Though the name sounds boring, the “Very Large Array”, abbreviated as VLA, is known to be one of the largest telescopes in the world. It is built and setup in a desert outside Magdalena, New Mexico, and covers hundreds of miles in diameter space. The whole device consists of 27 separate radio antennas. Each antenna
Photography has become more interesting and fascinating with the introduction of panoramic images. This technology not only brings in wide angle images, but also helps the viewer to get images that are more close to the human field. The images make us feel like we are seeing the image through our eyes, then and there.
