This is What 43,000 Galaxies Look Like On a Map [Science]

The image above is the most complete map of our local universe to date. It took more that ten years to create, has 43,000 galaxies and extends out 380 million light years from the earth. The 3D coordinates of each galaxy was recorded so the raw data could potentially be used to build a realistic 3D model of the universe. Throw in some holographic technology and you have something straight from Star Trek. More »


The quantum computer is growing up

A general rule in data processing is that disturbances cause the distortion or deletion of information during data storage or transfer. Methods for conventional computers were developed that automatically identify and correct errors: Data are processed several times and if errors occur, the most likely correct option is chosen. As quantum systems are even more sensitive to environmental disturbances than classical systems, a quantum computer requires a highly efficient algorithm for error correction.
