synthesis Radio Telescope-(WSRT) in the Netherlands, which detects the emission of hydrogen atoms. Observe an animation showing VIRGOHI21 and two galactic neighbors from a variety of perspectives .

'Dark Galaxy' continues to astronomers

The Hubble Space Telescope has failed to reveal the expected number of stars in the mysterious cloud of hydrogen on the size of a galaxy known as VIRGOHI21.

The research reinforces the idea that the gas cloud is the only known example of a "dark galaxy" that never initiates the birth of a star.

It is thought that a galaxy is formed of normal matter, or which has collected in clouds of hypothetical dark matter. But scans have shown fewer galaxies than expected, suggesting that, for unknown reasons, 

Galaxy of Dorian Gray

NASA has made some observations about the galaxy called "I Zwicky 18", ruling out the possibility that it is a young galaxy in the nearby universe, as was believed until now.  It can actually be considered an adult, that looks young and that resembles galaxies typically found only in the early Universe.  However, Hubble has found faint stars, older within this galaxy, suggesting that "I Zwicky 18" may have formed while many other galaxies .

The black hole of the Milky Way

Japanese astronomers has discovered that the black hole in the center of our galaxy unleashed a powerful blast for three centuries, thanks to observations with the ESA observatory XMM-Newton and other X-ray satellites and NASA Japanese.  This discovery helps solve a longstanding mystery: why the black hole of the Milky Way is so inactive.  This black hole, known as Sagittarius A-star (A *), is truly massive, contains about four million times the mass of our Sun, the energy radiated from its surroundings is billions of times weaker than the emitted from central black holes in other galaxies. 

Origin of Astronomy

Astronomy of Egypt and other ancient civilizations.  Everything is repeated in the sky above us: every night and come back a star, moon phases change, the sun finds its way between the stars.  Rather, these laws were first discovered by astronomers, who sat at the primeval fire.  The motion of the moon (or more accurately, the frequency shift of the lunar phases) was used as the basis of the first lunar calendar,
