MessageToEagle.com - Moving holograms have long been considered science fiction, but now with new technology
emerging you will soon be able to see how holograms do almost everything, from watching TV, playing chess, walking
the dog or even talking to you, giving you advice.
Holographic technology is not as new as many people think. The first holograms were invented by Dennis Gabor in 1947.
He was trying to find a method for improving the resolution of electron microscopes.
Unfortunately, Gabor had no access to lasers which are necessary fro creating and displaying good holograms.
Instead, Gabor experimented with a mercury vapor lamp, which produced monochrome blue light, and filters made
his light more coherent.
Gabor won the Nobel Prize in Physics for his invention in 1971.

Ever since Gabor made his first attempts to create holograms, scientists have constantly worked on improving this technology.
Today, thanks to a breakthrough in 3D holographic image technology, it is possible to watch a projection of a three-dimensional moving image without the need for special eyewear such as 3D glasses or other auxiliary devices.
This new holographic telepresence has been developed by optical sciences professor Nasser Peyghambarian and his team at the University of Arizona.
"Holographic telepresence means we can record a three-dimensional image in one location and show it in another location, in real-time, anywhere in the world," said Peyghambarian, who led the research effort.

Holographic telepresence technology can be used in a variety of areas such as telemedicine, advertising, updatable 3D maps, and entertainment.
"Surgeons at different locations around the world can observe in 3D, in real time, and participate in the surgical procedure."
"The system is a major advance over computer-generated holograms, which place high demands on computing power and take too long to be generated to be practical for any real-time applications."
For the time being the telepresence system can present in only one color, but professor Peyghambarian and his colleagues are now working on a multi-color version which will be available in the near future.

The star's existence raised at once many questions for scientists.
The object is definitely not as its "contemporaries" that appeared immediately after the Big Bang event.
Have you ever wondered what the Universe will look like for a future alien astronomer?
NGC 5907 is sometimes called the "Splinter" or Knife Edge Galaxy because of its unusual appearance.
It is a spiral galaxy lying in the Dragon constellation,
about 40 million light-years from Earth that could have been formed through a gigantic collision of galaxies, 8 to 9 billion years ago.
The Milky Way is hard to map because we are sitting on the edge of the galaxy looking through it.
However, we know that spiral galaxies like the Milky Way have magnetic fields that follow a particular pattern so we were able
use polarised light to map the magnetic fields...
