Outlines of JVO project

Thanks to the progress of telescopic technology and the detection technique of recent years, it is expected that we will meet with a situation where a large scale of high-quality data is continuously generated by such as Subaru Telescope, Sloan Digtal Sky Surve an so on.

The traditional analysis way, however, appears to be insufficient for using the large amount of data effectively and efficiently and getting the maximum scientific results.

Although many people recognize the importance of statistical research that uses the multi-wavelength data, such research actually needs considerable effort.

On the other hand, the computational performance and the speed of the network is drastically improving, and for effective utilization of them different ways to use the resouces are beeing investigated in the field of informatics and the computer science and research.

Giving examples, the GRID technology that combines dispersed computer resources, the data mining technologies for discovering something new in the large-scale data base, and database technologies are examined.

We, National Astronomical Observatory of Japan, has developed a plan to establish an Japanese Virtual Observatory (JVO) which makes the digital universe in computers and through which we analyze (observe) the universe from various points of view, by combining effectively the astronomical and computation turning points.

We hope that this JVO project will make a great contribution to the evolution of astronomy of the 21st century.
