An artist's concept of a black
hole, surrounded by an accretion disk. The gas in this disk is heated to
millions of degrees Celsius and emits X-ray radiation.
The hefty black hole lies at the center of the galaxy NGC 3516, which is
about 100 million light years away in the direction of the Big Dipper.
Calculations involving Einsteinís general relativity showed that this
object, the black hole, weighs between 10 and 50 million solar masses.
Introduces Holographic 360-Degree 3D Imaging System - SpaceDaily 3Dsolar
display devices are set to transform the way individuals experience
multimedia content both at work and home. For the very first time,
computer users will be able to view 3D objects hovering a few inches
away from a screen that rotates 380 degrees - without wearing glasses.
The notable feature is the way users will be able to manipulate the
virtual image directly with their hands as they would a real object. "3Dsolar
is light years beyond holography and autostereoscopy in that designers
can create images that are highly detailed in color, design and
animation," said Patrick Levy Rosenthal, inventor of 3Dsolar.
