Maraghe observatory was built by such engineers as Moayiededdin Orozi etc. under supervision of Khaje Nasireddin Tousi in 7th century AH. The most significant feature associated with Maraghe observatory is the fact that architecture is employed to achieve astronomical purposes in this site. The reason for preferring observatory by astronomers was the fact that these units are superior to wooden...

A Virtual Observatory (VO) provides enhanced distributed access to online astronomical data­sets, and frequently incorporates data processing and visualisation facilities. Almost all critical aspects of data­grid research and technology are encountered when developing a Virtual Observatory. Issues include interoperability of data­sets and processing software, metadata format standardisation, an...

The advent of the Virtual Observatory has begun an evolution in the space physics data environment. A number of nascent and discipline specific Virtual Observatories have started to emerge with an emphasis on data search and retrieval. As this new data environment takes shape an emphasis will be placed on interdisciplinary communication in attempts to address large scale and global problems. To...

As a scientific discipline, Astronomy is rather unique. We only have one laboratory, the Universe, and we cannot, of course, change the initial conditions and study the resulting effects. On top of this, acquiring Astronomical data has historically been a very labor-intensive effort. As a result, data has traditionally been preserved for posterity. With recent technological advances, however, t...

We are inventing techniques to increase variable source yields from image subtraction analyses. An example innovation that will improve detection efficiency by about 10% is presented. The MEGA image-subtraction pipeline is a software instrument that could evolve into a tool to do microlensing science with virtual observatories.
