Of the 25 to 30 research assistants accepted at the National Radio Astronomy Observatory each year, some are stationed at the Charlottesville, Virginia, headquarters, some at the 27-antenna Very Large Array in Socorro, New Mexico, and some at the 361-foot Robert C. Byrd Green Bank Telescope (GBT) in Green Bank, West Virginia. For those at the GBT, the internship comes with an unusual requirement: no cellphones.
DLP (Digital Light Processing), a low-cost leader in big-screen HDTV technology, uses a chip with thousands of micromirrors to display pictures. But there´s a limit to how small the mirrors can become and still produce a good image. Texas Instruments, which makes the DLP chips, maxed out with its 1,280-by-720 array, short of the highest-quality HD resolution of 1,920 by 1,080 pixels.
